This is where it got a jump start in baseball:
"The Cubs started Greg Maddux -- coming off a 19-12, 2.95 showing in just his second full season -- and Clark simply owned him. He doubled to left-center for a 1-0 Giants lead in the first. He got a low sinker in the third and golfed a solo homer to right for 4-2. Then he unleashed the blast that clinched the game and, in an odd way, altered the course of Maddux's career.
It was the top of the fourth, two outs and the bases loaded, San Francisco clinging to a 4-3 lead, and Cubs manager Don Zimmer came out to visit Maddux. Left- hander Paul Assenmacher was looming in the bullpen, but Kevin Mitchell was on deck. The decision was to leave Maddux in the game and to try to "jam" Clark with an inside fastball.
How did Clark know that? "I read his lips," Clark said the other day. "I was standin' there adjusting my batting glove, and I had a clear view of Maddux' face. I could see him say 'fastball in' to Zimmer. Well, shoot (laughter) . . . I guess they'd been poundin' me away, but if they want to come inside, go right ahead."
At the worst possible time, Maddux's fabled control deserted him. He threw the first pitch right down the middle, and Clark hit a grand slam into the street beyond the right-field bleachers at Wrigley. He wound up going 4-for-4 in the Giants' runaway victory, and when Maddux learned he had tipped off the pitch, he made a huge adjustment.
"That's why whenever he talks to the catcher now, he puts his glove up over his face," said Clark. "Unfortunately for him, he didn't do it then."
