Outfielder Cole Gillespie has elected free agency after clearing waivers, according to the transactions page at CBSSports.com. The Diamondbacks designated Gillespie for assignment to create roster space for Mike Jacobs six days ago.
Gillespie spent time at the MLB level in 2010-11, but played the entire 2012 season at Triple-A. The 28-year-old posted a .308/.390/.494 batting line with 13 homers in 510 plate appearances for Reno this year. The Diamondbacks acquired Gillespie and Roque Mercedes from the Brewers for Felipe Lopez in 2009.
