The Arizona Diamondbacks have hired former Red Sox pitcher Daniel Bard to serve as a player mentor, one of four newly-created positions in the organization.

Arizona also hired Jonny Gomes -- who won the 2013 World Series with the Red Sox -- as hitting coach for the Rookie AZL D-backs.

Bard retired earlier this offseason after several comeback attempts.

The 32 year-old posted a 1.93 ERA for the Red Sox in 73 outings during 2010, then recorded a 3.33 ERA in 70 relief outings during 2011.
