AUGUSTA, Ga. — Making a double bogey at the par-5 second hole at Augusta National isn’t the ideal way to start the second round of the Masters. But Brooks Koepka hasn’t let anyone see him sweat before, so why start now?

Koepka recovered from the early stumble to shoot a 1-under 71 on Friday to share the lead at 7-under heading into the third round of the year’s first major championship. The double-bogey at the second hole was part of a front nine where Koepka also had three birdies and two bogeys. Two birdies on the back nine at the par-5 15th and the par-4 18th kept him under par for the day.

“I’m proud of myself for the way I hung in there,” Koepka said. “My bounce-back stats are pretty good. I think part of that is just because of my temperament. I never get too down.”

Koepka shot 66 in the opening round on Thursday and looked like he was off to a good start with a birdie at the first on Friday. But then he hit his drive at the second hole into the pine straw on the left before his second shot hit a tree and bounced into a hazard. After a drop, he punched out, then hit the ball on the green where he two-putted for a seven.

“You’re going to be tested in a major championship one way or another,” Koepka said. “I’ve just got to deal with whatever comes. I hit a bad shot, just got to suck it up and just keep going on.”

Koepka needed the birdie at the 18th to join a group of five sharing the lead at 7-under. After missing a few makeable putts during his round, Koepka was determined to make the 15-foot downhill putt for his 11th birdie of the tournament.

“I just told myself I wasn’t going to miss it right like the rest of them,” Koepka said. “It dribbled in there on the left edge at the last second. It’s always nice to finish on a birdie and feel a little bit better about the round.”

Koepka, the back-to-back U.S. Open champion and defending PGA champ, is looking to win his fourth major in less than two years.

“I know some people don’t think I’m mentally tough or tough in general, but I think I am,” he said. “I think I’ve proven that with three trophies. I feel like no matter how things are going whether they are going really well or really poorly out there, I can grind it out, especially during a major. I know to just hang in there because there’s always something around the corner.”
