New York Yankees slugger Jazz Chisholm Jr. had to exit the game after the fourth inning on Thursday, getting struck out on three pitches by Houston Astros ace Cristian Javier. Yankees manager Aaron Boone replaced the second baseman with Jose Caballero.Moments later, it was revealed that Jazz Chisholm Jr. had suffered a contusion in both knees on two separate plays. He suffered a left knee contusion during a play in the third inning when Jose Altuve’s helmet collided with his knee. Boone revealed that a second contusion on the right knee occurred after a grounder hit by Ramón Urías hit Chisholm hard.After the Yankees' 8-4 win, Boone spoke about the injury to the second baseman."It was just what happened in both places," Boone said. "So we had the hard ground ball where he kind of slammed down on one of the knees. And then on the throw down to second, with the collision there, it was the other. So I don’t think it’s anything major. At least that’s the sense right now. But we’ll see how he’s doing tomorrow."Despite losing Jazz Chisholm Jr. early, Yankees won 8-4Jazz Chisholm Jr. has been one of the Yankees top hitters this season.
