The other three players the Mets sent to the Twins were pitchers Philip Humber, Deolis Guerra and outfielder Carlos Gómez.^[6] At the time of the trade, Baseball America ranked Guerra, Gomez, Mulvey and Humber the second, third, fourth and seventh best prospects in the Mets organization, respectively.^[7]

Arizona Diamondbacks

On September 1, 2009, Mulvey was claimed off waivers to the Arizona Diamondbacks. The Arizona Diamondbacks sent cash considerations to the Twins. This claim was made shortly after a trade that sent pitcher Jon Rauch to the Twins for a player to be named later, which later became cash considerations. According to MLB.com "essentially that (the player to be named later) is Mulvey."^[8] He was designated for assignment on August 16, 2011.^[9]

The Diamondbacks released Mulvey on February 29, 2012.
