Kisner eventually emerged as the champion at 10 under to defeat Spieth, Rahm and Sean O'Hair by one stroke with a Sunday 66.
For Rahm, his incredible rookie season continues with his sixth top 10 in addition to his win at the Farmers Insurance Open. "Came out holing putts on one and two, so anything can happen from there".
After igniting the crowd with an up-and-down to save par on the final hole, Spieth stood on a chair near the scoring area to peer over the crowd at the 18th green. "I'd hit one green". "If I'd missed this cut ...", added Spieth, who missed cuts at the Byron Nelson and The Players Championship.
"I had my opportunity there on 17", Spieth said. "I hope that's the case".
Lowry had gone to the turn in 30 thanks to five birdies in six holes, including four in a row from the fourth, while overnight leader Dodt recovered from a bogey on the first by chipping in for a birdie on the third and picking up another shot on the next.
Masters champion Sergio Garcia and England's Paul Casey moved to within one shot of the leaders at the Dean & Deluca Invitational. It meant an early start in the third round for the Olympic champion, who fired four birdies and two bogeys in a third round of 70 to reach level par. "That kind of gets those juices flowing".
Playing in the final group, Simpson birdied the first two holes Saturday.
"I wanted to get to that 10 number standing on 18 tee". "But you've still got to hit the shots and I managed to do that today".
"I looked at the score a lot at the 12th and 13th holes - I didn't have a clue what I was going to shoot". "It was pretty frustrating". A bogey on the 11th was followed by a double on the par-three 14th, but the Australian had an encouraging finish, chipping in for birdie on the 17th hole and making another birdie on 18 to end up seven-under. Kisner hit a similar drive, and also saved par. Simpson had a 71 to finish fifth at 8 under.More news: Langer wins record ninth Champions Tour major

The 54-year-old Singh is 10 under par for the week on the par 5s at President Donald Trump's 7,100-yard course on the shores of the Potomac River. Trump, coming off a nine-day trip overseas, did not attend the final round.
Langer stayed close to Singh despite an off day by his standards.
Feng earned her first victory of the season and seventh of her career. Lizette Salas was the only other player to shoot a 65 on Friday at Travis Pointe Country Club.
"It was nice to bounce back with birdies on five and six, which is always a positive sign".
Rahm, 22, continued to enhance his profile as the game's next superstar with another stellar performance, breaking into the top 10 in the world rankings.
Rookie Park Sun-hyun, the second-round leader, trails Feng by three shots going into the final round.
