McMyne spent the entire 2015 season in Double-A and saw some success at the level. He was named as a Mid-Season All-Star and the Southern League Relief Pitcher of the Month in May. For the season, he made 52 appearances and posted a 2.92 ERA with a 1.48 WHIP. Originally a fourth round pick in 2011 out of Villanova by the Reds, McMyne returned to Pensacola for the 2016 season. In the lower levels, McMyne was more of a strikeout pitcher, but that has not translated to Double-A just yet. He also has occasional spells with command issues.
