The Athletics have received outfielder Eliezer Mesa from the Rockies to complete the Mark Ellis trade, reports MLB.com's Jane Lee (on Twitter). Colorado acquired Ellis from Oakland for a player to be named later at the end of June.
Mesa, 23 in November, did not rank as one of the Rockies' top 30 prospects in the 2011 edition of Baseball America's Prospect Handbook. He hit .256/.320/.311 with eleven steals in 53 games for Colorado's High Class-A affiliate this summer, missing time with injuries. Mesa is a .287/.336/.389 career hitter in more than 1,100 minor league plate appearances. He's the nephew of former big leaguer Jose Mesa.
