LAKE ORION, Mich. — Lance Ten Broeck chooses to carry a bag rather than swing a club for a living to make more money.

If Ten Broeck can keep his lead at the U.S. Senior Open for two more days, though, he will more than double his highest annual income on a golf course.

The full-time caddie for Tim Herron and part-time player shot a 68 Friday, putting him at 6-under 134 and one-shot ahead of first-round leader Tom Kite.

Ten Broeck has a chance to make about $500,000 on Sunday after earning less than half that total in his best year as a caddie and when he made a career-best $146,568 in 1989 as a PGA Tour player.

It won’t be easy for Ten Broeck to cash in at the Champion Tour’s fourth of five majors because he’s only a shot ahead of Kite, who has been sensational on his front nines at Indianwood.

Ten Broeck is also two strokes in front of a pack of six that includes Tom Lehman, Corey Pavin and Bernhard Langer.
