Davis, 22, spent last year at Class A Tampa and Trenton, where in 24 starts and 1 relief appearance he combined to finish 8-7 with a 3.86 ERA while ranking second among all Yankees farmhands with 129 strikeouts in 130.2 innings (132h, 26bb). He was added to New York's 40-man roster in November.
The 6-foot-5, 245-pound righthander was selected by the Yankees in the 14th round of the June 2011 first-year player draft out of Dixon High School in Holly Ridge, NC.

Renda, 24, originally was selected by Washington in the second round of the 2012 draft out of the University of California. He began 2015 rated the Nationals' 12th-best prospect and hitter with the best strike zone discipline but on June 11 was traded to the Yankees in exchange for RHP David Carpenter.
In 127 appearances last season in Class AA at Harrisburg and Trenton, Renda combined to hit .269 with 30 doubles, 2 triples, 3 HR, 44 RBI and 23 stolen bases in 29 attempts. He also recorded 43 walks and just 39 strikeouts.

Selected out of Vanderbilt University in the fifth round of the June 2009 draft, the 6-foot-3, 215-pound righthander in his minor league career has recorded 312 strikeouts in 367.2 innings. He will be on the Reds' 40-man roster.
