Host St. Louis learned that ace shortstop Ozzie Smith will be out atleast 10 days with a contusion on his right thigh, saw starting pitcher Joaquin Andujar knocked out of the game by a line drive off his leg, but preserved and climbed back into first place in the East Division.
George Hendrick slugged his first home run since July 31, with two on base, as the Cardinals built a 6- 0 lead before reliever Jeff Lahti gave up a three-run homer to Dave King man, his 36th for the League lead over Atlanta's Dale Murphy.
Andujar (12-10) was struck above the right knee by Ron Hodges' Liner leading off the fifth and finished the inning before being replaced by Lahti. "X-rays are negative, that's all I know," Manager Whitey Herzog said later. "Whether he'll be able to pitch I don't know."
Lahti cruised into the ninth before Bob Bailor and Ellis Valentine singled and Kingman homered for the third straight game. With none out, Bruce Sutter took over and made his 31st save.
Hendrick's 17th homer came in the sixth inning off Ed Lynch (3-7), who until then trailed only 1-0 on an RBI single to Dane Iorg in the first.
Two errors by New York third baseman Hubie Brooks helped St. Louis to two runs in the eighth without a hit.
