White was injured in 2013 but spent the 2012 season with the AZL Indians after Cleveland selected him in the 24th round of the 2012 draft out of South Georgia College. He posted a 2-0 record with a 2.70 ERA in 13.1 innings, striking out 15 batters while walking only five. Due to new league eligibility rules, White counts as a "Rookie-1" as he did not accumulate 20 innings or 10 appearances during his lone pro season.
