Remember the 2015 John Deere Classic playoff? King Spieth edged out Tom Gillis in a heartbreaker, denying Gillis his first PGA Tour win at age 47. Some on Tour even joke that Spieth 'ruined' Gillis’ career, since that win would’ve meant a two-year exemption and a life-changing moment. Now, with Spieth sidelined by injury, fans are revisiting that rivalry. Was it just tough luck for Gillis, or did Spieth’s clutch gene truly change the course of two careers? #Sports #Golf #PGATour
