The A's placed pitchers Dallas Braden and Joey Devine on the 15-day disabled list Tuesday, retroactive to March 24.
Pitching coach Curt Young made the decision that Braden would not join the team in Japan on March 15, saying it would be too difficult for Braden to get in his regular work.
REWIND: Braden to miss Japan trip
Braden, 28, continues to rehab his shoulder after undergoing season-ending surgery to repair a torn capsule last May. He made just three starts prior to the injury, going 1-1.
"What I need to do," Braden told the San Francisco Chronicle, "is get myself ready to pitch without any potential conflicts in my workout schedule."
Braden who authored MLB's 19th perfect game on Mother's Day of 2010, will try to regain his 2010 durability; he started 30 games for the A's, going 11-14 with a 3.50 ERA.
Devine, 28, hits the DL with right biceps tendinitis. In 2011, he appeared in 26 games, going 1-1 with a 3.52 ERA.
Devine and Braden will be eligible to come off the disabled list prior to the A's three-game home series against the Royals beginning April 9.
The A's are in a unique situation with spring training games to play after their opening series. They are required to reduce their roster to 25 players by April 4, but are not allowed to carry more than 25 players for the Japan series. As a result, pitchers Tyson Ross and Tommy Milone and first baseman Daric Barton will be inactive for the Japan series, getting the A's roster to 25 active players.
XON HILL, Md. — A person familiar with the negotiations says free agent outfielder Matt Holliday and the New York Yankees have agreed to a $13 million, one-year contract.
The person spoke on condition of anonymity Sunday night because the agreement had not yet been announced.
Holliday, who turns 37 next month, fits into the Yankees strategy of signing veterans to short-term deals while pivoting toward a youth movement.
A seven-time All-Star, Holliday was drafted by Colorado in 1998, traded to Oakland after the 2008 season and then dealt to St. Louis the following July. He hit .246 with 20 homers and 62 RBIs in 110 games this year, missing substantial time after his left thumb was broken when he was hit by a pitch on Aug. 11.
Holliday became a free agent when St. Louis declined his $17 million option.
The Seattle Mariners have signed free agent lefty reliever Marc Rzepczynski to a two-year contract.
Rzepczynski's deal is fo $11 million over two years. Jerry Crasnick of ESPN first reported details of the contract.
The Mariners also signed right-handed reliever Casey Fien on Saturday. Left-hander Dean Kiekhefer and righty Zach Lee were designated for assignment.
The 31-year-old Rzepczynski was a combined 1-0 with a 2.64 ERA in 70 games for Oakland and Washington this season. He then pitched three times in the NL playoffs for the Nationals.
Rzepczynski has made at least 70 appearances in each of the last three years. He's also pitched for Toronto, St. Louis, Cleveland and San Diego in an eight-season career.
The 33-year-old Fien was 1-1 with a 5.49 ERA in 39 games for Minnesota and the Los Angeles Dodgers.
The 27-year-old Kiekhefer made his major league debut last season and pitched 26 times in relief for the Cardinals. Seattle claimed him off waivers from St. Louis last month.
