Thomas, who shared the overnight lead with Scott Brown, fell behind when he had double bogey on the 550-yard par-5 No. 3 hole. "I just kept telling myself it was a bad golf swing," Thomas said. "It wasnít a mental error or wasnít a wrong judgment that we made but just a bad golf swing at a pretty bad time, but I knew you are going make bogeys out here" Sunday.Thomas regained the lead and looked set for the win in regulation until he bogeyed No. 17, a 195-yard par 3 hole. But he made amends with birdie at the last to finish the round at par 72 and join Leishman in the playoff. "I really played some great golf after the third hole, but itís just such a long day with these conditions," Thomas said. Thomas said he is looking forward to some time off after his breakout season. "Iím so excited to not do anything," he said. "I officially have nothing left in the tank at this moment." Leishman, who ended a five-year drought on tour when he won the Arnold Palmer Invitational at Bay Hill in March, then added the BMW Championship in September, looked to have slipped out of contention when he bogeyed Nos. 5, 7 and 8 to tumble down the leaderboard. But he birdied Nos. 9, 12 and 14 to join Thomas at 9 under.
