 Biographical Information
C.J. Riefenhauser reached the major leagues in 2014.
Riefenhauser was picked by the Tampa Bay Rays in the 20th round of the 2010 amateur draft. The scout was Milt Hill. He split the summer between the Princeton Rays (1-0, Sv, 2.84) and the Bowling Green Hot Rods (1-0, 1 R in 9 IP). In 2011, he dazzled for Bowling Green (6-5, 2.31, 1.01 WHIP) but was less successful with the Charlotte Stone Crabs (1-3, 4.14). Had he qualified, he would have been second in the Midwest League in ERA behind Greg Billo. He was picked as the MWL All-Star left-handed starter while Billo was chosen as the right-hander.
C.J. split 2012 between Charlotte (7-8, 4.76) and the Montgomery Biscuits (1-1, 3.44). He tied for 4th in the Rays chain in losses. Moving to the bullpen, he was untouchable in early 2013; after 34 games for Montgomery, he was 4-0 with 11 saves, a 0.51 ERA and .153 opponent average. He was promoted to the AAA Durham Bulls. He also was a late addition to the US team for the 2013 Futures Game, replacing the injured Taylor Guerrieri. He entered the game in the 8th inning, relieving Jimmy Nelson with a slim 3-2 lead. He retired Christian Bethancourt, Yeison Asencio and Dilson Herrera in order. In the 9th, Kyle Crick relieved and the US locked up a 4-2 win.
