ST. LOUIS, OCT. 14 -- St. Louis Manager Whitey Herzog tonight began making plans for his team to deal with the peculiarities of the Metrodome.

Even though their pennant-clinching celebration was expected to last well into the early hours of Thursday, Herzog and the Cardinals were to fly to Minneapolis Thursday and hold a 7 p.m. workout in the dome.

When the Cardinals signed former California Angel Doug DeCinces at the end of the season, Herzog and DeCinces talked several times about the stadium. DeCinces warned Herzog that he should get his team into it as early as possible.

"He said it took at least three or four days to get used to the lighting," Herzog said. "That's tough since you usually play only three games there."

Herzog has another reason for going to Minneapolis early. He wants to hold a simulated game for injured first baseman Jack Clark, although he's under no illusions Clark's right ankle will allow him to play.

"I don't think he'll be ready," Herzog said, "but {with the designated hitter rule in}, I want to see if he can put any weight at all on the foot."

Tudor in 2, Cox in 3

Herzog declined to name a starting pitcher for Game 1, although he did announce that John Tudor would pitch Game 2 and that Danny Cox would start Game 3. He didn't want to risk pitching Tudor again on three days' rest, and appeared to be leaning toward either left-hander Joe Magrane or right-hander Bob Forsch for the opener.

Greg Mathews pitched well in the playoffs (3.48 ERA), but apparently is still bothered by a pulled thigh muscle. Magrane pitched only four innings in the championship series and allowed four runs. Forsch pitched three innings and had a 12.00 ERA.

Forsch could be the choice because the Twins had the American League's best record against left-handed pitching.

"I've got to talk to my coaches and scouts and see what they say about the Twins," Herzog said.

Pendleton's Injury

What would a Cardinals game be without another injury? They got one in the second inning when Terry Pendleton pulled a muscle in his left side while rounding second. He left the game in the third inning, but Herzog said he "expects" Pendleton to play Saturday . . .

Herzog also was planning a roster move, to go from eight pitchers to nine. It appears he'll drop Tom Pagnozzi and add another pitcher, probably right-hander Lee Tunnell.

Craig's Moves

Giants Manager Roger Craig juggled his lineup tonight, starting Mike Aldrete instead of Candy Maldonado in right field, Chris Speier at second instead of Robby Thompson and Bob Brenly instead of Bob Melvin at catcher.

The most surprising move was benching Thompson, who was hitting just .105 but had homered off Cox in Game 4. The other surprise was in benching Madonado instead of Chili Davis to make room for Aldrete.

Craig denied the move had anything to do with Maldonado's misplay that decided Game 6.

"I'm just playing the hot guys," Craig said. "Defensively, there's not a lot of difference between Robby and Chris, but Robby has really been struggling. I think Chili (.188) has been swinging the bat well, although it may not look it.

"I'm playing guys I feel can help the most. I can't worry about personal achievement things now. I've got to put a lineup out there I think can win. Who knows? Candy might come off the bench and get a big hit." He didn't. Front Office Follies

General managers were once the guys with job security, but with today's resignation of Houston's Dick Wagner, 13 of the 26 major league teams have changed general managers in the last two years. There may be more chances because General Manager Woody Woodward is believed to be part of one of the changes Yankees owner George Steinbrenner is considering. Lee Thomas, the director of player development for the Cardinals, is considered a leading candidate to replace Wagner.
