5. RP Andrew Vasquez
Here's a case where we're wondering why he was here in the first place. Vasquez had nice numbers for the Phillies on the surface — 2.27 ERA sure isn't bad. But then you look the 4.29 FIP, the high WHIP, the low K/9, and you realize that there was a reason why the Phillies DFA'd him.
Vasquez could not throw strikes consistently, and his stint with the Tigers was proof of that. In 12 games, he had a 8.31 ERA, a WHIP over 2 (!!!), a hits per nine over 11 and a walks per nine over 9 (!!!). He walked as many batters as be struck out.
It's kind of a shock an analytical mind such as Scott Harris didn't see the writing on the wall with Vasquez. Maybe he thought Chris Fetter and company could make some tweaks, but when even he can't fix you, you're kind of a lost cause.
This is a pretty easy one. The Tigers won't have to try very hard to find a lefty reliever who can be more effective than Vasquez.
