Opinion by Judge FARRIS; Dissent by Judge SILVERMAN.

We are asked to decide whether trial counsel’s closing argument on behalf of petitioner Lionel Gentry constituted ineffective assistance of counsel. Trial counsel’s election to ignore evidence in the record that helped his client and to highlight record and non-record evidence that hurt his client cannot be- defended as nonprejudicial “trial strategy.” We therefore reverse his conviction with instructions to grant the writ of habeas corpus unless the State chooses to retry Gentry.

I

There is no question that on April 30, 1994, Lionel Gentry stabbed his girlfriend Tanaysha Handy. The issue was whether he did so intentionally or accidentally.

A. The Prosecution’s Case

For a year and a half preceding the stabbing, Gentry and Handy lived together as boyfriend and girlfriend. At trial, Handy testified that on the fateful day she smoked crack cocaine and later went with Gentry to her aunt’s apartment. Once there, she and her aunt smoked cocaine. She then departed for another apartment in the building, a “crack house,” where she smoked more cocaine and drank liquor. Later that night, Gentry came to get her, they argued, and at some point she was stabbed. Handy could not remember the details of what happened.

Faced with her inability to recall the events of April 30th, the prosecution showed Handy her preliminary hearing testimony. Although Handy recalled testifying at the preliminary hearing, she couldn’t remember most of the answers reflected in the transcript, including the events surrounding the stabbing. At the preliminary hearing, Handy testified that Gentry had placed his hand around her throat and later stabbed her twice, the second stab wound landing a few inches away from the first wound. At trial, Handy testified that Gentry never grabbed her, but recalled being stabbed twice.

The surgeon who operated on Handy testified that she had suffered a one-inch stab wound laceration to the left lateral chest area. The surgeon specifically noted that Handy received a single stab wound.

The prosecution’s other witness was Albert Williams, a security guard working at a neighboring building. He testified that, at about 9:45 p.m., his attention was drawn to the nearby building when he heard a man and woman arguing. Williams and his partner Pedro looked out the window of their third-floor office from where they could see Gentry and Handy as well as another man about 15 feet ahead of the couple. Although he testified at the preliminary hearing that it was “pretty dark,” Williams testified at trial that it was “getting dark” and “it wasn’t that dark.” Upon redirect examination, he said that the area where the stabbing took place was “lighted up.”

Williams testified that he saw Gentry swing his hand into Handy with an object, hitting her left side, and that she leaned forward and screamed. He saw Gentry “grab[ ] her from falling to the floor.” He then witnessed Handy try to push him away while grabbing for the unidentified object in Gentry’s hand. At about this time, the second, unidentified man left Williams’ field of vision.

After the stabbing, Williams and his partner Pedro left the third-floor landing of their building, went down two flights of stairs to the first floor, and jumped a six-foot-high gate to assist Handy. He found the couple struggling over the knife. *1010 Williams heard Gentry and Handy saying things to one another but could not remember what they said. Williams and his partner Pedro intervened and subdued Gentry. Gentry never tried to run away and never punched at Williams or Pedro. Instead, Gentry kept trying to get back to Handy, saying, “she’s my girlfriend.”

B. The Defense Case

The defense case consisted entirely of Gentry’s testimony. According to Gentry, at about 10 p.m., he went looking for Handy within her aunt’s building. He found her getting high in a first-floor apartment “crack house.” To get to that apartment, Gentry had to pass through a gate, but because he did not have a key, he used a knife from the aunt’s apartment to open the lock. When he entered the apartment, Handy was in a back room with another man. Gentry and Handy began arguing and left the apartment, to be followed by a dope dealer. As they were walking down the alleyway between buildings, Gentry and the other man, the dope dealer, got into a physical altercation. Handy tried to intervene several times by grabbing Gentry; he repeatedly pushed her away. At some point, Gentry threatened the dope dealer with the knife and when Handy tried to intervene again, he pushed her away with his right hand, which carried the knife, and accidentally stabbed her. The dope dealer then ran off.

