In 2014, Oliver struck out 85 batters in 64 innings with Triple-A Indianapolis of the Pirates' organization in his first season strictly as a reliever. That translated to 12 strikeouts per nine innings. However, he has struggled with his control, which is reflected in his walk rate of 6.6 batters per nine innings.
The Phillies selected Oliver in December's Rule 5 Draft. He made 10 appearances for the Phillies in the spring, going 2-0 with a 3.55 ERA. At the end of spring, the Phillies outrighted Oliver and he elected to become a free agent.
The Tigers drafted Oliver out of Oklahoma State in the second round of the 2009 First-Year Player Draft.
