SAN ANTONIO -- Mark Calcavecchia shot a 5-under 67 on Friday to take a two-stroke lead over Kenny Perry in the suspended first round of the Champions Tour's AT&T Championship.
Thirty-three of the 80 players were unable to complete the round because of darkness. The round started on time, but play was delayed 3 hours, 18 minutes when a rain storm blew through with lightning and strong wind gusts. The temperature dropped as low as 48 degrees.
"It definitely was the equivalent of shooting 62 or 63," Calcavecchia said, noting the difficult conditions. "One of my best rounds of the year. I hit almost every fairway and 16 greens."
Perry was 3 under with three holes left when play was suspended on TPC San Antonio's Canyons Course.
Tom Kite shot a 70, and Willie Wood also was 2 under with a hole left.
Calcavecchia won the Montreal Championship in June for his second title on the 50-and-over tour. He finished second last year, seven strokes behind Fred Couples.
On Friday, Calcavecchia had five birdies and a bogey on the back nine.
"Calc has gone crazy here on us," said Haas, who shot a 72. "It feels like he's shooting 59 out there. I'm certainly very pleased with even par today. If a gust hits (a ball on the putting green), it could break another 4, 5, 6 inches."
Calcavecchia had surgery on his right hand to repair ligament damage near his ring finger seven weeks ago.
"The hand is coming around," he said. "Now I've got to get it to where I can go bowling with it again."
The tournament is the final full-field end of the year. The top 30 on the money list will qualify for the Charles Schwab Cup Championship next week at Desert Mountain in Scottsdale, Ariz. Mark McNulty is 30th, $32,506 ahead of Kite. McNulty opened with a 78.
Bernard Langer leads the Charles Schwab Cup standings, 111 points ahead of Tom Lehman. The winner will get a $1 million annuity. Lehman was 1 over with three holes left, and Langer was 2 over with two to go.
Couples is sidelined by back problems.
