Reyes day-to-day with strained knee

Twins lefty sustained injury fielding a comebacker on Thursday

MINNEAPOLIS -- Twins left-hander Dennys Reyes has a strained ligament on the inside of his right knee, an MRI revealed on Friday.

Reyes tweaked the knee while fielding a comebacker to the mound in the seventh inning of Thursday's game at San Diego.

The left-hander entered the inning with two outs and faced only one batter. Padres right fielder Brian Giles hit a chopper back to the mound on a swinging bunt. Reyes had to field the ball and make the throw to first baseman Justin Morneau for the out. But during the play, Reyes did something to cause some slight inflammation in the knee.

Reyes said that doctors told him it would be one or two days before he could get back on the mound. He said that he wasn't immediately sore following the play, but felt the knee stiffen up after the team's long plane ride back from San Diego.

"It's getting better now," Reyes said after Friday's game.

Without Reyes, Craig Breslow will be the lone lefty in the Twins bullpen.

Breslow hasn't had very much experience as a situational lefty. After the Twins pinch-hit for Reyes in the bottom of the seventh in Thursday's game, Breslow came into for the start of the eighth to face one lefty, Adrian Gonzalez. But Breslow has spent the majority of his career as a long reliever. He said that he welcomes the chance to be placed in more late inning roles.

"I was always the guy that was brought up to fill in for a tired bullpen or maybe to hold things up while someone was hurt," said Breslow, who has pitched short stints with the Padres, Red Sox and Indians over the past four seasons. "So I was always the long guy or mop up pitcher. I haven't really been used situationally, but it's something I think I can do. I just think I have the versatility to face right-handers, also."
