All-Stars Andre Dawson, Gary Carter and Steve Rogers came through and Scott Sanderson won his first game since May 27 as the Montreal Expos, in jeopardy of losing first place in the National League East on July 4, righted themselves and stopped the Cubs, 6-3 and 4-2, yesterday in Chicago.

Dawson hit his 16th and 17th home runs and a double in the first game. Carter homered in each game as the Expos, starting the day one game ahead of Philadelphia and St. Louis and two in front of Chicago, gained ground on each.

Rogers (12-3) ended the Expos' losing streak at five games and the Cubs' winning streak at six. Sanderson (5-6) stopped Chicago on three hits until he left in the seventh after running out a ground ball. He ruptured a tendon in his thumb as he stumbled over first base and is expected to be placed on the disabled list.

Carter was hit by pitches three times during the five games with the Cubs this weekend, including once by Ferguson Jenkins yesterday in the second game. But Carter noted, "Instead of going out there and starting a fight, you do it with your bat."
