Mark Calcavecchia shot a 5-under 67 Friday that had him in front when play was suspended in the opening round of the AT&T Championship. Thunderstorms and a cold wind blew across the TPC-San Antonio course Friday, forcing a delay of 3 hours, 15 minutes. There were 33 players from the 81-man field still on the course when darkness brought a stoppage of play. Calcavecchia, wearing a heavy sweater to fight off the first blast of winter-like weather in south Texas, birdied five holes on the back nine. Kenny Perry was alone in second at 3-under when play was stopped. He had three holes yet to play. Tom Kite, a native Texan who has never won in the state on either the PGA or Champions Tour, shot a 2-under 70. Willie Wood, who was also at 2-under with one hole left. David Frost, Mark Brooks, Peter Senior, Tommy Armour III and Mark Mouland were all at 1-under with more golf yet to play. They will resume the first round at 9:45 a.m. local time Friday. This is the next-to-last event on the Champions Tour this year and Bernhard Langer has the points lead in a bid to capture a $1 million annuity at the end of the season. Langer was 2-over with two holes to play, tied for 24th place. Defending champion Fred Couples is not playing this week after his chronic back problems once more became an issue.
