RENO, Nev. -- Rookie Collin Morikawa birdied four of the last five holes, including each of the final three, to clip Troy Merritt and capture the Barracuda Championship on Sunday, July 28, at Montreux Golf & Country Club in Reno.

Morikawa scored plus-14 in the event's Modified Stableford scoring system, which awards two points for a birdie (five for an eagle) and minus-1 point for a bogey (minus-3 for double bogey or worse), with no points for a par.

He finished at plus-47 for the tournament, three points ahead of Merritt, who cooled off from a plus-18 on Saturday to score plus-7.

The 22-year-old Morikawa earned a temporary PGA Tour exemption through the rest of 2019 with a tie for second at the 3M Open last month, just his third event as a pro. He threatened again a week later, tying for fourth at the John Deere Classic, before claiming his first win on Sunday.

"To be in that position is what I've wanted to do all summer," Morikawa said afterward, per Golf Channel. "To finally have the lead, it was out of my control. You don't always want that, but it was something really special to finally get the win.

"I think the gates are open. I've been knocking on the door the past month or so, and the game's been feeling good."

Playing in the penultimate group, Morikawa sank 7- and 10-foot birdie putts at Nos. 14 and 16, respectively, then found the center of the cup with a speedy 29-footer at the 17th to take the outright lead. Merritt, in the final pairing, could only par the last three holes, making Morikawa's up-and-down birdie at the par-5 18th just a cherry on top of victory.

Merritt finished with four birdies and one bogey in his round, after tallying four birdies and two eagles on Saturday.

John Chin (who scored plus-9 on Sunday) and Robert Streb (plus-5) tied for third at plus-40, while Bronson Burgoon charged into fifth place at plus-39 with a round of plus-15.

John Daly, allowed to ride in a cart in the event because of osteoarthritis in his right knee, had his worst round of the tournament, scoring minus-4. He finished at plus-10 overall in 69th place.

The alternate-field event ran concurrently with the World Golf Championships-FedEx St. Jude Invitational in Memphis, Tenn., which was won by world No. 1 Brooks Koepka