At first, Gentry neither realized nor believed that he had stabbed Handy, but once he figured out what had happened, he tried to help her. Williams and his partner then arrived on the scene and told him to back away from Handy. Gentry refused, repeatedly saying “that’s my woman,” until finally he was handcuffed by Williams and Pedro. Gentry testified that he never intended to stab Handy.

After Gentry testified about the stabbing, defense counsel asked about Gentry’s prior convictions. Gentry testified that he had been convicted only once, though he had clearly been convicted previously of burglary, grand theft, battery on a police officer, and being a felon in possession of a firearm. On direct examination, he expressed confusion over whether the term “conviction” covered “plea bargains.” On cross-examination, he was impeached by the prosecution’s serial recitation of his prior convictions, all of which he acknowledged in open court while still expressing confusion over whether “conviction” covered cases for which he plead'ed guilty and did not receive jail time.

C. Closing Arguments

In her closing argument, the prosecutor zealously advocated for a guilty verdict. She expressed sympathy for Handy and her unfortunate circumstances — the fact that Handy was a pregnant drug-addict with three children — and argued that Handy’s preliminary hearing testimony should be believed despite her protestations at trial that she could not remember what had happened. The prosecutor then argued that Gentry’s testimony was “a pack of lies,” and that the testimony of eyewitness Williams, who had no reason to he, contradicted Gentry’s version of the events.

In contrast, defense counsel’s summation to the jury was casual and perfunctory. The argument in its entirety was as follows:

In her rebuttal argument, the prosecutor capitalized on the weakness of defense counsel’s summation. She pointed out that, despite defense counsel’s suggestion to the contrary, the jury could and should decide who was lying and who was telling the truth, as is consistent with the concept of a trial by jury. She then repeated that *1012 Williams’ testimony was believable, dispos-itive, and clearly contradicted Gentry’s testimony.

The jury deliberated for about six hours before finding Gentry guilty of assault with a deadly weapon in violation of California Penal Code §§ 254(A)(1) and 12022.7(a). Due to his prior convictions, Gentry was sentenced to 39 years to life. On direct appeal, Gentry argued that his attorney had rendered ineffective assistance by, in closing argument, failing to present a defense and making disparaging remarks about Gentry. The California Court of Appeals affirmed his conviction and sentence, and the California Supreme Court denied his petition for review.

Gentry then petitioned for a writ of ha-beas corpus in the district court. The magistrate judge issued a report and recommendation recommending dismissal of the petition with prejudice. The district court adopted the R & R and dismissed the petition. Gentry then appealed.

We granted a Certificate of Appealability limited to the issue of whether defense counsel’s summation violated Gentry’s Sixth Amendment right to effective assistance of counsel.

II

We review de novo the district court’s denial of Gentry’s 28 U.S.C. § 2254 habeas petition. See Shackleford v. Hubbard, 234 F.3d 1072, 1077 (9th Cir.2000). A federal court may grant a writ of habeas to a state prisoner only if the state court’s rulings “resulted in a decision that was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States,” or were “based on an unreasonable determination of the facts in light of the evidence presented in the state courts.” 28 U.S.C. § 2254 (d). “[I]t is not enough that the defendant convinces the federal court that, in its independent judgment, the state-court decision” applied the law incorrectly. Bell v. Cone, — U.S. -, 122 S.Ct. 1843, 1852 , 152 L.Ed.2d 914 (2002). Rather, to warrant habeas relief, the defendant must show that the state court applied federal law to the facts of his case in an “objectively unreasonable manner.” Id.

The California Court of Appeals deemed trial counsel’s closing argument to be an exercise of sound trial strategy that did not prejudice the outcome. We find that conclusion to be not only incorrect, but also to be an objectively unreasonable application of federal law.

