KANSAS CITY -- Erstwhile Brewers right fielder Corey Hart has been getting treatment for some swelling in his surgically repaired right knee, perhaps a side effect of his recent move back to first base.
At least, that's the team's best guess. The precise cause of Hart's issue is unknown, assistant general manager Gord Ash said.
"I think it's because he's doing so much diving at first base," manager Ron Roenicke said. "He dives and then he gets down to block balls, and I think he's just pounding the knee. It's not hurting, though there's a bit of swelling there."
Hart had surgery in Spring Training for tears to the meniscus in his knee. He recovered in time to be the Brewers' Opening Day right fielder.
He has impressed his coaches with a smooth transition back to first base, his original position but one Hart had not manned regularly since 2002. He made the move after the Brewers lost both Mat Gamel (season-ending knee surgery) and Travis Ishikawa (left rib-cage strain) to the disabled list.
"I love what he's doing there," Roenicke said. "His target's great. He doesn't mind getting down on the ground. If he has to get down there and block it, he gets down; if he has to five for a ball, he dives. I like what he does."
