Jane Geddes, who won the U.S. Open championship in a playoff last week, shot a 4-under-par 68 today for a one-stroke victory over rookie Deb Richard in the LPGA Boston Five Classic.

Geddes birdied the last two holes and finished with a 72-hole total of 281 in outdueling Richard, hometown favorite Pat Bradley and rookie Ok-Hee Ku of Korea in the final round over Tara Ferncroft's 6,008-yard layout.

"I was relaxed. I wasn't as shaky as in the Open, and I felt I had a good chance to win," Geddes said.

Geddes' victory was worth $42,150. Richard, finishing second for the second time on the tour, won $25,437.

Richard, the 1985 NCAA runner-up from Florida, took the lead with a hole-in-one on the 150-yard 12th, but she lost the advantage with a bogey six on the 15th. After a birdie four on the 72nd hole, Richard had a final-round 71 for a 282 total.

Richard was tied for the lead entering the final round with Bradley, Cindy Hill and Val Skinner.

Bradley finished with a 72, one stroke behind Richard and in a tie for third with Ku, who had a final-round 71 despite a triple-bogey seven on the 14th hole. Ku came back with an eagle three on the next hole but still fell short.

Geddes beat Sally Little in an 18-hole playoff for the Open title Monday, her first victory in four years as a professional.

On the 17th hole, a 321-yard par-4, Geddes took a one-stroke lead with a birdie. Then she completed the round with a birdie four as the wind picked up and a thunderstorm approached the area.

Greater Grand Rapids Open: Jim Ferree sank a birdie putt on the first hole of a sudden-death playoff today to beat Chi Chi Rodriguez and Gene Littler and win the Senior PGA Tour tournament in Grand Rapids, Mich.

Ferree, 55, led the event by a stroke after Saturday's round. He shot 70 in the final round on the 6,453-yard Elks Country Club course for a 54-hole total of 9-under 204.

"I can't believe what a feeling it is," Ferree said. "Last week at Greenbrier , I shot a 66 and had a hole-in-one and lost on one of the most beautiful shots I could make, but this week fortune came along."

Littler missed a three-foot putt for par on the 18th, forcing the playoff.

All three players hit the 286-yard par-4 green in two shots. But Rodriguez sent his 8-foot birdie putt past the hole, and Littler left his short of the cup.

In winning his first senior title, Feree took home $37,500.

Hardee's Golf Classic: Mark Wiebe shot a 2-under-par 68 today for a one-stroke victory over Curt Byrum in the $400,000 tournament in Coal Valley, Ill.

Wiebe, who finished the 72 holes over the 6,514-yard Oakwood Country Club course with a 12-under-par 268 total, earned $72,000 with the title, his second in three years on the PGA Tour.

Byrum, in his first tour event of the season after he lost his PGA qualifying card last year, finished with a final-round 71. He won $43,200 and earned an exemption for the remainder of the 1986 PGA Tour.
