Wyndham Championship winner Aaron Rai once shared an emotional story behind his iron covers, insisting they would stay with him despite all the criticism.On Sunday, August 11, Rai fired a 6-under 64 to win the Wyndham Championship. He accelerated to 18-under, beating Max Greyserman by two strokes.A few years ago, Aaron Rai appeared on SiriusXM PGA Tour Radio, where he shed light on the story behind his iron covers. Notably, he has faced online trolling for using them."It started from the age of four years old, when my dad used to pay for my equipment," he told Jason Sobel and Michael Collins of SiriusXM PGA Tour. "He paid for my membership, paid for my entry fees. It wasn't money that we really had, to be honest, but he'd always buy me the best clubs."He added that his dad used to clean each of his grooves with a pin and baby oil. He also used to put iron covers on his clubs to protect them."And I've pretty much had iron covers on all my sets ever since, just to kind of appreciate the value of what I have. It’s more out of principle and it’s more out of just the value of not losing perspective of what I have and where I am. The covers are going to stay," he added.When will Aaron Rai compete next?Aaron Rai will next compete at the FedEx St. Jude Championship, the first of the three FedEx Cup Playoffs. The event will take place from Thursday, August 15, to Sunday, August 18, at TPC Southwind in Memphis.Rai finished 25th in the FedEx Cup standings and made a 28-spot jump after winning the Wyndham Championship.
