MINNEAPOLIS, OCT. 17 -- In front of millions watching on television and 55,171 at the Hubert H. Humphrey Metrodome, the Minnesota Twins gave a demonstration of Domeball tonight to the St. Louis Cardinals.

The Twins have a power-laden lineup, and at the Metrodome, they had the league's best record at home. Tonight, Dan Gladden -- known more for his speed than power -- left his mark on Game 1, driving in five runs, including a fourth-inning grand slam, that propelled the Twins to a 10-1 romp over the Cardinals.

Gladden hit only eight homers during the regular season.

"We're going to enjoy it and have a beer and relax and come back tomorrow," said Gladden, who had an RBI double in the seventh to come within one RBI of the all-time mark for a Series game, six, by Bobby Richardson in 1960. "We've got to do our homework and study {Game 2 pitcher Danny} Cox."

The Twins were already leading, 4-1, when they loaded the bases in the bottom of the fourth with none out. Gladden hit a 1-1 pitch from reliever Bob Forsch into the left field seats for the first grand slam in Series play since Dave McNally's for the Baltimore Orioles in 1970.

"{Forsch} threw a curveball," Gladden said. "He had thrown one before that I squibbed down to first base, and then he threw another one that just hung over the plate."

"Dan got kind of embarrassed in Detroit when he struck out on three breaking balls with the bases loaded," Minnesota Manager Tom Kelly said in reference to Gladden's Game 4 strikeout in the American League playoffs. "Since then, he's gotten some big hits and key RBIs for us."

Against the Tigers in the American League Championship Series, Gladden had five RBIs, including a two-run single in the fourth inning of Game 2 that provided the eventual game-winning runs. In Game 5, he went three for six, with two doubles, a single and two RBI. He hit .350 from the leadoff spot in the AL playoffs.

"You never know who can be the hero, or get the team going on any given night," Twins shortstop Greg Gagne said. "Tonight, it was Danny and {Steve} Lombardozzi."

Gladden came to the Twins in a late spring training deal with the San Francisco Giants, with whom he set a club record for stolen bases by a rookie in 1984. Although he said he had no ill feelings toward the Giants' management, he also still is not entirely sure why he was dealt.

"Before I even went to camp, I knew I was going to be traded," he said. "They said, we're not going to renegotiate a contract with you. You can renegotiate with your new club."

He watched the Giants lose in seven games to the Cardinals, and said it wasn't easy to do. "It hurt when they had the camera in the Giants' dugout," he said. "I think it hurt me as much as it hurt them. I felt the loss with them."

But he's doing fine with Minnesota, where Gladden hit .249 during the regular season, with a club-leading 25 stolen bases. He is one of the team's top practical jokers, although that's hard to tell from his usually dour face.

"Ask around," he said. "You get to know me, you know I don't smile much."

"He is a little goofy," Lombardozzi said. "Let's just say he is a little different. I guess you would have to go around to each and every guy on the team and ask them. He has played a practical joke on practically all of us. Let's just stick with goofy."

On Gladden's grand slam, left fielder Vince Coleman looked like he might have a play, then ran back to the wall and watched the ball sail over the fence, as the sellout crowd got even louder than it had been.

"After Gladden hit the grand slam," Gagne said, "I was in the batter's box and my ears were ringing. I asked Tony {Pena, St. Louis' catcher} if his ears were ringing and he couldn't even hear me."

They were cheering for Gladden, whose nickname, Wrench, was slapped on him by Hrbek. "He just said I looked like someone who worked in a garage all day fixing engines," Gladden said. "It was Gladden Wrench and then just Wrench."

He was asked how it felt to be asked about hitting homers when he's known for speed. "That's not my style," he said, "but you guys need something to write about."
