Oakland A's outfield prospect Grant Desme is reportedly turning in his baseball cap for a priest's collar.

Fox Sports' Jon Paul Morosi has confirmation from an A's official that the 23-year-old Desme is retiring and is "serious" about a career change.

This kind of decision must have been made with a great deal of thought. So go ahead and take Desme off your draft lists in keeper and dynasty leagues.

Desme was the only minor leaguer with at least 30 home runs and 30 stolen bases last season when he hit a combined .288 with 31 homers and 40 steals for Class A Kane County and High-A Stockton.

He was also the Most Valuable Player in the 2009 Arizona Fall League (I even specifically mentioned him in a Windup post while I was there in Phoenix) when he hit .315 and led the league with 11 homers. Baseball America had him ranked as the A's 8th-best prospect entering the 2010 season.

Meanwhile, the line of the day came on Twitter from Kevin Goldstein of Baseball Prospectus: "Well, somebody's church softball team is gonna get WAY WAY better soon."
