Mulvey was selected by the New York Mets in the second round (62nd overall) of the 2006 amateur draft. He made his professional debut in the Rookie League with the GCL Mets August 19, 2006. A day later, he was promoted to the Binghamton Mets, New York's Eastern League Double-A affiliate.
Mulvey was one of the players included in the Johan Santana trade between the Mets and Twins on January 29, 2008. 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.
New York Mets (second stint)
The Mets signed Mulvey to a minor league contract on March 10, 2012.[10] They assigned him to the Class AA Binghamton Mets.[11]
On May 26, Mulvey retired. Mulvey was 0–1 with a 5.59 ERA in 13 games with Binghamton.[12]
