Bob Shearer birdied the last three holes today to tie Craig Stadler for the lead after two rounds of the $400,000 World Series of Golf.

Shearer started the day tied for the lead with Ray Floyd and Masahiro Kuramoto, but by the time he bogeyed the 15th hole, he trailed by five shots.

Then he rolled in birdie putts of 20 feet on the 16th, five feet on the 17th and two feet on the 18th.

"I couldn't have played those last holes any better," he said.

Stadler had to scramble all day.

"That's the worst I've driven the ball probably this year," he said. "I've got to try to find a shot that works. It's kind of scary."

One of his shots from the fairway--it was one of the few times he played from the short grass all day--found the cup for an eagle-2, but another one trickled into a pond and led to a double bogey-7.

Shearer, an Australian, shot his second straight one-under-par 69 for his 138 on the 7,173-yard Firestone Country Club course, while Stadler had 68.

Stadler made the turn in two-under 33 and was tied with Floyd. He went ahead by two strokes at the 370-yard 11th hole when his second shot, a pitching wedge from 95 yards, drew back into the cup for the eagle. Alwin, Beach Tie at 68 Special to The Washington Post
