Austin Jackson began his Minor League rehab assignment on Monday night with a start at designated hitter for Triple-A Toledo at Rochester. The Tigers' center fielder and leadoff man, who has been out since May 14 with a pulled left hamstring, went 0-for-5 with three strikeouts in his first game in four weeks. Beforehand, Detroit manager Jim Leyland said that while the hope is that Jackson could be ready to rejoin the Tigers for Friday's series opener at Minnesota, they could be flexible with the plan. Jackson is expected to play about seven innings in center field for the Mud Hens on Tuesday. The Hens are off on Wednesday, so Jackson will rest before starting at DH or in center on Thursday at Syracuse. What happens from there depends on how Jackson says his leg feels after running in game conditions.
