Olin Browne takes over in Toledo from Mark O'Meara

Unflappable Olin Browne fought off the heat to shoot a 65 and forge a two-shot lead over Mark O'Meara going into last night's final round of the US Senior Open at Toledo, Ohio.

Browne, never a winner in his three years of competition since turning 50, set the tournament record for lowest score through 54 holes. After a record-tying 64 was followed by a 69, he stood at 15-under-par 198.

O'Meara, winner of the 1998 Masters and Open, had a 66 in a head-to-head duel.
