Giants Win, Complete Improbable Comeback

A thing of beauty

Two days ago the Giants had just a 15 percent chance of winning this series. This afternoon they became the first National League team to come back from down 0-2 in a five game series.

The big inning was the 5th where the Giants scored all 6 runs and then held on for dear life. All those times putting the tying run on base nearly gave me a heart attack and made it hard to type at times with my hands shaking uncontrollably.

It wasn't easy.

It wasn't pretty.

In the end it really doesn't matter because the Giants won.

Now us fans have a day or two to recover from the stress and nerves before the NLCS ratchets up the nerves to the next level.

Giants odds at 28 percent: Updated NLDS Odds


After an improbable win where the Giants offense took a play right out of the 2010 Padres playbook the Giants season continues to today.

Since I last looked at the odds things have changed quite a bit, with Johnny Cueto out and Mike Leake brought into replace him. Today it is Leake vs. Barry Zito (another change) and if necessary it will be Mat Latos vs. Matt Cain tomorrow morning.

Here is everything updated with the changes since a ran the original projection and the updated odds:

Reds Giants
Game 1 100% 0%
Game 2 100% 0%
Game 3 0% 100%
Game 4 49% 51%
Game 5 44% 56%

And the permutations for the last two games:

Games Reds Giants
3 0% 0%
4 49% 0%
5 23% 28%
Total 72% 28%

It's still a long shot for the Giants but crazier things have happened and amazingly the Giants are actually favored in the last two games (even though they would be better classified as toss ups).

Projecting Giants vs. Reds NLDS



After missing last year the welcome pangs of nervousness have come back with the Giants back in the playoffs.

In the National League Division series the Giants face the NL Central Champion Reds. The Reds are a very good team and this series shouldn't be easy for either team.


Here is the statistical breakdown for each team:

Offense

AVG OBP SLG wOBA wRC+
Giants 0.269 0.327 0.397 0.315 99
Reds 0.251 0.315 0.411 0.314 93

Pitching

ERA- FIP- xFIP-
Giants 97 101 101
Reds 83 93 97

The Giants have the edge on offense, while the Reds have the edge in pitching. Neither edge is huge and at least based on the eyeball test it looks like they might balance themselves out.


Next let's move on to the projection. In case you forgot or haven’t seen the explanation, here is a quick description of how the model works:
  • I start by estimating the runs scored and allowed for each team given the starting pitcher, bullpen, defense and each team’s offense.
  • The data used in the projection model is based on the current season’s statistics to date and if a player has less than a full season of data it is supplemented with the ZiPS projections.
  • The estimated run differential is then converted into a projected winning percentage using the pythagorean expectation.
  • Then, it’s converted into an odds of winning the game using the log5 method developed by Bill James

Probables:

Saturday, October 6, 6:30 PM: Johnny Cueto vs. Matt Cain
Sunday, October 7, 6:30 PM: Bronson Arroyo vs. Madison Bumgarner
Tuesday, October 9, 2:30 PM: Mat Latos vs. Tim Lincecum*
Wednesday, October 10, TBD**: Homer Bailey vs. Ryan Vogelsong*
Thursday, October 11, TBD**: Johnny Cueto vs. Matt Cain

*The Giants haven't announced who will be pitching beyond game 2 but this is my best guess.
**If necessary

Odds:

Reds Giants
Game 1 43% 57%
Game 2 37% 63%
Game 3 49% 51%
Game 4 44% 56%
Game 5 48% 52%
The Giants are favored in every game with games three and five coming out at just about toss up games. The big thing that drives the advantage is the Giants run scoring of all things, if you went back and told that to ourselves last year we would think we were crazy.

The Reds have the pitching advantage in every game expect for game 2, where Bumgarner has the edge on Arroyo who is the Reds worst starter of the four. In addition the last thing the Giants want to see is the Reds bullpen so getting out to a quick start will be even more important.

Here is how the different permutations turn out for the series with the odds of each team winning in a certain number of games:

Games Reds Giants
3 8% 19%
4 14% 24%
5 17% 19%
Total 39% 61%
The Giants starting at home really helps with the series. The chance of a sweep for the Reds is very small while the Giants have nearly a one in five chance at the sweep.

If the Giants are able to take the first two games of the series they push their odds of winning to 90 percent while a split at home makes it into a 50/50 proposition.

As reassuring these numbers are, this is still a short series where random fluctuation can cause havoc, at the very least the Giants have the benefit of starting at home to try to build a commanding lead in the series.

Comparing the 2010 and 2012 Giants teams



Over at Bay Area Sports Guy I wrote up a post comparing the 2010 and 2012 teams. I was pretty surprised that the 2010 team came out ahead but maybe I shouldn't have been with the superior pitching.

Here is the conclusion. Check out the full post for the whole thing.
Cumulative Fangraphs Numbers2010 Giants hitting (fWAR): 32.52010 Giants pitching (fWAR): 18.42010 Giants fielding (UZR): 60.72012 Giants hitting (fWAR): 28.82012 Giants pitching (fWAR): 15.42012 Giants fielding (UZR): 0.0 
One thing to note: based on Ultimate Zone Rating (UZR), the 2010 Giants were the best defensive team in Major League Baseball. In 2012, they started out so badly that they’re going to finish the year right in the middle of the pack. We’ll just have to wait and see if defense becomes an issue this October. 
Overall, the 2010 Giants might have been a little bit better based on the strength of that team’s pitching staff, but I think that the 2012 offense could hold their own with the 2010 team.
