American world number 99 Cameron Tringale backed up his strong opening day at the Texas Open with a three-under 69 on Friday to take a two-shot lead into the weekend.

Tringale, 33, has never claimed a PGA Tour victory but has set himself up perfectly, two shots ahead of three-time major winner Jordan Spieth and Matt Wallace.

The 12-year veteran bogeyed his opening two holes on Friday after sitting equal second after day one but responded with five straight birdies in his fourth to eighth holes.

"I just hit a lot of really good iron shots to those holes," Tringale said. “I think my furthest putt was 4 feet, so just good approaches to the green... I took advantage most of the time.”

First day leader Camilo Villegas slipped five shots back after shooting a 76, while Texas native Spieth looms after putting together two good days as he chases his first title since 2017.

The former world number one shot a two-under 70, although he started strong with two birdies including an approach within 10 feet on the first before slowing up.

"I thought the start was key for me, and I got off to a great start," Spieth said. "I put some really good swings on the ball after kind of being a little sloppy at the end of yesterday’s round."

He added: "I’m really pleased with where things are at, but they’re not where I want them to be at."

Equal second Wallace is another yet to win on the PGA Tour but he moved into contention after a four-under 68 which included no bogeys.

"Whenever you go bogey free, whatever golf course it is, it’s nice, but especially here," Wallace said.

A group of four players are two shots behind Spieth and Wallace, with Kevin Stadler, Kyle Stanley, Erik van Rooyen and Brandt Snedeker who had a birdie-birdie finish.

Matt Kuchar and Villegas are among the next group of six at four-under, while Charley Hoffman shot a day two best 66 to be tied at three-under.

Five-time major winner Phil Mickelson was unable to recover from his horror first round which was ruined by taking a 10 on the 18th and missed the cut.
