Scottie Scheffler's record streak ends as Tony Finau takes lead at Houston Open

Starting Friday's second round on the back nine, Finau began steadily, picking up three birdies before a bogey on the par four first hole threatened to derail his momentum.

The American responded with a flurry of birdies and an eagle to head into the weekend two shots in front on nine under.

"I've played some nice golf the first couple days and the game's in a good place," Finau said. "Just don't overthink it, get some rest, be properly prepared, properly rested for the weekend."

At the par-3 ninth, Finau narrowly rolled a 16-foot birdie putt past the hole to miss out on 61.

"I knew what it was for - 61 would have been my lowest on the tour and the course record," Finau said. "I knew I was going to give it a run. I wasn't going to leave it short.

"I hit a good putt and it was barely too low. I thought I hit it hard enough for it to stay on the line."

Argentina's Alejandro Tosti is in second spot, following an opening round 66 with a three under 67.

Scheffler, who is chasing a third straight PGA Tour victory, carded an even par 70 after a stumble at the last hole of the day, ending a modern-era record for consecutive rounds under par at 28.

The 27-year-old three-putted from six feet for a double-bogey six on the 18th that saw his streak come to an end.

"I'm obviously a touch frustrated with how I finished, but overall I'm still in the middle of the tournament," Scheffler said afterward.

He is among a group of six players on five under with England's Aaron Rai and David Skinns a shot further back.
