Not so long ago Jeff Niemann was a big part of the Rays’ plans, but the former No. 4 overall pick missed most of 2012 and all of 2013 with a fractured fibula followed by shoulder surgery and now Tampa Bay has dropped him from the 40-man roster.
Niemann chose free agency, so he’ll be looking for a new home at age 30 after throwing 544 innings with a 4.08 ERA for the Rays.
Niemann should draw plenty of interest as an inexpensive bounceback candidate capable of being a mid-rotation starter.
