Around SBN: Win or Lose, Boston Celtics' New Big 3 Era A Success

Welcoming the Second Wild Card (and the Astros)

In the future, this could have "the playoffs" affixed to the end

The Seattle Mariners will have had 18 (since no playoffs in 1994) opportunities to win a four-team AL West when the 2012 season concludes. As of now, they've accomplished that feat three times in 17, one below their theoretical expected number. Good job, Mariners, you're even bad compared against abstract mathematical reality. The division will inflate to five teams starting in 2013 and with that so goes the built-in advantage of fewer competitors that the Mariners have enjoyed, but not really seized, for almost two decades.

However, that's coming to an end with the move of the Houston Astros into the division and the expansion of the playoffs to two wild cards. All that really matters of course is how this affects the Mariners. Who cares about anything else?

As I just recently (very recently) explained here on FanGraphs (go there to read though each team's current probability), in 2012, the Mariners will begin the season with a 31.8%* chance at the playoffs. It's been that way since the switch to six divisions which means they should have been expected to see six trips, all things being equal. Instead we saw four. Great job, Mariners, you look even worse now!

*Each AL West team has a 25% chance at an automatic berth and then a 75% (since they can't win both) chance at a wild card shot, which carries a 9% (1/11) probability. 0.25*1 + 0.75*1/11 = 31.8%. The formula comes from Bayes' theorem.

The odds of winning the division crown fall to 20% (1 in 5) starting in 2013, but baseball is adding a second wild card to the mix. For the Mariners (and for all 29 other teams), that means their level-playing-field probability will then be 33%*. Adding the Astros and a second wild card team actually increases the Mariners' (and Rangers' and Athletics' and Angels') odds of meaningful October play by a very slight margin.

*1 in 5 x 1 + 4 in 5 x 2/12

For those disgruntled Astro fans, they might want to heed this post as well. Their club, stuck in the six-team NL Central and 16-team National League currently face the worst level odds in baseball at just 23.1% each season. Their move to the AL helps grant them an increase of almost 10%.

This second wild card...

still pisses me off a bit. I’m not sure if it has been discussed here at any length, but it seems pretty clear to me that the more you expand the playoffs the more you de-value the playoffs. The easier it gets to make it in, the less special they become. I’m thinking of teams like the Lakers or the Red Wings, who both play in leagues where half the teams make the playoffs and both fan bases just expect to get in. Even as dominant as the Yankees have been, their fans seem to feel privileged to make the playoffs, rather than entitled to the playoffs.

There is a lot to think about, and I haven’t thought about it too thoroughly yet, so I’m all ears (eyes) if someone wants to explain why two wild cards is good. Maybe I’ll wind up liking it in the end, but part of what makes the playoffs so special for baseball is that it is so tough to get into them in the first place.

Wow

Somehow, I’ve never found people who dislike the playoffs entirely. The usual opinion is "regular season dominance is very good, but . . . ". I’m glad to see this.

I didn't say I dislike them entirely.

I said I don’t care in reference to zeeehjee’s worries about the playoffs being less special due to exclusivity. I find playoffs to be an irrational way of determining a champion so I don’t much care what form they decide to use. Might as well go for maximum entertainment since fairness is out the window

Got it, and that's pretty much what I meant too

I found the playoff system very strange the first time I encountered it. I was used to European football leagues, where, of course, there’s a separate cup competition and league competition occuring simultaneously.

Maybe it’s just the people I’ve encountered, but the regular season is often discounted too heavily for my liking. I can’t think of many practical solutions, though, short of two 15 team leagues with one pennant each to fight for. That would never happen, but it would be marvellous.

We're getting close to that.

Just need a balanced schedule once the Astros move and you could declare the best AL and NL records to be the de facto pennant winners for the season

There's the cool part where winning the division means a lot more than getting a wild card spot.

Then there’s the uncool part where the second best team in all of baseball (literally 2nd of 30) could get knocked out of the playoffs in one game in the RO10.

Remember how awesome the last day of the season was?

If there were two wild card spots, it wouldn’t have been nearly as awesome. Right?

I feel like Charlie Brown trying to kick the football. Ugh

by HitKing69 on Nov 17, 2011 10:59 PM PST up reply actions  

I disagree

If we had this system in place last year, all four teams playing for the playoffs on the last day of the season would have already clinched. It wouldn’t have mattered at all.

Perhaps I'm mistaken and I know I will be corrected if I am

But weren’t the Red Sox/Devil Rays playing for the final wild card in the AL and the Cardinals/Braves were playing for the final wild card in the NL on the last day of the season?

