Then again, maybe Glavine should be ripping to go, already in possession of a 13-inning postseason scoreless streak. It's one that he is primed to continue, beginning with Cardinals leading man David Eckstein sometime after 8:19 p.m. ET Tuesday evening.
"All the talk is about me and Chris Carpenter," Glavine said, referring to St. Louis' ace, who is scheduled to pitch Game 6. "There's no guarantee that we're going to win the games. You expect based on track record that you're going to get a certain performance but you never know what's going to happen. And I think from our standpoint, we can't assume anything."
And three days or four days of rest, Glavine said, wouldn't make all that much difference.
"I think this time of year, your adrenaline is so high, you're so fired up about getting out there that I think that takes away from a lot of the feelings on the negative side," Glavine said.
"Most of it (on three days' rest) revolves around just being a little bit tired. You don't have that extra day that you're accustomed to so maybe you don't have as much zip on your pitches as you're accustomed to or maybe you're physically just not feeling the way you're accustomed to. But this time of year, I don't really think that's as much of a factor. I think the physical side of it is taken care of by the adrenaline."
The flip side of the equation is that Cardinals starter Jeff Weaver, Glavine's mound opponent from Game 1, will be able to come back on full rest for St. Louis as well.
Weaver took the loss on Oct. 12 at Shea Stadium in the Mets' 2-0 victory, allowing a two-run homer to Carlos Beltran and three other hits over a 5 2/3 inning effort.
"To me, (you) come to the ballpark and you're ready to play, you want to play," Mets manager Willie Randolph said. "I don't see where this necessarily makes a big difference. It's one game and sometimes guys go and do real well on three days."
Even though Weaver's struggles in New York – particularly as a member of the Yankees – have been well chronicled, home hasn't been where his heart is, either.
Weaver went just 2-7 with a 7.70 ERA in 14 home starts this season, although seven of those came when Weaver was a member of the Los Angeles Angels of Anaheim, faring 1-4 with a 9.09 ERA.
In his last three starts of the year at Busch Stadium, Weaver went 1-1 with a no-decision.
"I just think it was I had a couple starts at home when I first came over and I was still struggling a bit," Weaver said. "I had not found my niche and still was battling mechanics or mind thought or whatever else.
"But you know, I had a couple good starts here at the end at home, and you know, it's just one of those things where I think that for whatever reason, just matched up better on the road or whatever it may be. You know, baseball is kind of strange like that."
Glavine said the Mets are ready, having evened the series in Game 4 with a 12-run outburst against Cardinals rookie starter Anthony Reyes and St. Louis' (up to that point) stellar bullpen.
But, then again, they've been ready pretty much all of the year.
"It's not like we went through the year without any adversity whatsoever," Glavine said. "You don't play 162 games without facing some adversity during the course of the year.
"I think most of the time, we faced the adversity pretty well. Judging from the way the guys are right now in the clubhouse, everybody's pretty loose and ready to go."
