The Minnesota Twins have placed right-hander Scott Baker on the 15-day disabled list and optioned right-hander Jason Marquis to Double-A New Britain, with neither starter ready in time for the regular season.
The moves were made Wednesday, the Major League Baseball deadline for setting 25-man opening day rosters.
Baker has been bothered by tendinitis in his throwing elbow. He was put on the DL retroactive to March 27, making him eligible to rejoin the rotation on April 12. Marquis missed two weeks of spring training to tend to his seriously injured 7-year-old daughter, and the Twins want him to catch up with some time in the minors.
Rookie right-hander Liam Hendriks will take one spot this weekend, starting Sunday at Baltimore. The Twins have an off day Tuesday.
