Ben Crenshaw shot a five-under-par 67 Saturday to take a two-stroke lead over Ronnie Black with a 54-hole total of 15-under-par 201 in the $500,000 USF&G tournament at New Orleans.
Black, meanwhile, shot a three-under 69, despite a bogey on the 18th hole. He's at 13 under par.
Tom Watson, Curtis Strange and Jay Haas each shot a 66, and Keith Clearwater had a 65 to create a four-way tie for third at 204. Second-round leader Dick Mast came in at 73 to fall four shots off the pace at 205 along with Bob Gilder, who was a shot off the lead going into Saturday's round.
Gilder was 15-under after 13 holes and tied with Crenshaw, but he shot double-bogeys on the 14th and 15th holes to post an even-par 72.
Jan Stephenson shot a one-under-par 71 and increased her lead to three strokes after three rounds of the $200,000 Tucson Open with a 54-hole total of 208, eight under par.
