Oakland Athletics prospect Grant Desme is retiring from baseball to enter the priesthood.

Desme was recently selected the 2009 Arizona Fall League MVP and was considered one of the top prospects in Oakland's system.

The 23-year-old outfielder batted .288 with 31 homers, 89 RBIs and 40 stolen bases in 131 games at Class-A Kane County and Stockton last season.

He then hit .315 with a league-leading 11 home runs and 27 RBIs in 27 games in the fall league.

Desme was a second-round pick selection in the 2007 draft after being named Big West Player of the Year at Cal Poly San Luis Obispo.
