SAN FRANCISCO, OCT. 10 -- The Giants' Hac Man and Yac Man backed up their bravado with deeds tonight in Candlestick Park, tying the National League Championship Series at two games each with a 4-2 victory over the St. Louis Cardinals.

"Somebody will pay," said an angry Jeffrey Leonard before this game. Drill me with a fastball, will you, just because I'm killing you with home runs, then Cadillac trotting 'round the bases to my heart's delight. So, The Hac Man went out and hit a homer for the fourth consecutive game -- a playoff record. This time, his two-run, wind-aided fly over the left field fence in the sixth inning gave the Giants a 3-2 lead and made a loser of Danny Cox.

"I'll just go out and pitch a shutout," Mike Krukow told his teammates Friday night, after an awful loss. "Then we can't lose." The charming, motor-mouthed Krukow, who might be able to outtalk Dizzy Dean, was almost as good as his word, pitching a scruffy, gutty nine-hitter in which he was aided no end by four double plays and Mike Aldrete's diving, run-saving outfield catch.

"For those of you who don't know what 'Humm baby' means, you saw it tonight," said Giants Manager Roger Craig, who also got solo home runs from Robby Thompson in the fourth and Bob Brenly in the eighth. "People thought last night would be a devastating blow to us. But this club just keeps coming back all year.

"Krukow won 20 {games} for me {in 1986}. All 20 of 'em couldn't count for this one. He could have had a shutout if we'd played right behind him in the {two-run} second inning."

"Winning 20 was a nice personal accolade," said Krukow, who was only 5-6 this season because of injuries. "But this was so totally different. We've got a chance to make a little history and be remembered.

"That was a stat on a baseball card. This is a chance for a little piece of immortality . . . There will be pressure on us until we can stomp the last breath out of our opponents."

Yes, the Giants and Cardinals really love each other that much.

For the Cardinals, who had Terry Pendleton back at third base, sore ankle and all, and got a complete game from the stiff-necked Cox, this was an evening to grumble about the miserable Candlestick Park winds. No park has such short power alleys -- 365 feet -- or such ridiculously influential jet streams.

"The wind just kept taking the ball over the left field fence," said Cardinals Manager Whitey Herzog. "Brenly's was out, but the other two . . .

"We never hit one up in the air that way and the wind was blowing for us, too."

Leonard, the vociferous No. 00, who has not stopped bragging, threatening, belittling and baiting since this series began, was in rare form after being hit by one of Bob Forsch's pitches after his Game 3 homer.

"Some time, at some point, we will take care of that," Leonard said after that game. "You're thinking along the lines of kicking somebody's butt. It could come in a big hit. Like I said, somebody will pay."

Leonard needed help, yet did, indeed, make good his revenge, rounding the bases with his "flap down" -- the most modest of his many homer struts. "I really didn't think that ball was going out," said Craig. "I don't think Jeffrey did, either. But when you're hot, you're hot."

"Hit it good," Leonard said. "Had a little doubt. Up in the wind. See ya later."

His glory was the work of a moment. Krukow carried the weight all night. He was rocked early and was on the verge of an early shower. In the middle innings he cruised. Then, he got flashy double plays to end each of the last three innings -- fitting, because the Giants turned a league-high 186 double plays.

"Brenly and I decided to stay on their hands with hard stuff, then throw some ducky {ie., soft} stuff out front," said Krukow. "But they'd still drop in a dead bird or a line drive . . . They can generate offense with singles. When they get started, they're a carrousel."

The merry-go-round began in the second when Curt Ford, Tony Pena, Cox and Vince Coleman got consecutive one-out singles to score two runs and leave men at the corners. One more hit and Krukow might have been gone. "I don't know. Yeah, probably. They had a red alert down in the bullpen," admitted Krukow. "Sparks were coming out of there. Then, Ozzie {Smith} hit a seed."

That seed, however, found the glove of a diving Thompson. Coleman wandered far off first, an awful mistake, and was doubled to end the inning. "I had a chance to regroup," said Krukow. "That was the big play."

Thompson, who'd been hitless in the series, made one error and had flu, might also have regrouped. His homer brought the big crowd to life and got the stadium rock 'n' roll turned up high.

"One of our keys is that we've been a very resilient team," Krukow said. "Not so much cheerleading. Just open discussion. We knew our backs were against the wall."

The Cardinals, finally returning to good health, had little to enjoy. When Smith tried to score Coleman with a liner to right in the fifth, Aldrete made a face-full-of-mud catch worthy of the Wizard of Oz himself.

True, Pena got to smack Leonard in the face with a tag at home that knocked No. 00 head-over-teakettle in the seventh when he tried to score from first base on Will Clark's double. That was the extent of the visitors' pleasure as this playoff begins to bear the earmarks of a seven-game war and a good old-fashioned National League feud.

"We like to do it on the field," Tom Herr of the Cardinals said. "We don't show up teams and we don't like to be shown up.

"We don't showboat on the bases like they have," added teammate Jim Lindeman.

"We're not the type that woofs," summarized Ford.

Leonard, the type that definitely woofs, now joins Steve Garvey (then with the Los Angeles Dodgers) and Bob Robertson of the Pittsburgh Pirates as players to hit four homers in one playoff series.

On Sunday here at 4:35 p.m. EST, the Giants will send their best and most silent pitcher, Rick Reuschel, against Greg Mathews, the Cardinals' chatterbox southpaw who beat Reuschel in Game 1.

In every game of this series, the team that has entered the game an underdog has won. Now that the Cardinals are half healthy and the Giants have pulled even, nobody seems to have much of an edge.

So, with that little bit of immortality at stake, the pressure mounts.
