Scottish No 1 Russell Knox got off to a promising start in the WGC-Bridgestone Invitational in Ohio, where Rory McIlroy declared himself satisfied with the first page of a new chapter in his career.
Knox carded a four-under 66 to sit second, a shot behind Belgian Thomas Pieters, with McIlroy, Open champion Jordan Spieth and Jon Rahm all in a group behind the Scot. Bidding for his second WGC title after winning the HSBC Champions in China in 2015, Knox looked back to his best as he signed for an eagle and four birdies at Firestone Country Club in Akron.
McIlroy was playing his first round since splitting from long-time caddie JP Fitzgerald, with his best friend Harry Diamond stepping in as a replacment.
“It was good,” McIlroy said of his first round in the event since winning it in 2014. “I’m taking a little bit more responsibility on myself.”
