CHICAGO - Five weeks into the season, the Twins are preparing to promote their 10th player from Class AAA Rochester.
After Wednesday's 3-2 victory over the White Sox, the Twins optioned catcher Steve Holm to Rochester, saying they will make a corresponding roster move before Friday's game in Boston.
No, Joe Mauer won't be ready to come off the disabled list by then, and the team did not make a trade or sign free-agent catcher Bengie Molina.
The Twins plan to promote either Danny Lehmann or Rene Rivera from Rochester. Neither is on the 40-man roster, but the team currently has 39 players on the 40-man.
Basically, the Twins just want to try something different. Holm batted .118 (2-for-17) and didn't impress the team defensively. Meanwhile, Drew Butera, an outstanding defensive catcher, is batting .111.
Rivera, 27, is batting .200 for Rochester but has previous major league experience with the Mariners.
Lehmann, 25, is viewed as another top defensive catcher. He started the year at Class AA New Britain and batted .462 (6-for-13) before moving to Rochester when Holm was promoted to the majors. Lehmann is batting .280 (7-for-25) for Rochester.
Before Wednesday's game, two others joined the squad from Rochester -- infielder Trevor Plouffe and outfielder Ben Revere -- replacing Jim Thome (strained oblique) and Jason Repko (strained quad), as they went on the 15-day DL.
Manager Ron Gardenhire said he plans to give Plouffe regular playing time at shortstop.
"Sure, why not?" Gardenhire said. "We're calling him up for that."
Revere will see spot duty in the outfield. He was batting .209 when the Twins promoted outfielder Rene Tosoni to replace injured Delmon Young but then went 13-for-25, raising his average to .293.
"When we called up Tosoni, we were talking about who was ready to come up, and they told me that Ben Revere was more apt to be sent to Double-A than the big leagues," Gardenhire said. "The last few days since Tosoni's come up here, it may have been a nice little wake-up call for him, which is a good thing."
• The Twins plan to activate Kevin Slowey from the disabled list Saturday, Gardenhire said. Slowey, who has been out with right shoulder bursitis, will be in a long-relief role.
• According to the Elias Sports Bureau, Francisco Liriano's two strikeouts Tuesday were the fewest a pitcher has had in a no-hitter since the Dodgers' Jerry Reuss had two strikeouts in a no-no against the Giants in 1980.
• Twins pitchers are averaging 3.8 walks per nine innings, among the worst walk rates in the majors, and they issued five more walks Wednesday, including four by Nick Blackburn. They also hit three batters, giving the White Sox a total of eight free passes.
