• Lance Ten Broeck, making only the fifth start of his Champions Tour career, forged a two-under-par 68 at Indianwood Golf & Country Club in the afternoon and finds himself one stroke ahead of 62-year-old Tom Kite, the first-round leader, after two rounds of the 33rd U.S. Senior Open Championship. Ten Broeck started on the back nine and rebounded from a bogey at No. 14 with an eagle on the following hole, sinking a 10-foot putt after a 240-yard second shot with a 3-wood. The journeyman from Chicago, who in recent years has been a caddie for several PGA TOUR players, played his second nine in one-under to post the 6-under cumulative total. Starting at the 10th tee, Kite reached 9-under for the tournament after a birdie at No. 18, but he dropped four strokes on his second nine, including a bogey on the last hole of the day to drop out of the lead.
