Detroit agreed to a one-year, $4 million contract with left-hander Francisco Liriano, giving the Tigers added pitching depth.

Liriano, 34, was 6-7 with a 5.66 ERA last season. He made 18 starts for Toronto and 20 relief appearances with World Series champion Houston, which acquired him at the July 31 trade deadline. He is 102-99 in a 12-year big league career.

Tigers general manager Al Avila said it has not been decided whether Liriano will start or pitch in relief.