Ill

To prevail on a claim of ineffective assistance of counsel, Gentry must show both that counsel’s performance was deficient, and that the deficient performance prejudiced the defense. 1 See Strickland v. Washington, 466 U.S. 668, 687 , 104 S.Ct. 2052 , 80 L.Ed.2d 674 (1984); Visciotti v. Woodford, 288 F.3d 1097, 1105 (9th Cir.2002). When considering whether counsel’s performance was deficient, we are highly deferential to counsel’s performance, indulging a presumption that “under the circumstances, the challenged action might be considered sound trial strategy.” Bell, 122 S.Ct. at 1852 (internal quotations omitted). To show prejudice, Gentry must show that *1013 “there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different.” Id. (quoting Strickland, 466 U.S. at 694 , 104 S.Ct. 2052 ).

A. Deficient Performance

Gentry “must show that counsel’s representation fell below an objective standard of reasonableness.” Strickland, 466 U.S. at 688 , 104 S.Ct. 2052 . The California Court of Appeals determined that the performance of Gentry’s counsel was not deficient, reasoning that he “addressed pertinent issues of the case, including the reliability of Williams’ testimony, whether [Gentry] intended to stab Handy, and the significance of the prior impeachment evidence.” That conclusion is objectively unreasonable.

What is most striking about trial counsel’s closing argument is that he mentioned a host of details that hurt his client’s position, none of which mattered as a matter of law, while at the same time failing to mention those things that did matter, all of which would have helped his client’s position. Instead of asking the jury to acquit his client, he made only a passive request for it to reach some verdict. Although he told the jury that the case hinged on Gentry’s credibility, trial counsel’s assertions that he did not know “what happened” or “who is lying” implied that even he did not believe Gentry’s testimony. He referred to Gentry as a “bad person, lousy drug addict, stinking thief, jail bird.” He didn’t discuss Handy’s unreliable testimony, the relevance of Williams’ inability to see the stabbing clearly on the issue of intent, the consistencies between Williams’ and Gentry’s testimony, the government’s failure to produce Williams’ partner “Pedro” who was purportedly a disinterested witness, and the fact that a one-inch deep wound inflicted by a six-inch knife would be consistent with an accidental stabbing if Handy was flimsily clad. Beyond the meek, personal statement “I don’t know what happened,” trial counsel did not even argue that the government had failed to meet its burden of proving beyond a reasonable doubt that Gentry intended to stab Handy.

The prosecution’s case hinged on (1) the jury believing Handy’s preliminary hearing testimony and disbelieving her trial testimony, and (2) the jury accepting that Williams’ testimony contradicted Gentry’s testimony and indicated Gentry’s intent to stab Handy. Defense counsel never discussed Handy’s testimony, instead choosing to react to the prosecutor’s expression of sympathy to the victim by noting, “I don’t care that Tanaysha is pregnant. I don’t care that she has three children.... What does that have to do with this case?” His sole reference to Williams’ testimony was “Pretty dark. Dark. It was light. Those are the three versions of his testimony with regard to what he saw and what he saw.”

Trifling comments about inconsequential aspects of the case cannot be excused as trial strategy. At trial, Handy testified that at the time of her stabbing, she had been using crack cocaine “24 hours a day” for more than five years. She had also smoked “a lot” of crack in the early morning hours on the day of the preliminary hearing and was feeling its effects when she testified. She acknowledged that when she is high, she sees “weird things,” including ghosts. She testified at trial and at the preliminary hearing that she was stabbed twice when there is no question she was stabbed only once. In closing argument, defense counsel mentioned none of this.

Williams’ testimony is not inconsistent with an accidental stabbing. From the third floor of a neighboring building, Williams witnessed Gentry strike Handy with an object later found to be a knife. *1014 Williams testified that after he ran downstairs and hopped over a fence, all three of them struggled over the knife, but when the knife fell to the ground, Gentry didn’t try to retrieve it, he kept moving toward Handy while saying again and again, “she’s my girlfriend.” Williams’ testimony about the lighting is important, but only to the extent to which it casts doubt on the conclusion that Gentry stabbed Handy intentionally. Trial counsel’s only comment on any part of Williams’ testimony was “[t]hose are the three versions of his testimony with regard to what he saw and what he saw.” Such statements qualify, at best, as passive recitations of facts, not as argumentation.

