Tiger Woods has been struggling with his putting so far this season, particularly inside of 6 feet.
Some of that, no doubt, has come from putting on poa annua grass in his three PGA Tour starts this season at Torrey Pines, Riviera and Club de Golf Chapultepec, where he three-putted six times on greens that confound a lot of elite players. However, Woods has seen some things he doesn't like in his putting stroke, and he's turned to Justin Thomas' putting coach, Matt Killen, to be a set of eyes.
Killen was seen working with Woods on Monday at The Players Championship, and the 80-time PGA Tour winner continued to work with Killen on Tuesday at TPC Sawgrass.
Woods, who first got to know Killen during the 2016 Ryder Cup in Minnesota, explained Tuesday this isn't the first time he and Killen have worked together. They've spent time together near Woods' home in Jupiter, Fla. Killen has worked with Thomas back into his amateur days, and Woods, who practices frequently with the 2017 PGA champion, has an affinity for turning toward guys who work with his regular practice buddies. After all, Killen has seen Woods' putting stroke enough times now to have a good understanding of his mechanics.
Killen, a 32-year-old from Kentucky, also works with J.B. Holmes, whose putting was phenomenal down the stretch at Riviera, en route to a fifth PGA Tour title.
At this point in the season, Woods would rank 80th in strokes gained putting if he'd logged enough rounds to qualify for the stat.
Woods hasn't employed any kind of golf coach since ending his work with biomechanics expert Chris Como in 2017.
