Hunter Mahan hits his 133-yard approach shot to 12 feet on the par-4 18th hole and makes the birdie putt.
BETHESDA, Md. -- With temperatures soaring into triple digits at Congressional on Friday, it was Hunter Mahan who was the hottest player on the golf course.
Mahan birdied two of his final three holes to shoot the day’s best round, a 65, to get to 7 under and a two-shot lead after two rounds of the AT&T National.
Playing late in the day, Mahan, who finished second to Tiger Woods the last time this tournament was played at Congressional in 2009, seemed unaffected by the heat.
Mahan went out in 32 with birdies on three of his last four holes, then kept the momentum going on the back nine with six straight pars before a birdie on the par-5 16th and another on the par-4 18th.
“When the conditions and the weather comes into play, it's a whole other factor,” Mahan said. “I've got to stay mentally tough. Once your mind goes, the body is going to go with it. It's very important to be mentally strong. We've got two more days of this, so it's going to be important to take care of yourself every night and every day when you're out on the golf course, or it's going to cost you shots.”
Three others -- Brendon de Jonge, Jimmy Walker and Robert Garrigus -- are tied for second, while five others are another stroke back.
Just 17 players are under par after two rounds at Congressional, which has played over par each of the first two rounds.
One of them is Tiger Woods, who won the AT&T National the last time it was held here.
Woods shot 68 Friday and is 2 under heading to the weekend.
The cut line was 6 over -- the highest since the 2011 Honda Classic.