Under the current plan, all four teams would have gone into that final day having clinched wild card spots, correct? No drama, no excitement? Or am I missing something?

You are missing that under the new system, the two wild card teams then play a one game series

to move onto facing he division winners. Ergo, every year will see what is, in essence, two one-game playoffs.

by Matthew on Nov 20, 2011 10:30 AM PST up reply actions  

Got it. I missed that point entirely

Also, it's not a very compelling argument.

So it might have made this year less dramatic maybe (no actual way to know since the addition of 2nd wild card changes how teams would’ve made decisions far back), it also would have made other years more exciting.

by Matthew on Nov 20, 2011 10:32 AM PST up reply actions  

If the Mariners get into the playoffs in the near future because of the 2nd WC spot, I won't care one bit that a couple years prior, that playoff trip would not have been warranted.

If that makes sense.

In 2003, the Mariners won more games than two division winners (Minnesota and Chicago Cubs) and had there been a 2nd WC spot, we would have gone to the playoffs. I never complained because that’s the way the Division System works. If there had been two wild card spots that year though I would not have felt like we didn’t belong there. One extra playoff spot does not make it any less special in my mind. It allows teams and their fans that don’t often get the opportunity to experience that special feeling an extra chance to do so.

I'm only curious about what's really important:

What kind of godawful home&away uniforms will the Astros be wearing in ’13?

I'd prefer the Marlins over the Astros

Does having the Astros in our division really hurt out play off odds? I mean we always complain about not being able to face the Mariners horrible offense, and now we get to! I think having the Astros join our division means less Angels and Rangers.

What?
Does having the Astros in our division really hurt out play off odds?

No. That was… that was the point of the post. Our playoff odds are going up!

by Matthew on Nov 17, 2011 10:59 PM PST up reply actions  

I guess my point isn't well thought out

I just assumed having the Astros in our division would mean us having to face the Angels and Rangers less. If the number of division games against the other AL West teams don’t change it at least means we face the rest of the AL less. The Astros aren’t a very good team and I guess that could change in the future. I guess my argument is invalid.

"If the number of division games against the other AL West teams don’t change"

The number of division games against the other AL West teams do change. From 19-20 per season to 18. Not a big change, but it is a change.

I prefer the Marlins as well...

Back to the Future has been right about so many things––a 2015 Cubs vs. Marlins World Series sounds inevitable. I mean, they’ve already changed their name to the Miami Marlins.

I was looking forward the last week to two one-game playoffs...

…Red Sox/Rays and Cardinals/Braves. Now we’re guaranteed two elimination games to start the playoffs. Don’t tell me you won’t be watching those!

Is there a ripple effect now, due to the effect of which pitcher is used by the wild card one-game-playoff teams?

Lining up rotations for the last week of the regular season, for teams that have a shot at the wild card, will probably give some managers migraines. Do you put your ace out there for the one-game playoff? Or do you trust someone else to do well enough for that, that you can line up the ace for the presumptive start of the 5-game division series the day after?

And then, suppose a team panicked (or just had no choice, due to rotation depth or injuries) and shoved their ace in there for the one-game playoff. If that WC team doesn’t have a solid rotation, they’re a huge mismatch against whatever division winner they face, as they’ll be going with their #2 and #3 pitchers, with their ace only able to pitch once for the whole series, and on 3 days’ rest at that.

So if anything, the second wild card might have nerfed the wild card altogether, and made it that much better for the division winners, as they can optimize their rotations for the whole playoffs.

This is assuming that there’s a measurable dropoff, on average, in the quality of starting pitcher from #1 to #2, on the pitching staff of your average wild card team. I don’t know how to quantify that, given how recent the wild card is.

Also, the articles on “who would have been in a one-game playoff if we had this 2nd wild card for a decade”, don’t indicate that any .500 team would be making it to this. So perhaps if a team is good enough to win 87, 88ish games, it’s got a rotation deep enough to still match ok against teams that won 93 games but just played in a division with a monster.

And of course this assumes that much of anything can be done, with any pitchers or position players, to make a huge difference for a team’s odds in a best-of-5 series.

This doesn't even take into account...

that, at least for a year or two, we’ll get several extra games against a terrible opponent, which increases our chances of winning the Wild Card in and of itself.

Not that it really matters, but...

Bayes’ rule is for conditional probabilities. Your formula is the law of total probability: P(playoffs) = sum_{win division} P(playoffs | win division) P(win division).
