Ron Cey hit a three-run homer in the fifth inning and Leon Durham did the same in the sixth to lead the Cubs to an 8-4 victory yesterday over the Cincinnati Reds in Chicago.

Cey's homer, his third in the last three games, highlighted a four-run fifth inning off Charlie Puleo (0-1). Durham's three-run homer came in a four-run sixth off reliever Rich Gale.

"The park hurt me at the beginning," said Cey, whose homer was his fourth of the season. "The coldness and the northwest wind hurt. When the wind is a crosswind like today, the ball is going to carry more."

Paul Moskau (2-2) pitched the first 5 2/3 innings to gain the win, the Cubs' first over the Reds in six games this season. Mike Proly went 2 1/3 innings before being replaced by Lee Smith, who allowed an RBI ground out by Wayne Krenchicki before finishing off the Reds.

Cincinnati took a 1-0 lead in the first when Eddie Milner singled, took second on Moskau's wild pickoff attempt and scored on Dave Concepcion's single.

The Reds added a run in the fourth. Ron Oester singled and scored when second baseman Ryne Sandberg and right fielder Keith Moreland collided on Paul Householder's fly ball that fell for a triple.

Sandberg was hospitalized with a mild concussion.

In the fifth, Tom Veryzer singled, took second on Bill Buckner's single and scored one out later on Moreland's RBI single. Cey followed by hitting the first pitch into the left-field bleachers for his fourth homer of the season.

Johnny Bench's 382nd career homer made it 4-3 in the sixth, but the Cubs broke the game open in the bottom of the sixth. Gary Woods lined a one-out double and scored on Junior Kennedy's single. After Buckner walked, Durham hit a 3-1 pitch into the left-field bleachers for his sixth homer of the season.

Cubs shortstop Larry Bowa and Manager Lee Elia were ejected in the first inning for arguing a third strike to Bowa.