Gentry’s version of the events is not, of course, the only one worthy of credence. Far from it. The record shows that at trial he was at times agitated, confused, and evasive. He demonstrated the stabbing by inappropriately touching the prosecutor. He may have deliberately lied about his past convictions, though it is impossible to discern why he would do so, especially when the first questions about them were posed by his counsel. Little of Gentry’s testimony may, in fact, be true, even in light of the evidence suggesting the possible defense of accident. But none of this alters trial counsel’s duty to meet an objective standard of reasonableness in representing his client during closing argument. See, e.g., United States v. Swanson, 943 F.2d 1070 (9th Cir.1991) (finding defense counsel’s representation to be deficient where he conceded in closing argument that no reasonable doubt existed and proceeded to discuss the importance of the judicial system).

Closing argument is not simply a pro forma aspect of the criminal case, but an essential one:

Herring v. New York, 422 U.S. 853, 862 , 95 S.Ct. 2550 , 45 L.Ed.2d 593 (1975). The perfunctory and ineffectual closing argument by Gentry’s trial counsel constituted deficient representation. The California Court of Appeals’ decision to the contrary was unreasonable.

B. Prejudicial Effect

To demonstrate prejudice, Gentry bears the burden of showing a reasonable probability that, but for trial counsel’s unprofessional errors, the result of the proceeding would have been different. Strickland, 466 U.S. at 688 , 104 S.Ct. 2052 . “A ‘reasonable probability’ is less than a preponderance: [t]he result of a proceeding can be rendered unreliable, and hence the proceeding itself unfair, even if the errors of counsel cannot be shown by a preponderance of the evidence to have determined the outcome.” Visciotti, 288 F.3d at 1108 (quoting Strickland, 466 U.S. at 694 , 104 S.Ct. 2052 ).

The California Court of Appeals found there to be “overwhelming evidence of [Gentry’s] guilt.” We disagree. The sole question is one of intent. The most damn *1015 ing evidence of intent was Handy’s preliminary hearing testimony that Gentry grabbed her throat before stabbing her twice, testimony given under the influence of crack cocaine, later disavowed, and shown to be inconsistent with the physical evidence of a single stab wound. The other circumstantial evidence was Williams’ testimony that Gentry and Handy struggled over a knife, an object that was later dropped and ignored in Gentry’s attempt to get closer to his girlfriend.

The jury was presented with an ineffectual closing argument by defense counsel that failed to address the only aspects of the case that mattered. Nevertheless, the jury deliberated for six hours before returning a verdict. We find there to be a reasonable probability that the result of the trial would have been different in the absence of trial counsel’s deficient performance during closing argument. The California Court of Appeals’ decision to the contrary was unreasonable.

IV

Trial counsel’s rambling, perfunctory closing argument violated petitioner Lionel Gentry’s Sixth Amendment right to effective assistance of counsel. The California Court of Appeals’ decision to the contrary was an objectively unreasonable application of federal law. We reverse the district court’s denial of a writ of habeas corpus, vacate Gentry’s conviction, and remand to the district court with instructions to grant the petition for a writ of habeas corpus unless the State within a reasonable period grants a new trial.

REVERSED AND REMANDED WITH INSTRUCTIONS.

. At oral argument, Gentry conceded that the Supreme Court’s recent decision in Bell v. Cone, — U.S. -, 122 S.Ct. 1843 , 152 L.Ed.2d 914 (2002), made it clear that Strickland’s requirement that a defendant show both a deficiency and prejudice applies to the circumstances presented here. We therefore do not address his abandoned argument that prejudice should be presumed in accordance with United States v. Cronic, 466 U.S. 648 , 104 S.Ct. 2039 , 80 L.Ed.2d 657 (1984).
