Rafael Betancourt (groin) is scheduled to undergo an MRI on Wednesday.
Betancourt left Tuesday's game with a tight right groin, an issue which has lingering since late April. He's hoping to avoid the disabled list, but the Rockies may decide that a couple of weeks of rest is the best course of action. Rex Brothers is the likely favorite for saves if Betancourt needs to miss time, but Wilton Lopez could also figure in.
Trevor Plouffe was tested for concussion symptoms after he took a knee to the head Tuesday on a slide into second base.
"He got hit pretty hard," said Twins manager Ron Gardenhire. "They're doing the testing on him right now. He took a knee right to the head. We'll know more later." The Twins should provide an update on his status Wednesday.
Matt Guerrier struck out a pair over two scoreless innings of relief Tuesday against the Rockies.
He entered the contest with just four punch outs, so last night's performance qualifies as an outburst. Guerrier used to be a holds machine for the Twins, but he's posted just 19 over the past three seasons for the Dodgers, four less than he had in his last year in Minnesota. An elbow injury cost the veteran most of last season. He owns a 3.45 ERA, 1.21 WHIP and ugly 6/6 K/BB rate over 18 appearances.
Matt Belisle tossed a scoreless inning of relief in Tuesday's victory over Arizona.
The veteran has notched a 3.86 ERA, 1.20 WHIP and 21/7 K/BB rate in 21 games. He's also sixth in the National League with eight holds.
Xavier Paul has hit whenever he's been called upon by the Reds, slashing .270/.400/.405 over 90 plate appearances.
Since he was called up by the Reds last July, Paul has hit as well as any reserve outfielder, batting .294/.389/.438 with four homers and 20 RBI in 160 at-bats. Paul has cost Cincy four runs below replacement defensively in limited opportunities this year, so he'll have to keep his lumber warm to steal at-bats.
Casey Fien struck out two in a perfect inning of relief Tuesday against the Braves.
The 28-year-old right-hander has a 4.19 ERA over 11 appearances. After getting pounded in limited run for the Tigers between 2009-2010, Fien has rejuvenated his career up north, posting a stingy 2.87 ERA and 1.01 WHIP over 56 games since the Twins called him up on the Fourth of July, 2012.
J.P. Howell's first season in Los Angeles is off to a strong start, as the left-hander has a 2.89 ERA through 19 appearances for the Dodgers.
Coming off a stellar 2012 campaign, having posted a 3.04 ERA, 1.21 WHIP and 42/22 K/BB ratio in 55 appearances for the Rays, Howell inked a one-year, $2.85 million contract with the Dodgers. Howell is allowing a few more base runners this season (1.34 WHIP compared to 1.21 in 2012), but his strikeout rate is slightly up and, more importantly, he hasn't surrendered a home run yet.
Andrew Miller is proving his 2012 breakout was no fluke, posting a 3.86 ERA and 24/8 K/BB rate over 20 appearances.
The sixth overall pick in 2006 has successfully saved his career in Boston's bullpen. Miller went 21-29 with a 5.79 ERA between 2006-2011, mostly as a starter for the Tigers, Marlins and Red Sox. He hasn't started a game in the last two seasons and has rewarded Boston with a 3.48 ERA over 73 appearances. Miller's current strikeout rate is by far the best of his career.
