Chris Speier's tie-breaking pinch sacrifice fly in the eighth inning gave Steve Trout and the Cubs a 2-1 victory over the Philadelphia Phillies yesterday in Chicago.

The win was the third straight and fifth in six games for the Cubs, their best start since 1975.

Philadelphia is 1-5.

Keith Moreland opened the eighth with a double to right off loser Kevin Gross and was replaced by pinch runner Davey Lopes. After Ron Cey struck out, Jody Davis was walked intentionally.

Rookie Shawon Dunston then looped a base-filling single to center before Speier, batting for Thad Bosley, hit his sacrifice fly off reliever Don Carman.

Lee Smith struck out the side in the ninth for his second save.

The Cubs scored an unearned run in the third inning to take a 1-0 lead. Bob Dernier singled and stole second. Gary Matthews grounded to short and Dernier was safe at third when he knocked the ball out of Mike Schmidt's glove for an error. Leon Durham then forced Matthews as Dernier scored.

Schmidt ended an 0-for-14 start with a single in the eighth that was wasted. "I knew if I stayed alive I would get a hit this year," he said.
