The Twins have placed struggling right-handed pitcher Mike Pelfrey on the disabled list.
According to the Pioneer Press, Pelfrey reported a groin injury Friday during a meeting with Twins manager Ron Gardenhire and pitching coach Rick Anderson.
Gardenhire said Pelfrey's arm is healthy, but the groin issue may have caused Pelfrey's velocity to diminish in Thursday's loss.
Pelfrey is just five starts into his new two-year $11 million contract. He has struggled in those five starts. Pelfrey is 0-3 with a 7.99 earned run average.
Once Pelfrey's groin heals, he will likely have a rehab assignment, which could last up to 30 days.
To replace Pelfrey in the rotation, fellow right-handed pitcher Sam Deduno will move from the bullpen to make his first start of the season on Tuesday in Cleveland.
In seven appearances Deduno has posted a 2.89 ERA in 18 2/3 innings.
Pelfrey's move to the DL leaves the Twins with an open roster spot, they will call up a position player in time for Saturday afternoon's game.
Additionally outfielder Chris Parmelee isn't on the 40-man roster and Kenny Wilson, who the Twins acquired earlier has not played above Double-A.
