Matt Kuchar got on such a roll Saturday even he wasn’t sure what his final score was.

“I blanked out,” Kuchar said. “I completely have no idea.”

OK, maybe that’s not entirely true. There’s not a golf course out there that the 20th-ranked player in the world wouldn’t know his score after every hole.

But even the mild-mannered Kuchar was in a joking mood following his career-best 8-under 62 at Waialae Country Club on Saturday that vaulted him from the cut line into a tie for sixth place heading into the final round of the Sony Open in Hawaii.

The crowd gathered at each green on the front nine had plenty of opportunities to yell, “Kuuuucchhh,” as Kuchar birdied his last six holes to shoot 29 on the front after starting on the back.

His 8 under bettered Friday rounds of 63 he shot in 2013 and ’15 on the way to four consecutive top-10 finishes at the Sony Open heading into this week.

“This is such a course where if you’re playing good, you can make birdies, but if you’re just off, you can be really struggling to make pars,” Kuchar said. “It’s a really good test of golf and why this is always one of my favorites golf courses (to play) every year.”

Kuchar’s string of top-10s was the furthest thing from his mind after a surprising opening round 1-over 71. He followed that up with a double on No. 2 and a bogey on No. 3 early Friday to drop all the way to 4 over.

It took an eagle and five birdies, including one on No. 18, just to make it to the weekend, but two bogeys in his first seven holes Saturday kept him well back of the lead.

Kuchar was 10 shots behind co-leaders Brandt Snedeker and Zac Blair when he began his run, sinking a 30-footer for birdie on the par-4 fourth.

He had only one birdie putt longer than 7 feet the rest of the way as he played flawless golf, putting his drives in the fairway and nailing his irons close to the pin.

“The front side can play tough, but I really got it going and kept hitting inside 6 to 10 feet,” Kuchar said. “It was hard to believe I birdied the last six. It was a good stretch.”

Kuchar responded well to making it to the weekend. He’s only missed one cut in his past 43 PGA events — The Players Championship in 2015 — and had been over par only twice in his past 19 rounds at Waialae.

He said surviving the cut, especially after falling behind as many as six shots on Friday, geared him up for Saturday’s low score.

“I played those last 15 holes in 7 under (on Friday), so to do that I felt like my game was going in the right direction,” Kuchar said. “I was really excited to turn a bad start into a good round.”

Kuchar will open today’s final round with only five golfers in front of him, but trails the co-leaders by five.

It’s not an impossible feat to pull off. He expects someone will post a low score early and put pressure on the guys at the top.

“When the weather is like it has been, you can (go) low,” Kuchar said. “I’m thrilled to put a ground round together and go forward with a chance.”
