Hayward, CA (SportsNetwork.com) - Blayne Barber was one of five players to card a 7-under 63 on Thursday and claim a share of the Stonebrae Championship lead before play was suspended by darkness.

Tyler Weworski, Hugo Leon, Cameron Wilson, Scott Pinckney, Timothy O'Neal and Josh Broadaway were tied for sixth place at TPC Stonebrae at 6-under 64.

"My favorite club in the bag is my driver and it's been my absolute worst club this year," said Weworski, who has missed eight straight cuts heading into this event. "I knew coming into this week I was starting to hit it good. I got to this week and saw this course was a bit of a bomber's paradise, so I figured it would be good."

Adam Hadwin, Zack Sucher and Andrew Putnam, all of whom have won this season, were among a group of nine players to shoot a 5-under 65 and share 12th place.

Baker later closed his round with back-to-back birdies at the eighth and ninth to claim the clubhouse lead at 7-under.

"I just haven't put four days together," said Baker. "I've made several cuts, but I've been struggling on the greens and anytime you do that it just leaks into the rest of your game. It makes the whole game harder."

Blaum countered an early bogey at the 13th with birdies at the 14th and 16th around an eagle at the 15th to reach 3-under.

Three straight birdies from the second pulled him within a shot of Baker, and Blaum claimed a share of the lead with a birdie at the eighth, He parred the ninth to end there.
