Tom Lehman was a surprise presence towards the top of the Charles Schwab Challenge leaderboard when the PGA Tour season resumed on Thursday.

There were no spectators at Colonial Country Club in Fort Worth, Texas as some of the world's best players looked to make up for three inactive months after the season was suspended due to the coronavirus pandemic.

A strong field had to abide by social distancing measures on their return to competitive action, but Justin Rose was certainly not restricted as he set the pace with a seven-under 63.

Jhonattan Vegas and Abraham Ancer were just a shot adrift of early leader Rose, while Lehman also looked anything but rusty, starting with a 65 in a tournament he won back in 1995.

There was just one bogey in an eye-catching opening round from the 1996 Open champion, who became the oldest player to shoot 65 or better on the PGA Tour in the last 40 years at the age of 61.

Lehman said: "Do I feel like I'm capable of shooting a 65 out here at Colonial? Well, for certain I do. Did I expect to do it today? Well, I would be probably lying if I said I fully expected to play and shoot such a low score. But I did expect to play well."

There was a poignant moment when those on and off the course stopped to observe a moment of silence and reflection at 8.46am for George Floyd, who died last month while in police custody in Minneapolis.

Rory McIlroy was among those to go out later in the day and the world number one was two under through 13 holes.
