SEATTLE - Seattle Mariners pitcher Ian Snell, 0-5 with a 6.41 ERA, has been designated for assignment.
The Mariners on Tuesday recalled right-hander Brian Sweeney, signed as a minor league free agent on April 16, from Triple-A Tacoma.
The 28-year-old Snell was replaced in the rotation by Luke French on Monday in the 9-3 loss to the Cardinals.
Snell, who has a 38-53 career record with a 4.80 ERA, was acquired by the Mariners last July along with shortstop Jack Wilson as part of a seven-player deal.
The 36-year-old Sweeney was 2-1 with a 2.51 ERA in 28 2-3 innings of relief with 32 strikeouts and eight walks. Sweeney spent the last three seasons playing in Japan for the Nippon Ham-Fighters.
