LAKE ORION, Mich. — Lance Ten Broeck expected to make it to the weekend at the U.S. Senior Open.

The full-time caddie and part-time player, though, didn’t dream of being the second-round leader.

Ten Broeck shot a 68 on Friday, putting him at 6-under 134 and one shot ahead of first-round leader Tom Kite.

The 56-year-old Ten Broeck, who caddies for Tim Herron, finished tied for 71st at his only other Champions Tour event this year. He estimates he plays about 25 rounds a year.

“I guess that means I’m well rested,” he joked.

Ten Broeck got a chance to sleep in before starting the third round because he earned a spot in the final pairing.

“I knew I was playing pretty good in spite of having not really played much,” he said. “But I figured I should be able to make the cut, but I never figured that I’d be in the last group on Saturday.”

While many fans were likely stunned to see Ten Broeck atop the leaderboard, Kite insisted he wasn’t shocked.

Kite has known Ten Broeck since he was a standout golfer at Texas in the mid-1970s. The Chicagoan went on to play in 349 PGA Tour events, finishing a career-best second at the 1991 Chattanooga Classic in one of his 10 top-10 finishes.

“I played a bunch of golf with Lance when he was in Austin,” Kite recalled. “He’s had so much talent for so many years, and to a lot of people’s minds, didn’t take advantage of all the talent that he has.”
