As an amateur, Martin played in three major championships and was the runner-up at the 2009 U.S. Amateur. Having turned professional in 2010, he won in his second professional event,[2] and finished runner-up at qualifying school for the PGA Tour at the end of the year.
In 2011 on the PGA Tour, Martin made the cut in 12 of 25 events and failed to earn enough money to retain his card for 2012. He played on the Web.com Tour in 2012 and 2013, picking up his first tour win at the 2013 United Leasing Championship. He finished second on the 2013 Web.com Tour regular season money list to earn his 2014 PGA Tour card. On October 19, 2014, Martin played the last four holes in 4-under-par, including a 46-foot eagle putt on the 16th hole to earn his first career PGA Tour win at the Shriners Hospitals for Children Open by two strokes over Kevin Streelman.[3]
