Collin Morikawa entered Sunday's final round at the Zozo Championship in Chiba, Japan, two shots behind leader Justin Suh.
When it was all over, Morikawa turned the deficit into a six-stroke victory, shooting a 63 at the Accordia Golf Narashino Country Club to win his first title since 2021.
"Would have had to play, as it turns out, really well today to win," said Beau Hossler, whose 70 was good enough for a tie with Eric Cole for second place at 8-under 272 for the tournament. "And that's what champions do, right? Collin's a proven champion on the biggest stages, so kudos to him."
Morikawa's Sunday round started with four birdies on the front nine. Suh, playing in the group behind Morikawa, countered with three bogeys, and by the time he made the turn, Morikawa had vaulted into the lead.
Morikawa's bogey-free 63 was the lowest final-round score to win the Zozo in tournament history. His 14-under finish and six-stroke win was the biggest margin of victory in tournament history, besting Hideki Matsuyama's five-stroke win in 2021.
"The game felt really good," Morikawa said. "... Everything just kind of clicked, and we were able to not make any errors really, make the par putts when needed, and it was nice to finish off that front nine with a birdie on 8 and 9."
Morikawa's last PGA Tour win came at The Open Championship in 2021. Sunday's win was his first overall since the 2021 DP World Tour Championship.
"It feels incredible," he said of his sixth PGA Tour title. "Every win's so different, and every experience, whether it's winning or losing, you learn a lot, but this one just meant the world."
Cole and Hossler entered the round tied for second at 8-under and both shot par 70 on Sunday to finish in the same spot. .
Robby Shelton fired his second 65 of the tournament -- he also opened with a 65 -- to move into a fourth-place tie with Japan's Ryo Ishikawa (67). Americans took four of the first five places.
Another American, Suh, held his first-ever 54-hole lead but struggled throughout the round on Sunday with six bogeys and only two birdies. His 74 left him at 5-under for the tournament and in a tie for 10th.
Morikawa pocketed $1.53 million on Sunday. Perhaps more importantly, he walked away with both a sense of satisfaction and relief after the two-year winless drought.
"It feels so good, I can't even explain it," Morikawa said of his sixth PGA Tour win. "I knew I was going to get here at some point. It's like getting your first win, your first major."
