Jason Jennings spent six years in Colorado and somehow emerged with a positive record and a positive ERA+. But not unscathed. A torn flexor tendon cropped up, and Jennings crapped out.
In Houston in 2007, Jennings went 2-9 with 6.45 ERA before surgery mercifully ended his season. At Texas in 2008, he was 0-5 with an 8.56 ERA before going under the knife a second time.
This time, Jennings and the Rangers believe, the repaired tendon will hold. Jennings says he feels better than he did at any point in 2008. And he'll get a chance to prove it when pitchers and catchers report to Rangers camp next week. On Friday, the Rangers signed Jennings to a minor-league contract.
Jennings may start the season in the minors, working his way back into shape. But the Rangers believe he can win back a place in the rotation. For a minor-league deal, it's worth finding out.
