Wyndham Clark builds 4-shot U.S. Open lead with lowest 36-hole score at Shinnecock

Wyndham Clark rapped his 35-foot putt and immediately rose from his crouch, worried it might have too much pace down the slope on the 18th green Friday in the U.S. Open.

It curled into the side of the cup for a final birdie and another standard he set in Southampton, N.Y.

It wasn't his best putt, just another birdie for a 1-under 69, and it summed up his week.

Clark doesn't feel he is playing his best, but he's four shots ahead going into the weekend with the lowest 36-hole score -- 7-under 133 -- for a U.S. Open at fearsome Shinnecock Hills

"Hopefully, I can bring my A-game on the weekend," Clark said.

His four-shot lead was the largest at a U.S. Open through 36 holes since Dustin Johnson led by four at Shinnecock Hills the last time it was here in 2018. That didn't end well for Johnson when the USGA lost control of the frightening greens on Saturday.

What now?

The USGA promised it wouldn't let the course get away like it did in the third round in 2018 and the final round in 2004, when the average score on the last day was 78.7 and no one broke par. Shinnecock began to bake under a warm sun late Friday afternoon, with more of the same -- and stronger wind -- in the forecast.

"The golf course can change pretty quickly, and so a lot of that depends on do they want to water the greens, how fast they want to get them, where is the wind direction coming from, can they get them much quicker," said Scottie Scheffler, who kept the career Grand Slam in play.

Scheffler ended his drought of 10 straight U.S. rounds without breaking par with a steady diet of fairways and greens for a 68, leaving him seven shots behind.

"We'll see what they want to do," Scheffler said. "My job is to out there and play
