Starlin Castro out 7-10 days
"It's similar to what happened to him last year at this time," Renteria said. "Just being cautious with him. It shouldn't set him back at all for the regular season."
Castro injured his right hamstring sliding into second base on a steal attempt in the first inning in Sunday's 5-3 loss to the Kansas City Royals. Last year, Castro injured his left hamstring running the bases in a game and missed two weeks of spring training.
"It's not too bad, like last year," Castro said Sunday. "It [hurts] just a little bit. It's early right now. I'll take a couple days and be back again."
Renteria said starting second baseman Darwin Barney will see time at shortstop, as will Emilio Bonifacio. Top prospect Javier Baez will also get more playing time in Castro's absence. He's slated to start on Monday against the Milwaukee Brewers.
