The Tigers designated righty reliever Robbie Weinhardt for assignment to create room on the 40-man roster for lefty Adam Wilk, according to the team. Wilk takes the spot of Phil Coke on the 25-man roster, as Coke hit the DL with a right foot bone bruise.
Weinhardt, 25, had an 8.80 ERA in 15 1/3 Triple-A relief innings this year after posting a 1.57 mark in 34 1/3 frames at the level in 2010. Prior to the season, Baseball America ranked Weinhardt 12th among Tigers prospects, 15 spots ahead of Wilk. To put that in perspective, BA ranked the Tigers' farm system 25th overall. BA says Weinhardt uses a near-sidearm delivery to generate groundballs with his sinking fastball, and also employs a slider.
