NEW YORK — New York Yankees shortstop José Caballero was at the center of a tense scene on Monday night — one in which benches cleared, words were exchanged, but no punches were thrown.Teammates held Caballero and Pittsburgh Pirates reliever Dennis Santana back as the pair shouted at each other from across the diamond at Yankee Stadium, a back-and-forth that stretched on for more than a minute and ended with both sides retreating to their dugouts.The flare-up came in the eighth inning of an eventual 8-5 Yankees win. The spark that ignited it? A familiar one.Santana said he took exception to Caballero’s pre-pitch routine, which includes stalling until the pitch clock strikes eight seconds. MLB rules state that is the latest a hitter can wait before he acknowledges the pitcher.If the pitcher doesn’t do it in time, he is penalized a ball. If the batter fails to do so, he’s hit with an automatic strike.“He can do it,” Santana said, “but not every pitch. That’s when I get mad, like, ‘Oh my god. What’s going on? That’s too much.'”Santana was irked that Caballero stuck with his routine, even though the Yankees were up three runs and had a runner on first. He said he yelled at Caballero to speed things along, though he was aware Caballero does that for virtually all the time, regardless of the circumstances.“It’s nothing against him,” the pitcher said. “It’s just a game. I got caught up in the game.”
