Since the introduction of designated events by the PGA Tour this year, all the top players are required to participate in every elevated event and can skip just one of the 17 designated events.The scheduling of the PGA Tour is such that players are on the golf course every week or two with little to no break in between.After finishing T4 at The Masters last week, Jordan Spieth is at Harbour Town Golf Links this week looking to defend the RBC Heritage, the last event he won. He hasn't skipped any designated events yet, which means he has consistently been on Tour.In addition to competing against the best golfers, Spieth will have to face another challenge when he tees off on Thursday, April 13. He recently reflected on the issue of playing too much golf, which was causing 'mental fatigue' and that he would need to look after his schedule moving forward."I think I played way too much golf into this," said Spieth during the final round interview of the 2023 Masters. "I came in mentally fatigued and then you overworked this week every year and um, I played way too much golf in the last, I mean this is eight out of ten weeks, so I need to change my schedule up going forward to be a little sharper this week. I think that has a lot to do with it."It's not just Spieth who has been affected by the busy PGA Tour schedule. A number of golfers have been affected by the injuries.
