Wayne Webb, a 15-time Professional Bowling Association champion, led a field of five who advanced today to the final round of the $130,000 Fair Lanes PBA Open at Fair Lanes Woodlawn. The finals will begin Saturday at 3 p.m. (WJZ-TV-13).

Webb, a 27-year-old Indianapolis native who won this event in 1981 as well as last week's event in Milwaukee, began the evening match play in 13th place, but came on strong and finished with 9,669 points. Henry Gonzalez of Colorado Springs (9,617), Mark Williams of Beaumont, Tex. (9,589), Bob Handley of Pompano Beach, Fla. (9,582) and Charlie Tapp of St. Paul (9,549) also advanced.

"I just got my act together," said Webb, "I made mistakes in crucial situations but everything worked out. I feel good right now. I'm trying harder. For some reason, I bowl good on the East Coast."

Handley, 32, whose last victory was in Houston in 1983, began the evening in fourth place but quickly moved into the lead after his second game against Gonzalez, bowling 223. Handley remained in first place until Webb moved ahead in his fifth game against Bill Spigner, which he won, 234-167. Then, in the position round, in which the last game is between the first- and second-place bowlers, Webb scored 207 to keep first place. Handley's 201 dropped him to fourth.

"At times I did good, at times bad," said Handley, a three-time titlist. "I felt I had a good chance after the second game, but I kept making a bad shot now and then."

Going into the position round, Sam Maccorone of Glassboro, N.J., went head to head with Williams with a chance to advance to Saturday's final round. But Williams bowled 223 to move from fifth to third place and Maccarone remained in sixth (the alternate spot) with a 193. Gonzalez bowled 224 against Tapp to advance from third to second place.

"Nobody will be favored (Saturday)," said Webb. "They're all tough, particularly under these (final round) conditions."
