Houston Astros star Jose Altuve will serve as designated hitter for Game 3 of the American League Championship Series after aggravating a right knee injury in each of the first two games of the series against the Boston Red Sox.Altuve, a second baseman, went on the disabled list in July due to soreness in the same knee and missed nearly four weeks.”It’s bugging him,” Astros manager A.J. Hinch told reporters prior to Game 3. “He’s doing everything he can to play and he’s trying not to make a big deal out of it. I know moving him to the DH spot brings the first couple questions about it. But he’ll do anything we ask, which is commendable.”The six-time All-Star is batting second in the Game 3 lineup against Boston right-hander Nathan Eovaldi.Marwin Gonzalez will move from left field to second base. Tony Kemp draws the start in left.”Putting Marwin at second is not a disadvantage,” Hinch said. “This was going to be the lineup regardless of the positioning.”Boston is moving Eduardo Nunez back into the lineup at third base against Houston left-hander Dallas Keuchel. Left-handed-hitting Rafael Devers will begin the game on the bench.The series is tied at one game apiece.
