Cook had a decorated college career at the University of Arkansas. He was a two-time Southeastern Conference Scholar-Athlete of the Year, and in his sophomore year earned all-America honors when he finished 10th individually at the 2011 NCAA Championship. In 2010 he was named to the SEC All-Freshman team. He served as a mainstay in the Razorback lineup during his college career with 48 tournaments played, a 73.37 career stroke average and nine top-10 finishes. Cook was the runner-up at the NCAA Fayetteville Regional in 2013, earning him all-central region accolades.
Professional career
Cook turned pro in 2014. He finished T-130 in Web.com Tour Q-school, but never got to play a Web.com Tour event due to his finish in Q School and limited status. In the summer of 2014, he made it into the FedEx St. Jude Classic through Monday qualifying, finishing tied for 13th place, at 5-under-par. Cook has played on the Adams Pro Tour. His career earnings as of April 1, 2015 were over $100k. In April 2015, Cook made it into the Shell Houston Open through the Monday qualifier, finding himself in contention in short order. With a 4-under-par 68 on Thursday, Cook made a strong close on Friday, with four consecutive birdies to win a spot in the final group along with Andrew Putnam and Phil Mickelson. On Saturday of the tournament, Golfweek said Cook "did not fold under the pressure of playing alongside Phil Mickelson," and carded a 2-under 70 as he headed into Sunday's final round one off of Jordan Spieth's lead, tied for second place at 203 with first-round leader Scott Piercy and Johnson Wagner. On the final day, Cook finished at −10 and tied for 11th, one position short of automatic entry into the Zurich Classic of New Orleans, the next full-field PGA Tour event. His earnings for the tournament were $135,000. At the 2015 Barbasol Championship, Cook Monday qualified his way to a T6 finish. That gave him entry into the RBC Canadian Open, where he finished T7. Cook earned enough non-member FedEx Cup points to qualify for the 2015 Web.com Tour Finals. He ended the Finals 51st among players who had not earned their cards through the regular season, one place short of full Web.com Tour status and avoiding Q School. Cook earned his PGA Tour card during the 2017 Web.com Tour season and earned his first PGA Tour win at the RSM Classic in November 2017.
