Reds selected the contract of Zach Maxwell from Triple-A Louisville.

Luis Mey was sent down Thursday to open up a spot for Maxwell, who will be making his major league debut three years after the Reds drafted him in the sixth round out of Georgia Tech. Maxwell had a 3.17 ERA and a 59/32 K/BB in 49 2/3 innings out of the pen for Louisville. He averages 99 mph with his fastball, but poor control has always been an issue, and it would take some sort of breakthrough there to turn him into a quality late-game reliever.
