As reported by Tim Healey of MLB.com, Santan underwent surgery in April 2013 to repair his torn shoulder capsule and continues to recover from the surgery. He signed a Minor League contract with the Orioles in March, but has yet to appear in a game at any level. The last time he pitched in a game was back in August 2012 while with the Mets.
When Santana is ready to join the Orioles, he'll join a rotation that consists of Chris Tillman, Ubaldo Jimenez, Wei-Yin Chen, Miguel Gonzalez and Bud Norris. The Orioles rotation has had only 20 quality starts this season, which ranks 27th in the league.
Santana, a 12-year Major League veteran, has pitched for the Twins and the Mets. He is a two-time Cy Young Award winner and four-time All Star. During his last season in 2012, he went 6-9 with a 4.85 ERA in 21 starts. Santana has a career record of 139-78 with a 3.20 ERA. In 2,025 2/3 innings, he's allowed only 1,726 hits and 567 walks, while striking out 1,988.
