Earlier this week, I posted my list of the top pitchers in the NL and explained my methods.  Just as a recap, here’s what I am trying to do:

1) I start with the number of runs allowed by each pitcher, and the number of innings that guy pitched.

2) I modify the number of runs allowed to account for any bias based on the pitcher’s home park.

3) I modify the number of runs allowed based on my defensive rating system for teams and players because if you have Seattle’s team defense behind you, you are less likely to allow a run than if you had the Royals defense behind you.  We’ll get into this in more detail when we hand out defensive awards next week.

Then, I compare what an average pitcher would have done with what that pitcher did – and come up with a “runs saved” or “extra runs allowed” ranking.  Nobody saved his team more runs than did Zack Greinke last year.  Zack Greinke had a really low ERA over more than 220 innings despite pitching in a park that helps hitters a little bit and having a rather poor defense behind him.  As such, his season is the best season I have tracked since I started doing this in 2005.

Top Pitchers (by Runs Saved)

65.61 – Zack Greinke (KC)
47.11 – Roy Halliday (TOR)
33.22 – Jon Lester (BOS)
32.14 – Felix Hernandez (SEA)
27.55 – Andrew Bailey (OAK)
26.51 – Cliff Lee (CLE)
25.74 – C.C. Sabathia (NYY)
25.73 – Justin Verlander (DET)
22.21 – Jonathan Papelbon (BOS)
21.30 – Mariano Rivera (NYY)
21.13 – Joe Nathan (MIN)
20.80 – Jered Weaver (LAA)
20.57 – Kevin Millwood (TEX)
20.09 – Josh Beckett (BOS)

21.61 – Jarrod Washburn (SEA) – but -13.29 in DET

In fact, it’s not even close – Greinke had as good a season as we’ve seen by a pitcher in a long, long time.  Imagine if he had done this for 40 starts instead of 33, with a team like Seattle.  He MIGHT have had an ERA around 1.70 and a won-loss record of something like 27 – 4.  From this, you can see that Halliday instead of Cliff Lee will be a slight step up for Philadelphia and would have been a more serious contender for the Cy Young Award (in my book) had not Greinke been more dominating.

Another thing of interest – four relievers were good enough to sneak onto the list of pitcher saving his team more than 20 runs, led by Andrew Bailey.  Let’s use that to show the list of the top relievers in the AL last year.

Top Relievers

27.55 – Andrew Bailey (OAK)
22.21 – Jonathan Papelbon (BOS)
21.30 – Mariano Rivera (NYY)
21.13 – Joe Nathan (MIN)
18.41 – Matt Guerrier (MIN)
18.09 – Darren O’Day (TEX)
17.04 – Matt Thornton (CHW)
17.04 – Michael Wuertz (OAK)
16.79 – Darren Oliver (LAA)
16.41 – Jose Mijares (MIN)
16.16 – Brandon Lyon (DET)
15.87 – Joakim Soria (KC)

A couple of things – usually the top guys are middle relievers or set up men with great ERAs in 70 innings.  There are a couple here – Thorton, Wuertz, and Oliver for example.  Still – the top four guys were KILLER closers in 2009.

Worst Pitchers

-37.04 – Andy Sonnestine (TB)
-33.26 – Fausto Carmona (CLE)
-24.16 – Chien-Ming Wang (NYY)
-22.81 – Jason Berken (BAL)
-21.45 – Derek Holland (TEX)
-20.71 – Luke Hochevar (KC)
-21.02 – Chris Jakubauskas (SEA)
-20.38 – Jose Contreras (CHW)
-19.59 – Armando Galarraga (DET)
-19.17 – Rich Hill (BAL)
-18.36 – Garrett Olson (SEA)

-23.47 – Scott Kazmir (TB) – but positive 11.34 in LAA

If you had Andy Sonnestine on your fantasy team last year, you didn’t read my Tampa Rays Team Profile that pointed out that many of the Rays pitchers weren’t as good as you thought because the team defense in 2008 was amazingly good.  In 2009, Bartlett was hurt, and Upton struggled, and Aki Iwamura went down, and Carlos Pena looked a little older (and then left to an injury).  Sonnestine may throw strikes, but they sure do get hit a lot.

Hopefully, Fausto Carmona and Chien-Ming Wang can figure things out.  Two years ago, these guys won nearly 40 games combined – and now they are #2 and #3 on the wrong list.

And, if you are scrolling down to the NL List, note that the list contained a bunch of Brewer and Padre pitchers.  In the AL, only Seattle doubled up by having two guys get pounded around – bad pitching was more evenly distributed…
