In the wind and then a brief rain shower, Mark Calcavecchia took dead aim Saturday and wound up with the lead after the third round of the Honda Classic in Coral Springs, Fla.

Calcavecchia made four birdies on the front nine to surge to the front of the pack and held on for a 4-under-par 68, giving him 205 and a one-stroke lead over Vijay Singh, who had a bogey-free 68."I know I'm going to make some birdies," Calcavecchia said. "It's just a question of how many."

Tommy Tolles had a 65 for the low round of an ever-changing day and was tied for third with Kevin Sutherland at 8-under 208.

Colin Montgomerie, looking for his first win in his 46th PGA Tour start, was in a large group at 207 that included defending champion Stuart Appleby and Lee Janzen.

Jeff Maggert, who led after each of the first two rounds and is winless since 1993, got mired in one bunker after another. He made five bogeys on the back nine and finished with a 76, six strokes off the lead.

After opening with strong winds and then alarming calm, the third round of the TPC at Heron Bay had a little bit of everything. Calcavecchia stuck to his game plan to firing at every pin, and paid off.

He holed a 25-footer for birdie on the second hold then squeezed 5-irons into about 12 feet for birdies at the par-3 fifth hole and No. 7, a short par-4.

WELCH'S-CIRCLE K CHAMPIONSHIP: At Tucson, Ariz., Helen Alfredsson took advantage of a two-shot swing late in the round and shot a 2-under-par 70 Saturday to maintain her lead in the Welch's-Circle K Championship.

Alfredsson's 54-hole score of 14-under 202 was enough for a one-shot edge on Chris Johnson, a Tucson resident who won her hometown tournament in 1984 and 1991.

Johnson shot a low round of 67 but was prevented from sharing the lead by a bogey on the next-to-last hole.

Dana Dormann, 1995 winner Dottie Pepper and Tina Barrett, who finished second to Donna Andrews last year, were four strokes off the lead.

TOSHIBA SENIOR CLASSIC: At Newport Beach, Calif., Hubert Green - winless since the 1985 PGA Championship - shot a 5-under-par 66 to take a one-stroke lead Saturday after two rounds at the Toshiba Senior PGA Classic.

Green stood 9-under at 133 with 18 holes remaining at the Newport Beach Country Club.

Jim Albus, the leading candidate for the Senior Tour's Comeback Player of the Year award, shot a 65 to move into second place. Mike McCullough had a 70 for a 36-hole total of 136 and sole possession of third place.

Eight players were tied at 5-under.
