Mark Calcavecchia fired a 5-under 67 on Friday to take the lead during the suspended first round of the AT&T Championship.
A 3-hour, 15-minute weather delay due to thunderstorms set play back on Friday and the whole field couldn't complete the first round before darkness set in at the TPC San Antonio.
The first round will resume at 10:45 a.m. ET Saturday, but the second round will begin with players in the same groups from the first round at 9:30 a.m. Saturday.
Kenny Perry is second at 3-under par, but the Kentucky native completed 15 holes of his opening round.
Tom Kite is in the clubhouse at 2-under 70 and he was joined in a share of third by Willie Wood, who only has his final hole of round one to finish Saturday morning.
Kite is in a tough spot this week. He is 31st on the Champions Tour money list and the top 30 advance to next week's season-ending Charles Schwab Cup Championship.
Kite trails Mark McNulty by $32,506, but there's hope. McNulty struggled to a 6-over 78 on Friday.
David Frost, Mark Brooks, Peter Senior, Tommy Armour III and Mark Mouland are all at 1-under par, but have yet to complete the first round.
Everyone will be chasing Calcavecchia, who opened with a birdie at the par-4 first, then parred his next eight holes. After the turn, Calcavecchia birdied three in a row from the 10th to vault into the lead at 4-under par.
After a par at the 13th, Calcavecchia, who finished second by seven shots last year, bogeyed the par-4 14th. He immediately atoned for the error with a birdie at the par-5 15th.
Calcavecchia, who won this year's Montreal Championship. birdied the 17th to get to 5-under and stayed at that number with a par at the last.
Gil Morgan, Jay Haas, Mark Wiebe and Tom Pernice, Jr. each posted rounds of even-par 72.
NOTES: Last year's winner, Fred Couples, is not on hand to defend his title as his balky back injury flared up once again...The tour's leading money winner, Bernhard Langer, is 2-over through 16 holes...Fred Funk, who won the Greater Hickory Classic two weeks ago, is also 2-over, but he played one less hole than Langer.
