A manga by Shinobu Kaitani (also the author of ''Manga/LiarGame'') which was adopted into a 25-episode anime series by Studio Creator/{{Madhouse}} in 2008,
''One Outs'' presents itself quite differently from others in its genre. While most sports series are focused on the importance of training, determination and teamwork (more often than not featuring high-school-age players), ''One Outs'' is mainly concerned with loads of money and incredible mind games in a pro baseball setting. The anime was produced by the team responsible for ''Manga/{{Akagi}}'' and ''Manga/{{Kaiji}}''; the protagonist is voiced by the seiyuu of the eponymous characters from those two series.

From Mangaupdates.com :

Kojima Hiromichi is the ace batter of the Lycaons - a notoriously weak baseball team that is often ranked at the bottom of the league. Determined to lead the team to victory prior to his retirement, Kojima takes a trip to a training camp in Okinawa, hoping to discover what factors the Lycaons lack.

Here, he happens upon a game dubbed "One Outs" - a gambling derivative of baseball - and is soundly defeated by a blond pitcher named Tokuchi Toua, who is claimed to have never allowed a hit in any of the 499 games he has played.

Kojima realizes that he has found the 'missing factor' and makes a wager with Tokuchi. Little does anyone know that the outcome of this gamble will dictate the fates of the Lycaons and all those connected to the team.
* AbsurdlyHighStakesGame: Sets the series in motion when Kojima wagers his career against Tokuchi's right hand.
* AccidentalAthlete: Kojima discovers Toua Tokuchi largely by chance.
* ArtisticLicenseBiology: There's no other explanation for how people are able to clearly overhear each other from hundreds of feet away. The announcers can always hear every single word Tokuchi says on the pitch, for example.
* BadAss: Toua, again.
* BadAssBoast: Toua, yet again. When he says he's going to strike someone out in three pitches, he means it.
* BarbieDollAnatomy: Tokuchi is shirtless in the opening animation, but he has no nipples.
* BatmanGambit: Tokuchi makes quite a habit out of pulling these.
* {{Bishounen}}: Takami Itsuki of the Chiba Mariners stands out among a cast of average-to-ugly characters.
* BoringInvincibleHero: Toua, for the most part, always recovers his losses and makes out like a bandit at the end of each game or string of games.
* BrutalHonesty: Toua does not hesitate to tell anyone exactly what he thinks of them.
* ButtMonkey: Arai. If anyone's going to look utterly stupid, it's usually him.
* CantGetAwayWithNuthin: Averted. Tokuchi spots players on a rival team cheating by stealing the Lycaons' signals. Does he call them on it? Not a chance. He mounts a man-in-the-middle attack and makes them lose face utterly.
* CheatersNeverProsper: Played straight in the second and third matches against the [[spoiler: Kobe Blue Mars]] -- though Toua's own methods for ensuring their victory were far from honest and by-the-book...
** Inverted in the third match against the Mariners where, in order to win, both teams have to intentionally and obviously cheat as much as possible.
* CharacterDevelopment: By the end of the series Toua is actually going out for drinks with the other members and taking part in pre-match meetings (for his own reasons, but still.)
* TheChessmaster: Toua
* CombatCommentator: Obviously, since this is a sports series.
* TheDogBitesBack: Happens to Saikawa a few times.
* DownToTheLastPlay: Quite a few matches are only won in the final inning.
* DreadlockRasta: Dennis Johnson's hairstyle.
* {{Expy}}: Toua, of {{Akagi}}. Their personalities are virtually the same.
* EvilGloating: Saikawa delights in this.
* FlawExploitation: Toua almost entirely relies on this to score his victories.
* FrameUp: One of the many, many methods Saikawa uses to try to reduce his debt to Tokuchi.
* GagLips: Manager Mihara, whose nickname among his team is "Fat Lips."
* GratuitousEnglish: "Big Mama", and Brooklyn's entire character.
** And the series' title and subtitle, with their questionable grammar.
* GambitRoulette: Quite a few times -- but the most notable example was during the third match against the Chiba Mariners.
* GoldenSnitch: The Lycaons' owner, Saikawa, occasionally makes certain games worth ''20 times'' more than others in terms of Toua's wages as well as the amount deducted from his annual salary, should he give up any runs. [[spoiler: Tokuchi wins every time - with only one exception - moving his annual wage from several million to several ''billion'' yen.]]
