People around Major League Baseball are still recovering from the most unbelievable final Friday of any regular season. Did you see that? Of course you did. You saw everything. You were locked in like it was a Halo 3 all-nighter. Your head was spinning like Brandon Webb's breaking ball from trying to watch up to a dozen games at once.

The Red Sox players were watching the Yankees, and who will ever forget how all those fans stayed at Fenway Park to watch Melvin Mora's game-winning bunt? The Cubs players were in Cincinnati, watching the Brewers get eliminated on TV and then popping the bubbly. The Diamondbacks figured out a way to stop the mighty Rockies, and that meant an incredible three champagne celebrations in one night.

"Happy! Exhilarated!" Red Sox closer Jonathan Papelbon said of his feelings in the clubhouse party, and that applied to a lot of us baseball fans on this weekend as well. It is hard to even imagine now how it must have been with two eight-team leagues where the two top teams just matched up in a World Series.

Here in the Wild Card era, this was excitement practically everywhere, with practically everyone watching everything. Maybe you were watching it on MLB.TV, clicking from one game to the next, while you had another game on the TV. Maybe you were watching your cable and ESPN highlights, with the radio on. Maybe you were listening to one game on MLB.com Gameday Audio, trying to somehow cover every base when so many simultaneous games had playoff implications. Maybe you were at a sports bar, watching every monitor you could possibly see.

Well, take a deep cleansing breath, meditate a little, and bring the energy back up because it's not like everything is suddenly all cleared up in Scenario City. Saturday brings another full slate of games, spread throughout day and night, and six of those games are still important to the Division Series picture. Ready?

If the Phillies win and the Rockies and Mets lose on this day, then all of the 2007 Division Series matchups are set. It would be Arizona vs. Chicago and Philadelphia vs. San Diego in the National League, and Boston vs. Los Angeles and Cleveland vs. New York in the American League.

Of course, there is a very good chance it won't be nearly that simple. There are plenty of tiebreaker scenarios if that doesn't happen. Familiarize yourself with them, and settle in for a long Saturday that should gradually sort things out even more. Maybe. Some of this may be up in the air on Sunday, and there could be at least one playoff tiebreaker necessary after that before Wednesday's first scheduled Division Series games on TBS.

Here is what to watch:

Saturday
The Marlins (Chris Seddon, 0-1) are at the Mets (John Maine, 14-10) at 1:10 p.m. ET. The Padres (Chris Young, 9-8) are at the Brewers (Dave Bush, 12-10) and the Nationals (Matt Chico, 6-9) are at the Phillies (Adam Eaton, 10-9) at 3:55. The Twins (Carlos Silva, 13-14) are at the Red Sox (Tim Wakefield, 16-12) at 7:05. The Indians (Jake Westbrook, 6-9) are at the Royals (Gil Meche, 9-13) at 7:10. The D-backs (Edgar Gonzalez, 8-5) are at the Rockies (Mark Redman, 1-4) at 8:05.

No team in Major League history has missed the postseason after leading its division by at least seven games on Sept. 12 or later. Will the Mets be the first? The Phillies now have a one-game lead in the NL East, and the Mets are two back in the Wild Card standings. Saturday is do-or-die. If the Phillies win and Mets lose, the race is over. Maine hasn't won in four starts over the past month, but he has held the Marlins to a collective .197 batting average this season. There are a couple of X-factors, and that is this apparent love affair the Marlins have with the spoiler role right now and also the presence of a rookie (Seddon) who on Sept. 23 held the Mets to two runs and three hits over five innings.

The Phillies are looking more and more like the prototypical Major League killer-instinct club that catches fire at the end of a regular season and wins world championships without caring what anyone thinks. Ryan Howard set the all-time single-season strikeout record, and do you think he cares in the least? He just homered yet again, Jimmy Rollins just made another big push for his MVP candidacy, and the team known to so many as a "tease" at this time of year is in control. Now it's anyone's guess what they get from Eaton, who has been erratic most of the year. It wasn't pretty, but at least his last start on Sept. 21 was a 'W' -- his first since July 20.

