Gene Michael, who earlier yesterday said he didn't want to manage the Chicago Cubs next year, will likely be dismissed by the team today, sources said.

Dallas Green, Cubs president and general manager, was not told of Michael's decision to go public with a desire not to return.

Sources told United Press International Green was upset about Michael's announcement and that an interim manager would be likely be appointed to finish the season.

John Vukovich, bypassed when Michael was hired in the summer of 1986 to replace Jim Frey, is the likely candidate to finish the season. Vukovich is the club's third base coach.

Michael's contract expires at the end of the season. He said in a radio interview after the Cubs' 3-2 loss to Pittsburgh yesterday in Chicago he made up his mind last week not to return.

"I have now decided I do not want to come back," Michael said. "I think we have a great ball club and a great set of coaches. And, while we are short in some areas, the players have done an outstanding job."

In the game, Bobby Bonilla recovered from two earlier strikeouts by hitting a two-run double off the left field wall in the eighth inning to score Barry Bonds and Jose Lind. It was the Pirates' 10th victory over the Cubs in 13 games this season.

Jeff Robinson earned his 11th save, his first with Pittsburgh. In the eighth, he struck out Leon Durham, Andre Dawson and Rafael Palmeiro on nine straight pitches, all swinging strikes. He became the 11th NL pitcher to accomplish the feat, the first since the Cubs' Bruce Sutter on Sept. 8, 1977.

Expos 9, Cardinals 2:

Andres Galarraga had three hits, including a homer and three RBI, as Montreal won at home.

Galarraga is 24 for 47 (.510) against St. Louis this season with three home runs and 10 RBI.

"I get pumped up against this team because they're a team we have to beat," Galarraga said. "Every game against them is very important because we're chasing them."

A crowd of 50,342, the largest in Olympic Stadium since opening day, saw Montreal move within four games of the East-leading Cardinals.

Phillies 5, Mets 3:

Kal Daniels homered and scored twice for the Reds.

Padres 11, Braves 4:
