With the sun setting and temperatures cooling rapidly, Stephen Ames of Trinidad moved to 6 under par to take the lead early in the second round of the rain-delayed B.C. Open in Endicott, N.Y.

Ames overtook first-round co-leaders Peter Jacobsen and Bradley Hughes by fashioning a 4-under 68 in the first round, then carding birdies on two of the six holes he completed in the second round before darkness fell.

"It's tough. It makes for a long day," said Ames, who has played in only 12 tournaments this year because of visa problems and missed the cut in his last three. "And tomorrow is going to be another long day again because we're going to finish, make a cut, and go back out and play again."

Hughes and Jacobsen each shot 67s in their first and only round of the day. They were tied with Russ Cochran, who had completed six holes of the second round when play was halted.

Phil Mickelson, Lanny Wadkins, Chip Beck, defending B.C. Open champion Chris Perry and Brandt Jobe were another stroke back.

* SENIOR PGA: Alberto Giannone, a native of Argentina playing his first year on the Senior PGA Tour, shot an 8-under 64 and held a one-stroke lead over Bud Allin in the Bank One Championship in Dallas.

Giannone, who entered the tournament ranked 78th on the senior tour in putting, needed just 20 putts.

Tom Watson, who finished tied for 22nd in his senior debut in Indianapolis last week, had an opening 67 in his first event against the tour's big guns. Hale Irwin, Bruce Fleisher, Allen Doyle and Larry Nelson--the top four players on the money list--did not play last week. Watson fared better than all of them: Fleisher had a 69, Irwin and Doyle 71s and Nelson a 72.

* LPGA: Helen Alfredsson topped off a stellar 65 with an eagle on her last hole and held a two-shot lead over Catriona Matthew in the $650,000 Safeco Classic in Kent, Wash. Alfredsson's 7-under-par round gave her a two-day total of 134. Defending champ Annika Sorenstam shot a 70 for 141.

* EUROPE: Miguel Angel Jimenez warmed up for next week's Ryder Cup by firing a 7-under-par 64 and surging to a three-shot lead at the Lancome Trophy tournament in Saint-Nom La-Breteche, France.

England's Gary Evans, who didn't make the Ryder Cup team, was in second place after also carding 64. Jimenez's Ryder Cup teammates Colin Montgomerie, Europe's No. 1 player, and Jarmo Sandelin were among those tied at 136.
