This was Scott Podsednik, a guy who didn't hit one over the fence the entire regular season. And this was Astros closer Brad Lidge on the mound, one of the best closers in the game.
"Wow. I mean, wow, what a game," said White Sox catcher A.J. Pierzynski. "For Podsednik to hit a home run off of Lidge, it's something that just doesn't happen."
But it did happen, and it fit right in with the rest of what turned into a stunner of a game that fits right in with some of the greatest nights in World Series history.
History writes itself in October, and Game 2 was a brand new chapter with its very own hero and its very own storyline. It wasn't the greatest game ever played, but it had some of the greatest twists and turns of any World Series game, that much is clear.
Seven outs from the series being tied, 1-1, Paul Konerko launched a grand slam that rocked the Astros and sent the U.S. Cellular crowd rocking and rolling, giving the White Sox a 6-4 edge.
Seven outs sound familiar? That's how many the Angels had left in Game 6 of the 2002 World Series before Scott Spiezio's three-run shot led the way to an Angels rally, which led to the World Series title a day later.
This one has a ways to go before it leads to a title, but what a feeling. Nothing could top it for Konerko -- well, almost.
"It's the second-best feeling I've had all week," the White Sox first baseman cracked. "The baby born Tuesday night, that's first for the week; [the grand slam] is second."
It turned out to be part of a week's worth of stunning moments in this one.
Before the grand slam, there was the hit batter that was really a foul ball off the bat of Jermaine Dye. Home-plate umpire Jeff Nelson awarded Dye first base, and Dye gladly took it without argument, and wound up crossing home plate just before Konerko on the grand slam.
But then the Astros wrote their own plot twist, putting two men in scoring position and letting Jose Vizcaino reprise a World Series moment he had with the Yankees -- delivering in the clutch to tie the game.
And the story was made complete with the surprise ending supplied by Podsednik.
Put it where you like in the annals of World Series greatness. It might not have been Carter, Gibson or Puckett, but it was pretty amazing and, unless you're an Astros fan, pretty darn cool.
Those other guys were sluggers, even though Gibson was hobbled enough to inspire a cereal commercial almost two decades later.
Podsednik was more likely up there to get an infield single, and the White Sox would have been ecstatic to get it just to get a rally going.
Instead, he delivered a big fly that has Chicago soaring to Houston with a 2-0 World Series edge, leaving them just two wins from their first World Championship since 1917.
Add it all up, and it's a new and amazing story in World Series lore. Certainly, Sox fans -- and probably Astros fans, as well as just plain old baseball fans -- will be telling their children and grandchildren all about it.
Indeed, the thrill of the first World Series game in almost a half-century for the White Sox the day before was trumped by the chills of a World Series game unlike any other before it.
"I've never been in a game like that one tonight," White Sox center fielder Aaron Rowand said. "Not one. Ever. Everyone thought last night was exciting, but I hope they tuned in tonight.
"You can't explain it. There's something special going on tonight. It's unbelievable and I can't think of anything to describe it."
