Team: Pittsburgh Pirates
Position: Starting Pitcher
While Andrew McCutchen leads the offense as he tries to win the Triple Crown, McDonald is leading the rotation with a 9-3 record and a 2.93 ERA for the Pirates. McDonald, who has never had a full season with an ERA under 4, has also already matched his career high for wins in a single season. If the McCutchen-McDonald combo can lead the consistently terrible Pirates to the playoffs, then there is only one question to ask: Is this the year that pigs finally fly?
