Jon Rahm and Billy Hurley III shared Quicken Loans National lead, three strokes ahead of Vijay Singh going into the weekend at Congressional.
Playing together again Friday, Rahm and Hurley went shot-for-shot and to reach 11 under. Hurley, a Naval Academy graduate who lives in nearby Annapolis, shot a 6-under 65, and Rahm bogeyed the 18th hole for a 67 in his second round as a professional. He led Thursday after a 64.
"I couldn't be happier," Rahm said. "(Thursday) was a great round and after a great round usually it's hard to follow it. To play golf the way I did today, I'm really proud of myself."
Rahm and Hurley will play in the final group Saturday at Congressional, just behind Singh, who was alone at 8 under after a 66. Four-time major champion Ernie Els (69) was 7 under along with Webb Simpson (68), Bill Haas (69) and Harold Varner III (69).
While Els was disappointed with his play Friday, Singh turned in a 66 that was most memorable for his shot from the edge of the water on No. 18.
The 53-year-old Singh hasn't won on the PGA Tour since 2008. He's in position to become the oldest PGA Tour winner, but said he wasn't thinking about making that kind of history.
"It would be good to win," the three-time major champion said. "But it's only halfway, so I'll be focused on my game tomorrow and see what happens."
Singh looked to be in trouble on the 18th when he hit into the rough under a tree and then landed his approach shot just inches from the water. He rolled up his pants and waded in to hit the shot that dropped him to 8 under at Tiger Woods' annual tournament.
"I was unfortunate that it went that far in and fortunate that it stayed out," Singh said. "I kept sinking when I got in the water. I started out with just my foot in the water and then it started getting up to my ankles. The more I moved the deeper I went, so I kind of had to play a very safe shot. I got away with a bogey."
Sixth-ranked Rickie Fowler had just one bogey in his second round and was in the clubhouse two strokes back of Singh after shooting a 68. Fowler will end his streak of missing the cut at three.
"I was able to just kind of stay patient and give myself a lot of looks at birdie, which is always good," Fowler said. "Nice to have a tee time on the weekend.”
