Oliver, who Detroit took in the second round of the 2009 MLB Draft out of Oklahoma State, has been stellar with the Double-A Erie Seawolves. In his 14 starts, he has a 6-4 record with an ERA of 3.61 and 70 strikeouts.
Oliver has been moved up partially in response to starting pitcher Rick Porcello's sophomore slump. As a result, Porcello was recently sent down to Triple-A Toledo.
Oliver will face off against veteran pitcher Kris Medlen, who has been outstanding this season as well. Medlen has a 4-1 record with a 3.33 ERA thus far, pitching as both a starter and reliever.
