LHP Tyler Alexander
Once thought to be a lock for the bullpen, Tyler Alexander has suddenly become in danger of being DFA'd. He has not looked good this spring. He has a modest 4.05 ERA as of this writing, but he's given up six hits and three runs while only striking out three in 6.2 IP. His velocity has also been down, hanging around 88-89 when he's usually 91-92.
The Tigers have several lefty options that have pitched better than Alexander, and could probably be better in his role. Tyler Holton, Chasen Shreve, and even Joey Wentz could be better in the role with better stuff than Alexander. I'm kind of shocked he's still here to begin with.
Even if he does make the team, I have a sneaking feeling he won't be here for long. If he's throwing 88 mph with no life like he has been this spring, then he's probably not long for this roster.
