Top-ranked golfer Brooks Koepka was immediately back in strong form after returning from injury at the Abu Dhabi HSBC Championship on Thursday.

Koepka carded a bogey-free 6-under 66 to tie for third place, two shots behind the leading duo of Renato Paratore and Shaun Norris.

Koepka hadn't played since October after aggravating a knee injury when he slipped on wet cement at the CJ Cup in South Korea. However, he showed no sign of rust as he made six birdies.

“The first day I picked up the club, same thing, felt like I hadn't left," Koepka said. “I've done it for years and years. You don't forget how to swing the golf club.”

Of his knee, he added: “It feels fine. It was a little sore last night, just did some treatment on it, that's expected.”

Koepka, who missed the Presidents Cup last month, is tied for third with Jason Scrivener.
