Professional career Milwaukee Brewers The Milwaukee Brewers selected Nelson in the second round of the 2010 Major League Baseball draft.

Nelson started the 2013 season with the Double-A Huntsville Stars. He was promoted to the Triple-A Nashville Sounds on June 5. He was promoted to the majors on September 3, made his debut on September 6, and made his first major league start on September 28.

Prior to the 2014 season, Nelson was rated the Brewers' top prospect and 96th best prospect in baseball by Baseball America. Nelson began 2014 back at Triple-A Nashville, and dominated the Pacific Coast League to the tune of a 10–2 record, 1.46 ERA, and 114 strikeouts. Nelson was even named 2014 PCL Pitcher of the Year. He made one spot start for Milwaukee against the Miami Marlins due to a minor injury suffered by Yovani Gallardo on May 25, and recorded his first major league win, pitching scoreless innings with 3 walks and 6 strikeouts.

On July 10, Nelson was recalled again to join the starting rotation in place of the home run-prone Marco Estrada. He got his first career base hit during his July 17 start. Nelson sustained an injury on September 17 against the St. Louis Cardinals when Tommy Pham hit a line drive that ricocheted off his head.
