The good: Wacha has seen his FB velocity increase the past two seasons
The question: So? He still really didn’t pitch that well despite throwing harder.
The good: Lowest xFIP since his best season.
The question: So? His HR/FB was atrocious and he pitched in the best (for pitchers) home run park in the AL East
The good: I agree he’s probably replacing Perez and not ERod.
The question: Why not just upgrade when replacing Perez, too? Also, maybe he’s not replacing ERod, but does that mean Sale is?
