Rick Sutcliffe of the Chicago Cubs brought his 16-game regular-season winning streak into Montreal for the Expos' home opener yesterday, but pinch-hitter Jim Wohlford's three-run homer in the sixth inning beat him, 5-3.

Sutcliffe hadn't lost in the regular season since last June 29, although he lost to the San Diego Padres in the final game of the NL playoffs Oct. 7.

Journeyman Wohlford had hit 19 homers in 13 major league seasons. From 1972 to 1983, he never had more than two homers in a season.

"I hope that gives them some respect for our bench," he said. "The reserves on this team worked hard this spring. You just have to gear yourself mentally to sitting on the bench and then be ready anytime you're called upon."

Ron Cey's second homer of the season gave the Cubs a 3-1 lead over Bryn Smith (2-0). But Vance Law singled to open the Expos sixth. He took third when shortstop Shawon Dunston threw wildly on Mike Fitzgerald's infield single. One out later, Tim Raines' RBI double finished Sutcliffe (2-1). Wohlford hit Ray Fontenot's 0-1 pitch into the left field seats.
