Castro, Spieth share lead at suspended AT&T National

Roberto Castro carded a 2-under 69 before play was suspended for rain on Friday to maintain a share of the lead at the AT&T National.

Jordan Spieth fired a 5-under 66 during his second round to meet Castro atop the leaderboard at 7-under-par 135.

"It was a great ball-striking day and, honestly, it came down to how well I was hitting my driver," said Spieth. "I felt comfortable working the ball both ways and I found a little groove when I was teeing the ball up. From there I had a lot of great opportunities to attack pins, play it on the safe side and it worked out for me."

D.H. Lee also shot a 66 to grab a share of third place with Andres Romero at 5-under.

Romero is 4-under through 13 holes and will finish his second round at Congressional Country Club's Blue Course when play resumes at 7:00 a.m. ET Saturday.

Cameron Tringale (67) and James Driscoll (69) are tied for fifth at 4-under 138.

Castro entered the day with a 2-stroke lead, but lost some of that cushion at the third with a 2-putt bogey after hitting his tee shot into a fairway bunker.

After parring the next four holes, he rolled in 25-foot birdie putt at the eighth to again reach 5-under and followed that with a short birdie putt at the ninth.

He would then par his next six holes before converting another short birdie effort at the 16th to move to 7-under. He parred his final two holes to stay there.

"It feels good to play two rounds under par," Castro said. "It's a very hard golf course."

Spieth, meanwhile, used a blistering front nine to meet Castro in a share of the lead.

His outward 31 began with a 26-foot birdie putt at the first, and he later converted back-to-back birdie efforts at the fifth and sixth to move to 5- under for the tournament.

Spieth then capped another pair of gains at the ninth with an 11-foot putt to grab a share of the lead.

He would par his next nine holes to remain tied atop the leaderboard.

Romero cruised through his outward nine with birdies at Nos. 3, 6 and 8 to make the turn at 4-under before tripping to a bogey at the 11th.

But he bounced right back with back-to-back birdies at the 12th and 13th to pull within two strokes of the lead prior to play being suspended.
