He was drafted three times - first, in the 15th round of the 2005 amateur draft by the Atlanta Braves. Next, by the Braves in the 45th round of the 2006 amateur draft, and last by the Anaheim Angels in the 16th round of the 2007 amateur draft. He was signed by scout Casey Harvie for a $125,000 bonus.
Tobin began his professional career in 2007, pitching for the Orem Owlz and AZL Angels, going a combined 4-1 with a 2.08 ERA in 14 games (13 starts). In 2008, he pitched for the Cedar Rapids Kernels, going 2-3 with a 3.13 ERA in eight starts. He pitched in only three games in 2009 (undergoing Tommy John surgery in the spring of that year), all for the Rancho Cucamonga Quakes and all relief appearances. That year, he posted a 0.00 ERA in 2 2/3 innings.
In the 2010 Rule V Draft, Tobin was taken by the Chicago Cubs. Though he had not played in 2010, the Rangers traded for him for cash considerations in December of that year. He made the team out of spring training in 2011 and made his debut in the second game of the season, coming in relief of starter Colby Lewis with a large lead against the Boston Red Sox. In one inning, he gave up 2 runs on 2 walks and a hit, that hit being Jacoby Ellsbury's first home run since 2009. He made only four appearances altogether before going on the disabled list for the remainder of the season with an injury to his pitching elbow.
