MINNEAPOLIS -- Twins left fielder Delmon Young was a late scratch from the lineup against the Rays on Wednesday, and was subsequently placed on the 15-day disabled list, retroactive to April 19, with with a strained left oblique.
Outfielder Rene Tosoni was called up from Triple-A Rochester to take his place on the roster.
Young, who has been out since April 18 with sore ribs, was originally scheduled to make his return Tuesday, but a rainout pushed it back to Wednesday. Young was penciled in as the left fielder and was slotted fifth in the batting order before telling manager Ron Gardenhire he couldn't get loose during batting practice about two hours before the game.
"He tried to swing today but never could get loose," Gardenhire said. "He said it was too cold and he never could feel right or loose. There was soreness, so I told him I had to put him on the DL and he said it was the right thing."
Minnesota was forced to shuffle its lineup in Young's absence, as Matt Tolbert came off the bench to start at second base and batted ninth, while Luke Hughes shifted from second base to first base, Michael Cuddyer switched from first base to right field and Jason Kubel went from right field to left field. Justin Morneau remained as the club's designated hitter.
Tosoni, meanwhile, was called up to the Majors for the first time in his career. The 24-year-old was batting .286 with a .329 on-base percentage and .500 slugging percentage with three home runs, six doubles and 16 RBIs in 19 games with Rochester.
"He's been playing very well down there," Gardenhire said.
No timetable on Mauer's return
MINNEAPOLIS -- Catcher Joe Mauer is eligible to return from the disabled list on Thursday, but Twins manager Ron Gardenhire said he won't be activated and doesn't know when the former American League MVP will return to the team.
"It's not until he gets his legs and body underneath him," Gardenhire said. "I have no timetable. None whatsoever."
Mauer, who has almost completely recovered from the flu, was placed on the DL with bilateral leg weakness on April 13. He's also expected to play in a few rehab games in the Minors before his return, but Gardenhire said he didn't know when Mauer will be ready to take the field.
Thome, Repko sit out with minor ailments
MINNEAPOLIS -- The Twins held designated hitter Jim Thome and outfielder Jason Repko out of the lineup on Wednesday, as both are battling minor injuries, according to manager Ron Gardenhire.
Thome suffered an oblique strain on his last swing during Sunday's game, and Repko is nursing a strained quadriceps. "Thome has a slight oblique strain and he's day to day right now," Gardenhire said. "Repko has a little quad thing, that's supposedly no issue. But he's still out today."
The moves left Minnesota with little flexibility on the bench, as backup catcher Steve Holm was the only fully healthy player on the bench Wednesday night.
Swarzak starts Game 2; Pavano to go Sunday
MINNEAPOLIS -- The Twins shuffled their rotation for this week, as right-hander Anthony Swarzak was recalled from Triple-A Rochester after Wednesday's 8-2 loss to the Rays, and is slated to start Game 2 of Thursday's doubleheader at Target Field.
Right-hander Eric Hacker, who was tentatively scheduled for spot start duty before pitching 3 1/3 innings in relief of Francisco Liriano on Wednesday, was optioned to Rochester to make room for Swarzak on the roster.
Swarzak, who made 15 starts with the Twins in 2009 and posted 4.87 ERA in four starts with Rochester this season, will start on three days' rest.
"It was better suited for Swarzak than our other options," Twins manager Ron Gardenhire said. "We had to have somebody for the second game or for Saturday, so instead of doing something silly we just wanted the second game to be one our callups."
Gardenhire also announced right-hander Carl Pavano is sick with the flu and will have his scheduled Saturday start pushed back to Sunday.
Right-hander Nick Blackburn will still start Game 1 on Thursday, and will be followed in the regular rotation by right-hander Scott Baker on Friday in Kansas City and left-hander Brian Duensing on Saturday.
Slowey throws in extended spring game
MINNEAPOLIS -- Twins right-hander Kevin Slowey, on the disabled list with right shoulder bursitis, threw 47 pitches in a rehab appearance in extended Spring Training action on Wednesday.
Slowey made his first rehab appearance with Fort Myers on Saturday, allowing one run on one hit in an inning.
Manager Ron Gardenhire said Slowey could rejoin the club as early as this weekend, and will continue to serve as a reliever upon his return.
"We'll probably see him in Kansas City or Chicago," Gardenhire said. "He'll be out there pitching one way or another."
With chill in air, club breaks out ear-flap hats
MINNEAPOLIS -- With temperatures expected to dip into the mid-30s, Twins players did their best to stay warm on Wednesday night against the Rays.
The club was shipped specially designed hats with built-in ear flaps to stay warm, with a few of the players opting to at least try them out during batting practice.
"I think it's pretty good to keep the ears warm," said Australia native Luke Hughes. "It's like a beanie underneath there."
Michael Cuddyer said he'd wear the new warm cap, but also admitted that it's tough to keep from feeling cold while out on the field. The Twins, though, did install a portable heater in the dugout and there are heaters in the bullpen to help relievers stay warm.
"We're not going to keep warm, simple as that," Cuddyer said with a laugh. "I'm going to wear a couple of layers, some tights, and I'm still going to be cold."
