Playing in the second-to-last group, Howell had a chance to pull ahead on the final hole of regulation, but left his approach about 85 feet short and three-putted for par. His 5-foot birdie attempt veered left inches from the hole.
"Going into the day, I didn't really think that anybody had a chance apart from Scott," Howell said. "He's won before, he hits it long enough to take advantage of the par 5s. At 22 under, I figured if he shoots 6, 7 under, he's really not catchable. So, then to have a chance there in regulation, that's where I really would like that one back, that three-putt."
Making his second career PGA Tour start, Lingmerth hit his 4-iron approach left into the water in the playoff. He had an awkward stance with the ball above his feet.
"I didn't feel that comfortable over it, obviously," Lingmerth said.
Phil Mickelson had a 66 to tie for 37th at 17 under in his season debut.
"I was rusty starting the year," Mickelson said. "I had a great four days here where I can work on my game with perfect weather and wonderful golf courses, where I could build some momentum. Heading into San Diego, I feel a lot more confident."
