Jack Nicklaus bogeyed the final two holes yesterday, but leads Lee Trevino and Terry Dill by a stroke midway through the Senior Tournament Players Championship in Dearborn, Mich.

Nicklaus shot four-under-par 68 for a total of 11-under 133 on the 6,665-yard Dearborn Country Club course. Trevino also shot 68; Dill posted his second straight 67.

Gary Player and Ben Smith, the first-round co-leader with Nicklaus, were two shots back at 135.

Nicklaus birdied the 15th to go 13 under, but bogeyed the 17th to tie with Trevino. Both hit trouble on 18.

Trevino, the leading money-winner on the Senior PGA Tour, found a water hazard and took a double-bogey six. Nicklaus then bogeyed the 18th.

They are paired for today's third round of a rare 72-hole seniors event.
