SEATTLE (AP) -Cha Seung Baek, who struggled in his last few starts for the Seattle Mariners, was placed on the 15-day disabled list Friday with inflammation in his right shoulder.
Left-handed reliever Ryan Rowland-Smith was recalled from Triple-A Tacoma to take Baek's roster spot.
Baek was 3-3 with a 5.37 ERA in 11 starts with the Mariners, but he allowed 19 earned runs and 33 hits in his last four starts. Last Saturday in Houston, Baek lasted just four innings, allowing six runs and nine hits.
Ryan Feierabend, who started Friday night against Cincinnati, will take Baek's spot in the rotation.
``It's something we recently found out has been ongoing,'' Seattle manager Mike Hargrove said of Baek's injury.
This is Rowland-Smith's second stint with the Mariners. He was called up for four days last month, but did not appear in a game. Rowland-Smith was 3-4 with a 3.86 ERA in 24 appearances at Tacoma.
