Larry Bowa's one-out suicide squeeze bunt scored Keith Moreland with the winning run in the 14th inning yesterday in Chicago to give the Cubs a 9-8 victory over the St. Louis Cardinals.

With one out, Moreland doubled off reliever Ken Dayley (3-1). Jody Davis was intentionally walked and Bob Dernier, batting for winning pitcher George Frazier (6-4), walked. On a 2-2 pitch, Bowa bunted to Dayley, who threw wildly to the plate as Moreland slid home safely.

The Cardinals tied the score at 8 with three runs in the ninth off reliever Lee Smith. Tommy Herr singled home one run and Jack Clark tripled home two more.

St. Louis took a 2-0 lead in the first, thanks to an unusual double steal. Vince Coleman singled and Willie McGee walked before attempting the double steal. Coleman overslid the base but Ron Cey missed the tag at third. Coleman proceeded to score on the play as no one was covering home plate on the ensuing rundown. McGee wound up at third on the play.

They were credited with two stolen bases each on the play, enabling Coleman to break Juan Samuel's year-old rookie stolen base record of 72. Coleman now has 74 stolen bases.

McGee scored on Clark's RBI single.
