The Montreal Expos didn't make things easy on themselves. In Colorado, they rarely do.

James Mouton scored on an error by Colorado first baseman Todd Helton with two outs in the 10th inning yesterday afternoon as the Expos held off the Rockies, 14-13, in the first game of a doubleheader.

The Expos, who had lost four straight in Denver, got homers from Shane Andrews, Geoff Blum and Rondell White and survived despite wasting leads of 6-1, 12-6 and 13-11.

"I've been here too many times. There's no big leads," said Montreal Manager Felipe Alou. "The only big lead is after you win the game and you make sure there's no appeal of anything and you're in the clubhouse."

After Neifi Perez's RBI double off Ugueth Urbina (6-4) tied the game in the ninth, the Expos pushed across an unearned run against Jerry Dipoto (3-4) in the 10th.

Chris Widger walked to open the inning and pinch-runner Mouton stole second. He moved to third on a ground out and scored when Wilton Guerrero's grounder bounced off Helton's leg.

Anthony Telford earned his second save with a perfect 10th that put an end to another high-scoring game in Denver.

Teams have reached double figures in runs 33 times at Coors Field this season, including nine games where both teams did it.

After Colorado -- which has lost 16 of 20 -- tied the game at 6 in the fifth, the Expos went ahead 12-6 in the sixth on Jose Vidro's two-run single, Andrews's three-run homer and Blum's solo shot off Mike DeJean.

Blum's homer was his first in the majors. Andrews finished with a season-high four RBI, and Rondell White went 3 for 5 with three runs.

Montreal's Vladimir Guerrero extended his hitting streak to 17 games and played in his 259th straight game, tying Rusty Staub's club mark.
