Sunday Warm-Up - US GP

Briton David Coulthard headed the times in the warm-up for Sunday's United States Grand Prix, ahead of McLaren teammate and defending world champion Mika Hakkinen of Finland.

Coulthard, in determined mood as he bids to keep alive his faint hopes for the drivers' world championship, clocked a best time of 1:23.144 to outpace series leader Hakkinen by half a second.

German Michael Schumacher, who will start Sunday's race from pole position with Coulthard alongside him, was third fastest in his Ferrari, with Canadian Jacques Villeneuve fourth for the BAR team.

The session was run in cool, damp and overcast conditions on a wet track and saw several drivers sliding off the circuit, mostly laid out across the infield of the famous 2.5-mile Indianapolis oval.
