HOUSTON -- Astros shortstop Marwin Gonzalez could be done for the season after an MRI performed Friday discovered a torn ligament in his left ankle. He was injured stepping awkwardly on first base in Thursday's loss to the Giants.
Gonzalez was in a protective boot as he left Minute Maid Park on Friday, but interim manager Tony DeFrancesco said surgery wasn't going to be necessary. Gonzalez won't be placed on the disabled list considering rosters can be expanded to 40 players on Saturday.
"Injuries are a part of baseball, and we've seen it all summer," DeFrancesco said. "You try to get a full roster, and now we have Sept. 1 coming, and I'm sure there will be some [roster moves on Saturday]. We should get some help on the way."
The Astros will also have to fill the spot on the roster vacated by outfielder Ben Francisco, who was traded to the Rays on Friday for a player to be named later. Astros general manager Jeff Luhnow said the club will call up three to five players, though not all at once.
Gonzalez, a Rule 5 pick, was hitting .234 with two homers and 12 RBIs, and had started 27 of 43 games at shortstop since Jed Lowrie was placed on the disabled list on July 15.
