"He's been outstanding," Astros manager Bo Porter said of Maxwell. "Defense, big hits. We'll need other guys to step up."
"It's tough," said Bud Norris, who got the win in Tuesday's 3-2 victory. "He's a staple in center field. We'll miss his bat in the lineup and his leadership."
Maxwell was hit with the bases loaded and two outs, making the score 3-1. Maxwell, who is batting .234 with six RBIs, was removed between the fourth and fifth innings and replaced by Brandon Barnes, who will most likely get most of the time in center field.
"I've had things happen before," Maxwell said. "What doesn't kill you, makes you stronger."
Grossman, a switch-hitter, was hitting .324 with 13 runs scored and a .452 on-base percentage in 19 games for Oklahoma City, going 9-for-22 in his past five games. Acquired from the Pirates in the Wandy Rodriguez trade at the Trade Deadline last year, he hit .267 with a .371 on-base percentage in 36 games at Double-A Corpus Christi.
