ST. LOUIS -- Rookie shortstop Brad Miller was taken out of the Mariners' game against the Cardinals in the fifth inning Saturday because of a strained left hamstring, and he will likely be sidelined the next several games, according to manager Eric Wedge.
"It's mild, but I'm sure it's at least going to be a couple days," Wedge said after the Mariners beat the Cardinals, 4-1. "Tomorrow will give us a much better idea where we're at."
Miller, 23, took over a starting role for Seattle from Brendan Ryan when he was called up from Triple-A in late June and has hit .260 with six home runs and 31 RBIs in 69 games.
He was 1-for-2 in Saturday's game before apparently injuring the hamstring while running out a sacrifice bunt in the top of the fifth. Rookie Carlos Triunfel replaced him in the bottom of the fifth. It was Triunfel's first appearance since being recalled from Tacoma on Sept. 3.
Triunfel wound up contributing a sacrifice bunt and a sacrifice fly in two plate appearances, driving in the final insurance run in the ninth with a fly ball to right field.
Ryan had been backing up Miller at shortstop until he was traded to the Yankees on Tuesday.
