Steve Carlton of the Phillies struck out the Montreal Expos' first three batters last night in Philadelphia to become the first left-handed pitcher in the history of baseball to record 3,000 strikeouts.

Carlton (4-0) struck out nine in the game, running his total to 3,006, and drove in three runs with a single and a double as the Phillies won, 6-2.

Carlton, the 1980 Cy Young Award winner in the National League, is sixth on the all-time strikeout list. He trials Walter Johnson (3,508), Gaylord Perry (3,293), Nolan Ryan (3,128), Bob Gibson (3,117) and Tom Seaver (3,010). Perry, Ryan and Seaver still are pitching.

The only other left-hander to approach the 3,000 mark was Mickey Lolich, who pitched most of his career with the Detroit Tigers and finished with 2,679.

The Phillies took a 1-0 lead in the second when Gary Matthews doubled, took third on Keith Moreland's ground out and scored on a sacrifice fly by Garry Maddox.

Maddox singled, moved up on Larry Bowa's sacrifice and scored on Carlton's single to make it 2-0 in the fifth. Carlton doubled home a run in the seventh and set up a three-run pinch double by Del Unser as the Phillies chased Steve Steve Rogers (2-1) with four runs.
