Many of golf's biggest names are stepping up at golf's toughest tournament.
Collin Morikawa (-5), Rory McIlroy (-4) and Jon Rahm (-4) — with a combined seven majors between them — top the leaderboard at the U.S. Open, along with qualifier Joel Dahmen (-5), after two tough but not impossible days at The Country Club in Brookline. The city of Boston was still recovering from Thursday night's NBA Finals loss, but the course was welcoming, particularly in the afternoon. Most of the players at the top of the leaderboard won the favorable Thursday morning/Friday afternoon draw, with light winds and warm temperatures keeping the course playable.
