Kevin Mulvey, one of the pitchers the twins got in Johan Santana trade, is headed to Arizona as part of the Jon Rauch trade.
Judging from the above statement from the Twins, there's cash flowing in both directions as well, but that's probably a technicality. The trade was Rauch for Mulvey, and I'm fine with that. Happier with that than I was with Carl Pavano for Yohan Pino, because Rauch will be around next season.
Mulvey hadn't developed the way I, and I assume the Twins, expected he would when they got him. Here are his pro ball numbers. Note the slight regression while repeating Triple A this year. Almost exactly the same innings, but more walks, fewer strikeouts and a worse ERA. He certainly didn't improve.
Which is why it's Jeff Manship (above) getting the start today against the White Sox. It's not that the Twins expect Manship to be great; by all accounts, they think he's up too soon. But the Twins clearly had come to regard him as a better option than Mulvey.
The trade of Mulvey, coupled with the fact that Phil Humber has been dropped from the 40-man roster twice this season, breaks the direct take from the Santana trade down to Carlos Gomez and Deolis Guerra, although the Twins now have Rauch as a spinoff. Guerra has at least had a decent bounce-back season after a rough 2008 — note the vastly improved walk and strikeout rates.
