Clayton Richard (illness) gave up two runs in six innings Tuesday in his second minor league rehab start with Triple-A Tucson.
Richard, out since May 4 with an intestinal virus, gave up five hits and no walks while striking out four. The southpaw threw 65 out of 94 pitches for strikes. It should be enough for the Padres to activate him from the disabled list.
Twins transferred OF Darin Mastroianni from the 15-day disabled list to the 60-day disabled list.
The move clears a spot for Chris Colabello on the 40-man roster. Mastroianni is scheduled to undergo surgery Wednesday to repair a bone chip on his left ankle and will be sidelined until the second half of the season.
Twins purchased the contract of 1B/3B Chris Colabello from Triple-A Rochester.
Colabello, who had a strong performance for Italy during the World Baseball Classic, was hitting .358/.417/.659 with 12 home runs, 39 RBI and a 1.076 OPS through 46 games this season in Triple-A. The 29-year-old played seven seasons in the Canadian-American Association, so he makes for a tremendous story.
Twins placed 3B Trevor Plouffe on the 7-day disabled list with a concussion.
Plouffe took a knee to the head Tuesday night when he tried to break up a double play with a slide at second base. He'll need to be cleared by MLB doctors before returning to action. The Twins have called up Chris Colabello to take his spot on the active roster.
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.
