SEATTLE — After days of debate, the Seattle Mariners have traded left-handed pitcher Jarrod Washburn to the Detroit Tigers in exchange for left-hander Luke French and minor-league prospect Mauricio Robles.

The Mariners announced the deal Friday morning, just hours before the non-waiver trade deadline arrived.

Washburn has turned around his career this season. After three lackluster years in Seattle, the left-hander is 8-6 with a 2.64 ERA this season.

Washburn will be a free agent this offseason, and the Mariners decided to maximize his trade value.

French has split the season between Detroit and Triple-A Toledo. He is 1-2 with a 3.38 ERA in five starts for the Tigers.
