Jim Gallagher rolled in an eight-footer for par on the first playoff hole and won the Greater Milwaukee Open yesterday when Ed Dougherty and Billy Mayfair missed putts to tie.

Gallagher, gaining his first tour victory, teed off first in the playoff on the par-3 No. 17 hole at Tuckaway Country Club in Franklin, Wis., and was the only one of the trio to reach the green. He two-putted for par and it was good enough for the $162,000 first-place prize.

Dougherty hit his tee shot into the bunker, chipped out and missed a putt from about eight feet. Mayfair, who had birdied 16 and 17 for a one-shot lead before bogeying the final hole of regulation, hit his tee shot past the green, chipped back past the hole and missed an eight-footer.

The three, each seeking to win for the first time, tied at 17-under 271 as Mayfair had a final-round 68 and Gallagher and Dougherty 66s. Ray Stewart, the leader through three rounds, missed the playoff when, like Mayfair, he bogeyed No. 18.

Senior PGA:

Mike Hill birdied the first hole of sudden death to beat Bruce Crampton for the $67,000 first prize in the GTE North Classic at Broadmoor Country Club in Indianapolis.

Hill's second shot on the 364-yard 16th hole landed three inches from the cup and he tapped in. Crampton's approach landed beyond the green and his third shot skidded past the cup, leaving him a long putt for par.

Hill got into the playoff by shooting a four-under 68 for a 54-hole total of 201, 15 under. He birdied the 482-yard 17th hole to tie Crampton, who shot a 66 and almost won on the 18th when his birdie try from the fringe stopped on the edge of the cup.

LPGA:

Defending champion Beth Daniel had a 69 and a tie with Martha Nause for the lead with eight-under-par 136 after two rounds of the LPGA Rail Charity Classic in Springfield, Ill. Nause shot 67, lowest round of the day.

Daniel, the LPGA's leading money winner, twice has won events back-to-back this year and is trying to do it again; last week she won the Northgate Classic.

European Masters:

Ronan Rafferty of Northern Ireland shot 66 and won the $885,000 event in Crans-sur-Sierre, Switzerland. His 72-hole, 21-under-par 267 gave him a two-stroke margin over John Bland of South Africa and the $147,000 first prize.

Rafferty, 26, started the day one shot behind Ove Sellberg of Sweden. Sellberg blew to a 77 for 277.