* [[spoiler: HeroicSacrifice: Toua, in his last game against the Mariners, pitches all 9 innings, giving up 36 runs and many more hits, on purpose, just to mess up with all the Mariners batters' form, and thus giving the other Lycaons pitchers a chance in the following games]].
* HoistByHisOwnPetard: What happens to the [[spoiler: cheating Blue Mars team and its manager (and mastermind behind the entire process) once Toua turns their rule-breaking into their greatest weakness.]]
** Saikawa frequently suffers from this during his attempts to out-gamble Tokuchi.
* HyperAwareness: Tokuchi's greatest strength is his super-awareness of everything going on around him.
* IdealHero: Kojima
* TheLancer: Ideguchi
* LikeAGodToMe: Manager Mihara says this to Tokuchi in one episode when he's trying to butter him up.
* MundaneMadeAwesome: Really, actual baseball (even in the pro leagues) isn't even one thousandth as interesting as this anime manages to make it seem.
* {{Narrator}}
* NominalHero: A particularly good example of this, as he could just as easily have been the villain had ''One Outs'' been a more true-to-type sports manga.
* NotCheatingUnlessYouGetCaught - The mentality of the Blue Mars team. Subverted in an episode where Tokuchi and the Mariners cheat blatantly and obviously because they ''want'' to get caught.
* ObfuscatingStupidity: Toua pulls this off a couple of times, despite having a face that looks anything but stupid. Mostly used in the matches against the Bugaboos, during which he [[spoiler: pretends to be weak at fielding to lull the other team's manager into a false sense of security.]]
* OhCrap: Used by the Blue Mars when they realize the trick ball makes it impossible to pick Toua off at base.
* OrderedToCheat: The Blue Mars' standard MO, though unusually for the trope they have no objections to doing so.
* ThePlan: It's quite difficult to tell sometimes what kind of plan Toua is using but they often work.
* PornStache: Okabe of the Eagles has a classic one.
* PoseOfSupplication: Tokuchi forces a Blue Mars player into one on national TV after a FrameUp backfires.
* PutMeInCoach: Inverted. Tokuchi is too good at what he does, and the executive who manages the team deliberately sends him in only when he believes that Tokuchi will make a mistake.
* TheReveal: Lengthy ones after every trick.
* RuleOfSeven: Toua's jersey number is 77.
** LuckySeven
* {{Seinen}}
* ShirtlessScene: The opening animation shows Tokuchi shirtless.
* SirSwearsalot: Brooklyn and most foreign players.
* SlowClap: Tokuchi does this to Ideguchi in a later episode.
* SmokingIsCool: Toua smokes like a chimney -- especially in the manga.
* TalkingIsAFreeAction: Not as blatantly overused as in other sports series -- but there's still no way the umpires would allow players and managers to talk to each other so frequently and long-windedly during a game (without even calling for time-outs). Still, it's understandable - since most of the mind-play is so complicated that few viewers would be able to figure out what was going on unless it was explained in detail.
* ThisCannotBe: Frequently uttered by Tokuchi's opponents.
* TrashTalk: Usually started by the enemy, but Tokuchi gives as good as he gets.
* UnderdogsNeverLose: The Lycaons are a pretty mediocre team, but they start winning matches like wildfire after Toua joins.
** Averted when Toua points out that the reason they've always been underdogs is not due to a glaringly obvious lack of skill -- but strategically weak game plans, bad coaching, thoughtless management, low self-esteem and a great deal of misconceptions regarding what a baseball game is all about.
* WebcomicTime: In the author's comment to volume 16 (released 2006) Kaitani notes that even though the series is entering its 8th year, in-universe it's still 1999.
* WhatHappenedToTheMouse: Kojima's spectacled lackey disappears completely after episode 4, save for a brief cameo in episode 25.
* WhyDontYaJustShootHim: More like "Why don't ya just hire him properly?" Saikawa's henchman points out he could save a lot of money by just signing Tokuchi to a normal player's contract, but he refuses.
* WorthyOpponent: Tokuchi states he has been looking for one.
* [[spoiler: WoundedGazelleWarcry: Toua sacrificed himself, but in doing so, gave the Lycaons a serious chance at beating the Mariners, as they all worked together as the perfect team, over the more talented Mariners.]]
* XanatosSpeedChess: Again, plenty of times; especially during the second and third matches against the Blue Mars.
* YouAreNotAlone: The difference between baseball and One Outs.
