STATELINE, Nev. -- Former tennis player Mardy Fish had a 28-point round Saturday to take a two-point lead over actor Jack Wagner in the American Century Championship celebrity golf tournament.

Fish shot a 3-under 69, making seven birdies and four bogeys at Edgewood Tahoe to reach 50 points in the modified Stableford event. Players receive six points for eagle, three for birdie, one for par, none for bogey and minus-two for double-bogey or worse.

"I was (behind) quite a bit (at the start) today," said Fish, a six-time winner on the ATP Tour. "And there's a lot of really good players at the top as well. I'm in a really good position to hopefully play well tomorrow and see where we are."

Fish is trying to become the first left-hander to win the event. He won the Diamond Resorts Invitational celebrity tournament in Florida this year.

Wagner, the first-round leader, had a 21-point day. He won in 2006 and 2011.

Defending champion Mark Mulder and Mike Modano were tied for third at 45.

Entertainer Justin Timberlake was tied for 24th with 20 points, and NBA MVP Stephen Curry was tied for 34th with 14 points. Larry the Cable Guy and Charles Barkley held the last two spots in the field. Larry the Cable Guy had minus-46 points and Barkley minus-68.
