CARLSBAD, CALIF., JAN. 4 -- Tom Kite had a game plan -- throw a good round at Lanny Wadkins and make up some ground -- and executed it to perfection.

The only problem was it didn't work.

"I shoot five under and didn't move," Kite said after a 67 today kept him three shots back at the midpoint of the Tournament of Champions, the PGA Tour season opener.

Front-running Wadkins had a bogeyless 67 for a 132 total, 12 under par.

"He's playing good," Kite said. "But still, you don't expect to shoot 67 and not pick up anything."

Kite once was within a stroke of the lead, but Wadkins responded with approach shots that stopped at tap-in distance on two of the last four holes. His birdies on the 15th and 18th, which restored his three-shot lead, each required a putt of about two feet. "Really nothing exceptional," Wadkins said. "Just a good, solid round. The big thing was I didn't make any big mistakes."

Despite two days of rain at the event that brings together only the winners of tour titles from the previous season, Wadkins has one bogey in two rounds.

John Huston (67 today) and Chip Beck (69) share third at 137.

In a separate but simultaneous competition for 1990 winners from the Senior PGA Tour, Bruce Crampton took advantage of Lee Trevino's absence and built a five-stroke lead. Trevino, who dominated the over-50 set with seven titles and a record $1,190,518 in 1990 earnings, withdrew with back spasms.

"I'm playing great. I'm two shots out of the lead. I'm playing in my favorite tournament in the world. And I can't swing a club," said Trevino, who was unable to start second-round play.

He said the lower back spasms result from a muscle pull suffered "about ten days ago." Trevino said the injury is not serious and is not related to back surgery he had a decade ago. "I'll be back in ten days," he said.

Crampton birdied his last two holes for a 69 that put him at 5-under 139. First-round leader Frank Beard shot 75, including 41 on the back nine, and was second at par 144.
