"We'll talk about [details] more after his surgery," said manager A.J. Hinch. "Obviously, Jed has been a big part of our team so far and we expect him to be a big part of the team in the second half."
Lowrie, who had a .432 on-base percentage and eight extra-base hits along with 10 RBIs while starting 18 of the Astros' first 19 games, is already on the disabled list for the injury, which he sustained sliding into home during Monday's game in San Diego. It's the second year in a row a hand injury has sidelined Lowrie, who is in his second stint with Houston.
