DETROIT -- The Minnesota Twins don't want to catch whatever the Boston Red Sox are carrying.

The Twins, who arrive tomorrow for a three-game series at Comerica Park, have asked that the visiting clubhouse be fumigated, Red Sox general manager Dave Dombrowski told NESN.

Several Red Sox have been out of the lineup while fighting a flu bug. Even Red Sox announcer Dave O'Brien was forced to leave Saturday's broadcast mid-game with flu symptoms.

Tigers manager Brad Ausmus said he hadn't taken any precautions to keep the Red Sox bug from spreading down the concourse to the Tigers.

"No kissing the other players," he joked. "We don't want to transmit any infections."

More progress in Lakeland

Tigers right fielder J.D. Martinez continues to make strides in his rehab from a sprained foot.

Martinez hit off a tee on Saturday, took a break Sunday for a treatment-only day, and could hit soft-toss or in the batting cage as early as today.

Even more encouragingly, he threw from 150 feet on Saturday.

"Everything's been all positive with J.D.," Ausmus said. "I would say we're on the positive side of the schedule."

Upton out

Tigers left fielder Justin Upton was scratched from the lineup about 30 minutes before the scheduled start time with upper back tightness.

There was no further word on the severity of the injury. Upton was on the field during batting practice prior to the game.

Andrew Romine started in left field in his place.
