It was Mercy's first post-season appearance in over 20 years.  His Mavericks compiled a 17-28 record in 2011, including a 10-20 mark in ECC play.

Greiner has a successful track record as a head coach, and now holds a 381-296 career mark in 15 seasons including stints at Manhattanville for two years and Concordia (N.Y.) for 11 years.

Greiner is known for his recruiting and player development skills that have led to numerous All-Conference selections and seven All-Americans, including 2003 Division II National Player of the Year Mike Aviles, now with the Cleveland Indians.  He has had four players drafted and gone on to play in the professional ranks.

Greiner was voted by his peers as the 2002 NYCAC Coach of the Year after guiding his team to a 44-12-1 mark, which was a New York State record. He has also served two terms on the NCAA Northeast Regional Advisory Committee.
