When drafted, Heidenreich was viewed as a very raw high school prospect, but the California native has made steady improvements as a pro thanks to a reportedly strong work ethic. Currently, his fastball is a low 90s sinker, but given his frame adding velocity is a realistic possibility. His change is becoming closer to an average pitch. He also features a slider, which is his third best pitch. Heidenreich showed his improvement in 2010 with a strong showing for Bristol (76 IP, 2.49 ERA, 58 K, 11 BB) and held his own for Kannapolis in 2011. He is a good control pitcher, but will need to develop his change or slider further to be able to get more strike outs. Projecting him is extremely difficult right now because he won’t be a good prospect unless he continues to improve, but he has the makeup and projectable body to do so.
Heidenreich returned to the White Sox organization for 2015, after being traded to Houston mid-2012. His 2013 was pretty ugly results-wise, and in the AFL that fall he was essentially made-over by the Astros mechanically. He also had some minor injuries that year. 2014 saw him battle through that process, and the results weren’t much better as he gave up a lot of hits but also struck out nearly a batter an inning back down in A+. In 2015 he made 21 starts with Winston-Salem and had no trouble with Carolina League hitters (2.76 ERA, 1.6 BB/9, 7.1 K/9), and was promoted to Birmingham where he showed well in 4 starts (24 IP, 22 H, 9 ER, 6 BB, 23 K). He’s likely back at Birmingham to start 2016.
Major League Outlook: back end starter or long man