Every time he starts, the Padres expect that Young will hit double figures in his victory total. He got to nine right after the All-Star Game, an event that fans decided he should attend because of his wondrous first half. This is one of the great mysteries of the 2007 season. San Diego needs him to put No. 10 up immediately. How will Milwaukee react? It was a beautiful run in 2007 for the Brewers, but it's over. Can they do the spoiler thing? The Padres have won four in a row. They are one game behind Arizona in the NL West standings, and lead the Rockies and Mets in the Wild Card chase by two.

It's survival day for Colorado. Their division title prospects ended when their amazing 11-game winning streak was ended at home Friday by Webb and the D-backs. But they still have Wild Card hope. Redman is a journeyman with his eighth different club, but he brings some valuable postseason experience, having been part of that Marlins rotation during Florida's 2003 title run. Arizona, already assured of at least something, can clinch the NL West title with a victory in this game.

In the AL, it's all about the final records this weekend. We already know that the Yankees will open at Cleveland -- a team they have beaten in every meeting this season -- and the Angels will open at Boston. The Red Sox, having just ended New York's streak of nine consecutive division titles, now have the same 95-65 record as Cleveland. Boston would win the tiebreaker due to better season head-to-head record with the Indians, should they finish the weekend tied. It's important because the team with the best record could have home-field advantage through the World Series, and also because that team has the right this year for the first time to choose whether to play the maximum seven- or eight-day Division Series.

Sunday
The only two remaining contenders that could be eliminated by the time Sunday's games begin are the Mets and Rockies. If the Padres win Saturday, then the Mets have no chance for the Wild Card. It would not matter whether the Mets win or lose. As for the Rockies, they'd have to win Saturday and Sunday.

So there is a possibility that the final day of the regular season will dawn with the postseason field already set. And there is the possibility that there will still be some havoc, possibly even leading to at least one tiebreaker afterwards.

Will Tom Glavine pitch again in 2007? He is scheduled to start on Sunday, and he would be going for his 14th victory while opposing Dontrelle Willis (10-15). Jamie Moyer (13-12) hasn't pitched in the postseason since 2001 with Seattle, but he is poised to make his last regular season start on this day and possibly as a clincher. He would be facing Jason Bergmann (6-5) of the Nationals.

The Padres are scheduled to throw Brett Tomko (4-11) against Milwaukee's Jeff Suppan (11-12), while Doug Davis (13-12) starts opposite Ubaldo Jiminez (4-4) for Colorado. Although Suppan helped pitch the Cardinals to the last world championship, it should be noted that he was the only losing pitcher in that 2006 NLDS against San Diego, lasting just 4 1/3 innings against the Padres.

Two more days, maybe a little more. The picture is finally starting to come into focus, but only after a Friday night that will be remembered long after this postseason is through.

Who could forget the words of Bob Uecker, Hall of Fame broadcaster for Milwaukee radio WTMJ, speaking to the MLB.com Gameday Audio listener when everything was starting to move really fast:

"We're in the top of the eighth, San Diego trying to make it 2-0 in the series, Arizona leading Colorado, on our Kohl Scoreboard. Swing and a miss, he struck out Kouzmanoff. Padres gotta keep winning. Colorado has to win. They're tied for the Wild Card spot. And Arizona's not quittin'. They're playing in Colorado, and that game is now in the seventh. One man out. Adrian Gonzalez, and he took one high and outside ball one."

That's how it was. Everyone was watching everyone. Now people will watch some more. Because, after all, there is only one October. And all you have to do is be a part of it, and your team has an equal chance of winning the whole thing.

"Once we get to the first part of this (postseason), anything can happen," Cubs WGN broadcaster and former third base great Ron Santo said before the final out in Cincinnati. "Once we're there, I feel very strongly it's like a new season starting."
