Philadelphia Phillies president Dave Dombrowski on Friday said "it's clear" that first baseman Rhys Hoskins has a torn left ACL and is expected to be out for the season, but that the slugger will seek a second opinion.
"He will need to have surgery," Dombrowski told reporters. "I would be shocked if he doesn't. And that will put him out ... for the season. That's what we're planning."
Hoskins, who with 30 home runs and had 79 RBIs last season, suffered the injury while fielding a grounder in a spring training game Thursday.
He was backing up to play a chopper on Thursday when the ball popped out of his glove. Soon after, he fell to the ground and clutched his left knee. Teammates gathered around him before he was taken off of the field.
Dombrowski on Friday said that Darick Hall would be called upon to fill the void at first base as a result of Hoskins' injury.
"I do feel comfortable to say that we like Darick Hall a lot," Dombrowski said. "We feel that he'll get the majority of the playing time at first base. ... We think he's ready to step up and be a big league player."
The 27-year-old Hall hit .250 with 9 home runs and 16 RBIs in 41 games for the Phillies last season.
Hoskins' injury was another blow for the Phillies, who will be without top pitching prospect Andrew Painter for another few weeks because of a sprained ligament in his right elbow. Slugger Bryce Harper also isn't expected back until around the All-Star break after undergoing Tommy John surgery in November.
