José Caballero’s Delay-of-Game Warning Highlights Pitch-Clock Enforcement Issues

In the sixth inning of the Yankees’ 8–3 win over the Toronto Blue Jays, shortstop José Caballero raised his head for more than eight seconds on two pitches from reliever Spencer Miles. Plate umpire Steven Jaschinski issued a delay-of-game warning, saying a strike would be called for a repeat. Caballero, manager Aaron Boone, Jaschinski and crew chief John Tumpane discussed the call, extending the game by over two minutes.

The eight-second rule, adopted in 2023, requires a batter to be ready to engage by the eighth second after the pitcher receives the ball; pitchers may not begin their motion until the batter is set. MLB has stressed uniform enforcement, though officials note frequent adjustments to the rule’s interpretation.

Aaron Boone said the Yankees have “a good handle” on Caballero’s rhythm and believe his method is “within the rules.” He added the team gave instructions to align with the umpiring crew. Caballero countered that he is not delaying the game and called the umpire’s claim inaccurate. He also noted that “they’ve been changing the rule every single day,” and said he will seek pre-game clarification from umpires.

Opponents have labeled Caballero’s deliberate tempo “irritating,” recalling a 2023 incident in which his style bothered Seattle Mariners pitcher Gerrit Cole.

Caballero maintains he does not exceed the eight-second limit, while the umpire’s warning suggests a violation. MLB has not issued a definitive clarification, leaving the rule’s precise application unresolved.

ESPN

• “So I feel like we have a good handle on it and certainly understand what he's trying to do and he has a rhythm and a process to help him get locked and we think it's within the rules,” — Aaron Boone, New York Yankees manager

ESPN

• “That's what he said and then whenever he talked to everyone on his speaker, he said that I was delaying the game which if I delayed the game that's a strike because I'm going over the time that I have,” — José Caballero, shortstop

ESPN

• “I might have to ask the umpire right before the game starts to see what is the new ruling today,” — José Caballero

ESPN

• “There's some gamesmanship in what he does but he's a smart gritty player,” — Aaron Boone

The episode underscores ongoing challenges in applying the pitch-clock rule consistently. Caballero plans to request pre-game clarification from umpires, and the Yankees will open a three-game series against the Chicago White Sox while monitoring MLB guidance.
