With Rick Porcello struggling for the Tigers, it might be time to consider adding Drew Smyly.
Porcello's strong spring gives credence to the notion that spring stats should not be trusted. While Porcello is not as bad as he's pitched thus far, his 6.25 FIP indicates he's still been pretty awful. Smyly, on the other hand, had a pretty strong rookie season in 2012. He struck out nearly a batter per inning and limited walks effectively.
It's tough to chase wins in Fantasy, but given how the Tigers are expected to perform, Smyly might pick up his fair share of wins in the rotation. If he gets a slot in the rotation, he might be worth a shot in mixed leagues.
