SAN FRANCISCO (AP) _ Pinch-hitter Rondell White hit a sacrifice fly in the ninth inning to lead the Montreal Expos to a 4-3 victory over the San Francisco Giants on Sunday.

The Giants lost for the seventh time in their first eight games at new Pacific Bell Park.

Andy Tracy and Peter Bergeron each singled with one out in the ninth off John Johnstone (2-2). White, who hadn't started the last three games because of a bone bruise in his left knee, hit a drive to deep left field that scored Tracy without a throw.

Scott Strickland (2-0) pitched a perfect eighth for the win, and Ugueth Urbina got three outs for his seventh save.

Barry Bonds hit his 10th homer of the season for the Giants, a solo shot that put San Francisco up 3-2 in the fifth.

Michael Barrett's first home run of the season tied the game at 3 in the seventh. The Expos nearly went ahead later that inning when Vladimir Guerrero tripled with one out for his first hit in the series.

After Lee Stevens was walked intentionally, Aaron Fultz relieved Giants starter Joe Nathan and got pinch-hitter Orlando Cabrera to pop out. John Johnstone then got Chris Widger to ground out to end the threat.

Expos starter Carl Pavano allowed three runs _ two earned _ and five hits and five walks. He struck out three.

Nathan allowed three runs _ two earned _ and four hits in 7 1-3 innings.

Rich Aurilia scored on a throwing error and Marvin Benard hit a sacrifice fly to give the Giants a 2-1 lead in the second. Nathan's sacrifice bunt turned into a single and Pavano threw the ball away at first, allowing Aurilia to score from second.

Jose Vidro's infield grounder scored Peter Bergeron to put Montreal on top 1-0 in the first.

Widger had an RBI double in the fourth to tie the game at 2 for the Expos.
