The 36-year-old spent the past four seasons with the Kansas City Royals, although he was not on the postseason roster when the team made its World Series run in 2015.
Although his 91-108 record does not impress, he has been a workhorse over his career, surpassing 200 innings five times. He won a career-high 15 games in 2013 but was just 8-8 with a 70 ERA+ and a 1.91 strikeout-to-walk ratio last year, per Baseball-Reference.com.
Guthrie thanked Kansas City for his time with the team in an Instagram post:
The 12-year veteran won't provide much more than depth at the back end of the rotation, but Baseball-Reference projects that he'll win one more game than last season while posting a 4.83 ERA.
Texas can use all of the help it can get on the mound, as the team finished 23rd in MLB with a 4.24 ERA and 24th in the big leagues with a .262 batting average against last season.
