The Scottish No 1 is up nine spots to 41st in the latest standings after produding his best performance since finishing third in the Mayakoba Classic on the PGA Tour towards the end of last year.
“It was nice to remember what to do,” said Knox, who’d missed the cut in his three previous starts, including the Scottish Open and The Open.
The 31-year-old shot rounds of 66-71-68-68 for a seven-under-par total at Firestone Country Club in Akron, Ohio, where he finished alongside Rory McIlroy in joint-fifth.
Knox finished bogey-bogey to miss out on claiming third spot, but he had no complaints about a welcome return to form heading into the season’s final major, the US PGA Championship at Quail Hollow this week.
“I played very well at times, which was nice,” he added. “I haven’t seen that in a while. It was nice to get in the mix and feel the nerves again.
“I’m obviously a little disappointed finishing bogey‑bogey and just got a little unlucky on both holes. All in all, it was a pretty decent effort and I probably would have taken it at the start of the week.”

Hist club pro Tom Higson took the individual title at the second Gleneagles International Pro-Am.

“But winning on home turf at Gleneagles, which also happens to be one of the most prestigious golf venues in the world, made this victory particularly special.”
