Collin Morikawa soars to top of U.S. Open leaderboard with 4-under 66; tied with Joel Dahmen after 2 rounds

BROOKLINE, Mass. — The storms dodged Brookline, and the stars began to emerge Friday in the U.S. Open.

Collin Morikawa showed signs of emerging from pedestrian play at just the right time, matching the low score of the championship with a 4-under 66 for a share of the 36-hole lead with Joel Dahmen and a shot at a third straight year winning a major.

He had plenty of company at The Country Club, one player in clear view.

Defending champion Jon Rahm played with Morikawa and did his best to keep pace with an eagle and a series of big par putts that felt just as valuable. Rahm had a 67 and was one shot behind in a group that included Rory McIlroy.

Not to be overlooked was Masters champion Scottie Scheffler, who chipped in from thick rough short of the par-5 14th green for an eagle that brought the Texan back into the mix with a 67. He was two shots behind.

«It's the U.S. Open. No one has taken it deep so far and kind of run away,» Morikawa said. «The last few days is a huge confidence booster for me heading into this weekend, and hopefully we can kind of make some separation somehow.»

Morikawa, Rahm and Scheffler have combined to win four of the last nine majors. And then there's McIlroy, who has four majors by himself, but none since 2014.

«I think it's great for the game of golf that the highest ranked players and the best players are up there, especially in the tournament where truly the best player ends up winning,» Rahm said.

The idea of the U.S. Open is to identify the best players. Some of them require some introductions to major championship contention on the weekend.

Start with Dahmen, the cancer survivor and everyman who will never be accused of taking himself too seriously, even if he takes his game seriously. He
