Jose Cardenal drove in four runs with a homer and a single today to lead the Chicago Cubs to a 9-4 victory after the San Diego Padres won the opener, 8-6, on two-run homers by Dave Kingman and Gene Tenace.

The split left the Cubs one game behind the first place Philadelphia Phillies in the National League East.

The second game was marred by a free-for-all with both teams emptying onto the field in the second inning after Kingman slammed into Mick Kelleher trying to break up a double play. The two got up and started fighting. Both were ejected.

Cardenal hit his third homer of the season after a walk and a hit batter in the first inning. He singled in a run in the second after Steve Swisher had hit his fourth homer.

Ivan DeJesus opened the first inning of the nightcap by drawing a walk and loser Bob Shirley hit Larry Bittner with a pitch before Cardenal homered. Winner Steve Renko hit Kingman with a pitch in the second and umpire John McSherry warned both managers. Moments later George Hendrick forced Kingman at second and the fight broke out.

Pat Scanlon singled in an unearned run in the Padre fifth and the Padres added three more in the eighth on a solo homer by Gene Richards and a two-run homer by Jerry Turner.

Bobby Murcer put the Cubs ahead 3-0 in the first game with a three-run homer in the first inning. Tenace's 11th homer helped the Padres forge a 3-3 tie in the first game and Kingman's 18th homer in the fifth put San Diego ahead to stay at 5-4.
