George Foster's second home run, a two-run blast in the 14th inning, earned the Cincinnati Reds a 10-3 victory over Atlanta as the National League closed its regular season.

Foster finished with a league-leading 40 home runs and 120 RBI. His first homer, in the eighth inning, allowered him to surpass Pittsburgh's Dave Parker for the RBI title. Both had gone into the final day with 117.

Parker, who sat down after an 0-1 day at the plate in Pittsburgh's 5-3 victory over the East Division champion Philadelphia Phillies, won the league batting title with a .334 average.

The Cincinnati Reds closed the season at home with seven straight victories. Pete Rose failed in his bid to equal Ty Cobb's record of 200 hits or more in nine seasons.

Rose needed three hits yesterday, but got only one.

The Dodgers ended the regular season on a losing note, 4-3 to San Diego. Pinchhitter Oscar Gamble unloaded a bases-loaded single in the 11th inning. In that game, Gaylord Perry, who worked the first 10 innings for San Diego in an effort for his 22nd victory, reached the 3,000 career strikeout plateau.

At St. Louis, Tony Perez completed a 5-for-5 day with a two-run single in the ninth inning that enabled Montreal to beat the Cardinals, 5-1, and make Rose Grimsley the first 20-game winner in Expo history.

In other games Cesar Cedeno blasted his first home run since May 23 and three Houston pitchers combined on a five-hitter as the Astros shut out San Francisco, 3-0, and Butch Benton's first two major league hits helped the New York Mets defeat the Chicago Cubs, 5-3.
