Morikawa torches Muirfield Village with 1st-round 65 to lead by 1

Collin Morikawa carded a 7-under 65 on Thursday at the Workday Charity Open to hold a one-shot lead over Adam Hadwin after Round 1.

Morikawa torched Muirfield Village with his best ball-striking performance of his young career. He gained 1.6 strokes off the tee and another 3.6 strokes through approach shots on top of a solid day on the greens. His best shot of the day came from 245 yards on the par-5 fifth, which he put to three feet before rolling in the eagle putt.

"It was a really solid day," Morikawa said. "Got off to a good start with a lot of pars but I was hitting them pretty close, hitting my iron shots good, tee shots felt great, and I knew if I just kept that going I was going to make some birdies."

The 23-year-old is coming off the first missed cut of his professional career at the Travelers Championship. He lost in a playoff to Daniel Berger at the Charles Schwab Challenge, which was the PGA Tour's first event back after a three-month shutdown.

Hadwin held the clubhouse lead early Thursday. After an opening-hole bogey, the Canadian rattled off seven birdies for his eighth consecutive round in the 60s on the PGA Tour. He finished in a tie for fourth at last week's Rocket Mortgage Classic.

Here's how the top of the leaderboard stands after Day 1:

Justin Thomas and Patrick Reed posted matching rounds of 68 to sit three shots off the lead. The two Americans both missed the cut in their previous starts.

Jon Rahm (even), Rickie Fowler (even), and Brooks Koepka (2-over) all got off to slow starts in Round 1.

Round 2 begins at 6:45 a.m. ET on Friday. Here is the broadcast schedule for the remainder of the week at Muirfield Village.
