Twenty-eight holes under tough conditions Sunday at demanding Riviera Country Club was just too much for Tiger Woods.”I got tired,” he admitted to reporters ( via PGATour.com ) after fading with four bogeys in his last 10 holes at the Genesis Open. Genesis Open: J.B. Holmes edges out Justin Thomas to win 5th PGA Tour event With the temperature in the 40s and wind gusts approaching 30 mph, Woods finished at 6 under, eight shots back of winner J.B. Holmes.”I don’t know if I’m the only one, but I definitely felt it today. Wind, cold. I was at 10 (under) and I slipped four shots coming in. That’s the way it goes,” he said. Related News His 2019 schedule has been a topic of some speculation. He said last year’s bounce-back PGA Tour season, that also included the Ryder Cup, left him too tired by year’s end. His fade in tough conditions this weekend reinforces the point that at 43 he has to pick his spots judiciously, likely with an eye toward the majors.After playing in Mexico, it wouldn’t be a surprise if he opted to sit out the next week at his hometown Honda Classic in Palm Beach Gardens, Florida.After that there are few opportunities for time off ahead of the Masters: After the Honda, there’s the Arnold Palmer Invitational at Bay Hill (one of Woods’ favorite events because of its legendary namesake), followed by The Players Championship, the Valspar Championship (at Innisbrook’s Copperhead course, a good shot-making test ahead of Augusta) and the WGC-Dell Match Play Championship with the 2019 Masters two weeks after that (April 11-14) as the first major of the year. Suffice it to say he wasn’t the only one. Justin Thomas, the tournament leader for most of the way, shot a 75. Adam Scott carded a 76 and Jordan Spieth finished with an 81 to cap a tournament that battled the elements from Thursday on.“The weather, the long days and just the temperature, trying to be focused for long, long periods of time, it took a toll on a lot of us out there today,” Woods said.Woods said he planned to take Monday off (“The sticks aren’t coming out of the travel bag,” he joked in a post-round standup) and won’t start trying to prepare until Tuesday for his trip this week to the WGC-Mexico Championship in the high altitude of Mexico City.That pre-Mexico prep will revolve around the flat stick.“Eventually I made a few bad swings, but to be honest with you, it was one of the worst weeks I’ve ever had on the greens,” Woods said of his play at Riviera.“I made a few in spurts, but I didn’t really have the pace right and I was struggling with the lines early in the week. Finally got it together a little bit, but still, I made too many mistakes on the greens.“Six three putts, I don’t think I’ve ever done that. I just have to clean up my mess on the greens and be ready for Thursday.”Woods is qualified to play in the WGC event because he finished among the top 30 in last season’s FedEx Cup standings.
