Morikawa ready to take advantage at Muirfield Village
Collin Morikawa believes he can build on his lead at the Workday Charity Open after moving three shots clear of the field at the halfway point.
The American will start the weekend on 13-under-par after a second round of 66 in Ohio.
Morikawa followed an opening-round 65 with a six-under round, and he showed no signs of letting up, despite play being suspended twice for the threat of lightning.
Kevin Streelman's round-of-the-day 64 helped him move into a share of second alongside Justin Thomas, with the duo on 10-under after 36 holes.
Sam Burns and Japan's Hideki Matsuyama share fourth, while Viktor Hovland and Rory Sabbatini are a shot further back on eight-under.
Morikawa, now 29th in the world rankings, missed his first cut as a pro last time out at the Travelers Championship, but he has learnt his lesson.
The 23-year-old is making his debut at the course Jack Nicklaus built, and his game looks perfectly suited to the Ohio track.
Morikawa is looking to keep his game error-free and use the conditions to his advantage, and he believes his first setback last month has helped him improve.
He told the PGA Tour: "I had heard from a lot of people before, this course was going to suit a left-to-right shot, anyway. Obviously, Jack hit that, and I think it does. But I've been able to leave myself some really good numbers into approach shots. I've been keeping myself in the fairway for the most part, and that obviously helps.
"At the end of the day, you're out there to win tournaments. If you miss the cut, make it by whatever, you just want to learn from each week. And like I said, I learned a lot from those two days missing the cut than I have in a lot of events so far when I've been finishing whatever."
Morikawa is now 1.03 to win the tournament, with Thomas his nearest rival at odds of 15.00.
