He broke a commitment to the University of Portland by signing with the Pirates for a $600,000 signing bonus. He made his professional debut for the Gulf Coast Pirates of the Rookie-level Gulf Coast League in 2012 and also started one game for the State College Spikes of the Class A-Short Season New York–Penn League.
