KAPALUA, Hawaii — No one in the winners-only field at Kapalua has been more successful on Monday than Patrick Reed.

Instead of honing his game in the minor leagues before earning a card, Reed tried to Monday qualify into PGA Tour events. He made it six times out of eight tries, an astounding rate of success. Only this day was different.

Reed didn’t get into a PGA Tour event on Monday. He won a PGA Tour event.

“I felt like this win was more like the Mondays, because not only was it Monday, it was 18 holes,” Reed said after his playoff victory over Jimmy Walker in the Hyundai Tournament of Champions. “It was pretty bunched, so you just had to go out and go low. And luckily, we were able to do that.”

He did his most important work at Kapalua over the final four holes in regulation, and it wasn’t exactly bunched up at the moment. In fact, Reed was thinking more about trying to finish second when he stood on the 15th tee four shots behind Walker.

“I thought my chances were slim,” Reed said. “So I was just thinking to myself, `Let’s try to birdie three of the last four and get ourselves a chance to secure second alone, and give ourselves a chance — just maybe.”

The 24-year-old Reed did better than that. He two-putted the par-5 15th for a birdie. In the final group behind him, Walker began losing his lead when a 4-iron off the tee at the reachable par-4 14th sailed right into a bunker and led to bogey. And then, Reed holed out with a wedge from 80 yards for eagle on the 16th.

Just like that, he was tied with Walker at 21-under.

He still had work left. Reed three-putted from 100 feet just off the 17th green, missing a 4-foot par putt to fall one shot behind. Again, he figured a birdie was mandatory to at least have a chance. He took care of that with a two-putt from 80 feet to close at 6-under 67.

Walker, tied for the lead with Hideki Matsuyama at the start of the final round, would take only one shot back — the 4-iron into the bunker on the 14th. From there, he caught it too cleanly and sailed the green, and when he missed a short par putt, he ended his streak of 32 straight holes without a bogey.
