PHILADELPHIA (AP)—Rick Sutcliffe and the Chicago Cubs kept their winning streaks alive Sunday, but it wasn’t pretty.

Sutcliffe improved his record to 3-0 and drove in two runs with a bases-loaded single as the Cubs won their seventh straight game, 5-3, over the Philadelphia Phillies.

Sutcliffe allowed six hits, struck out four and walked five before leaving with one out in the ninth.

“I don’t know how I got by today,” he said. “There was a lot of luck involved. Nothing I did was pretty. It’s hard to believe we won the game.”

After Sutcliffe walked two batters in the ninth, Mitch Williams came in and gave up RBI singles to Tommy Herr and Chris James before retiring Mike Schmidt on a fly to right to gain his sixth save.

While Sutcliffe wasn’t that sharp on the mound, he was effective at the plate. His bases-loaded single in the fifth off Floyd Youmans, 0-2, gave the Cubs a 5-1 lead.

“Sutcliffe’s hit really hurt us,” Phillies manager Nick Leyva said. “If we get him out, it’s a different ballgame.”

The Cubs, whose winning streak is their longest since 1985, took a 1-0 lead in the first when Mark Grace’s two-out single scored Mitch Webster, who had reached on a bunt single and moved up on Ryne Sandberg’s walk.

The Phillies tied it in the bottom of the inning on a double by Von Hayes, the league’s leading hitter, and an RBI single by Herr.

Hayes’ first-inning double was his only hit in four at bats Sunday—a highlight for the Cubs pitchers considering Hayes’ .600-plus batting average against Chicago this season.

The Cubs made it 2-1 in the fourth when Shawon Dunston walked, stole second and went to third when catcher Darren Daulton threw the ball away. Dunston scored on Jerome Walton’s sacrifice fly.

Sandberg led off the fifth with a single off Youmans, and Grace singled one out later. Vance Law doubled in Sandberg and, after an intentional walk to Andre Dawson and Joe Girardi’s foul pop-up, Sutcliffe singled to left for two more runs.
