Trade history between the Baltimore Orioles and Arizona Diamondbacks.
The Orioles and Diamondbacks haven’t been frequent trading partners over the years with just four player-for-player deals made. The most recent move being a deal for outfielder Michael Bourn. The Orioles sent minor league outfielder Jason Heinrich to Arizona. Heinrich never made it out of the low minors and found himself in independent ball soon after the trade.
There was, however, one notable deal made between the two franchises back on December 6th of 2010.
- To Baltimore: IF Mark Reynolds and a player to be named later (catcher John Hester)
- To Arizona: RHP David Hernandez and RHP Kam Mickolio
Hernandez went on to have two very good seasons and two below-average seasons out of the bullpen for Arizona after the deal and has continued to find success as a journeyman reliever for three additional teams, including a repeat stint with the Diamondbacks in 2017. With Arizona, Hernandez went 15-18 with a 3.64 ERA and 1.14 WHIP, striking out a career-high 10.3/9 IP during his tenure. Mickolio would go on to give up five runs on ten hits across his only six innings of work at the major league level with Arizona.
Reynolds played a key role in that magical 2012 season for the Baltimore Orioles. He hit just .221 in each of his two seasons with the Orioles but slugged 60 home runs and 53 doubles with a .328 OBP and .458 slugging percentage across his 290 games in an Orioles uniform.
The former University of Virginia standout has since played for six different franchises and is currently sitting at 298 career home runs. Both Hernandez and Reynolds are free agents as of December 2019.
