NAPA — Bryson DeChambeau hasn’t had much chance to get familiar with his wedge after changing to a graphite shaft this week. The former Clovis East High School standout certainly looked comfortable enough Friday as he attacked pin after pin to surge up the leaderboard at the Safeway Open.

DeChambeau shot a bogey-free 8-under 64 on Friday to take a two-shot lead in the Safeway Open.

DeChambeau had a 12-under 132 total at Silverado Country Club. The 26-year-old matched two others for the best round of the day and was in line to extend his lead, but left a 20-foot eagle putt short on No. 18.

“It’s always fun to come out and play to the potential you know you can,” DeChambeau said. “The greens got a little bumpy this afternoon but they’re still rolling nice enough to make some putts. I was able to control my line, control my speed and have a couple of them drop in.”

DeChambeau missed the cut at the season-opening event at The Greenbrier, didn’t play in last week’s Sanderson Farms Championship and got off to a slow start this week with an opening-round 68 that left him four shots back.

After beginning the second round with four consecutive pars, DeChambeau birdied No. 5, sank a 35-footer for birdie on No. 6, then had a tap in for another birdie on No. 8. He opened the back nine with three straight birdies, made another birdie on No. 14 then closed with a final birdie on 18.

“I knew if I could go work on my swing like I did yesterday and come out and feel comfortable like I did today, I’d come out and shoot a low number,” DeChambeau said.

Watney’s Hot Putter Has Him Close Behind

Nick Watney was second after a 65. Watney needed just 22 putts to complete his round and stay within range of DeChambeau.

″(The greens) are getting a little bit crispy right now, but they rolled pretty pure for me,” Watney said.

Justin Thomas made nine birdies and matched DeChambeau with a 64 that left him tied with Nick Taylor (66), Dylan Frittelli (65), Adam Long (68) and Cameron Champ (68) at 9 under.

First-round leaders Adam Scott and Andrew Landry tumbled down the leaderboard.

Scott struggled off the tee most of the afternoon and shot a 73 to fall into tie for 14th at 6 under. Landry shot 74 and drop to 5 under.

Mickelson, Romo Miss Cut

A few big names won’t be playing over the weekend.

Phil Mickelson shot 69 but was doomed by an opening 75 that included a quadruple bogey. Defending champion Kevin Tway bogeyed the final hole for a 72 to miss the cut by a stroke.

“The way I see it, there were eight par 5s and I’ve got to play those 4 to 6 under par to have a chance to win,” Mickelson said. “I played them 4 over. So there’s eight to 10 shots right there on simply the par 5s. It tells me that some areas are OK, but that’s the area that I’ve got to improve on.”

Tony Romo, the former NFL quarterback and current CBS analyst, also missed the cut, following an opening 70 with a 78. If he had made the cut, he planned to skip Sunday’s NFL broadcast in Chicago between the Bears and Minnesota Vikings.
