John Deere Classic leader Luke List was delighted to be back out on the course and enjoying his golf after a tough time of things in his personal life.

List's newborn son Harrison was in intensive care after contracting a respiratory virus but is thankfully now home and recovering.

However, it was a difficult few weeks for List, who shot a 63 on Friday tomove a shot clear of joint overnight leader Sebastian Munoz.

"It was tough, but it's been amazing to come back," he said.

"Everyone has been asking and praying and thinking about us, so it's kind of cool.

"It's a big family out here, and it's nice to know that you've got everyone's support when it's not going great."

List's card showed eight birdies as he moved to 13 under for the tournament, one clear of Munoz after the Colombian's 67.

A group of seven players sit on 11 under in a tightly congested leaderboard.
