Andre Dawson's bases-loaded grounder with one out in the 17th inning gave the Montreal Expos a 1-0 victory over Philadelphia tonight as Phillies left-hander Steve Carlton became the National League's all-time strikeout leader.

Rodney Scott hit a one-out single and stole second. Reliever Jerry Reed (0-1) then walked Warren Cromartie and Terry Francona to load the bases. Dawson hit a hard shot to Mike Schmidt at third, and Scott narrowly beat the throw home.

Rookie Bryn Smith (1-0) got the win in relief in the longest game in the National League this season.

Carlton, 36, went 10 innings and struck out 12. He struck out Larry Parrish in the second inning and Dawson in the third with the bases loaded to raise his total to 3,118, surpassing Bob Gibson as the league's strikeout leader. He finished the night with 3,128.

In his 16th season, Carlton also moved into fourth place on the all-time strikeout list behind Walter Johnson's 3,508, Gaylord Perry's 3,326 and Nolan Ryan's 3,229. Cincinnati right-hander Tom Seaver has 3,067.

Carlton has struck out 10 or more 58 times in his career and has more strikeouts than any left-hander in history. He recorded his 3,000th strikeout earlier this season against Montreal's Tim Wallach.

The St. Louis Cardinals traded Carlton, now 11th on the all-time victory list with 261, to the Phillies in 1972 in exchange for pitcher Rick Wise.

Like Carlton, Montreal's Ray Burris pitched 10 innings, allowing three hits. It was the longest outing by an Expo pitcher this season.
