MADISON, Miss. — Billy Horschel was one of the few players who walked off steamy Annandale Golf Course in a good mood on Friday afternoon. While others looked haggard after broiling in Mississippi's brutal summer weather, Horschel could have gone another 18.

"Playing the way I am," Horschel said, "I don't want to go home."

It's hard to blame him. The 25-year-old shot a 9-under 63 in the second round of the True South Classic to take a one-stroke lead into the weekend at waterlogged Annandale. It was his best round on the PGA Tour.

Horschel had a 13-under 131 total. Matt Bettencourt shot a 6-under 66 on Friday and was one stroke back. About half the field was forced to finish the second round on Saturday.

Former UW Husky Richard H. Lee was at 3 under overall and was not projected to make the cut.

Note

• Actor Jack Wagner and former pitcher Mark Mulder shared the lead after the first round of the American Century Celebrity Golf Championship at Lake Tahoe in Stateline, Nev. NFL kicker Ryan Longwell was third, and Dallas Cowboys quarterback Tony Romo and hockey Hall-of-Famer Brett Hull were tied for fourth.
