Sep 30, 2009, 4:18 PM EDT

Minimum 50 innings. Listed along with each pitcher’s ERA are saves+holds and blown saves.
1. George Sherrill – 1.75 – 32 – 5
2. Trevor Hoffman – 1.76 – 36 – 3
3. Mariano Rivera – 1.82 – 44 – 2
4. Jeremy Affeldt – 1.84 – 33 – 0
5. Kiko Calero – 1.86 – 12 – 4
6. Andrew Bailey – 1.88 – 28 – 4
7. Jonathan Papelbon – 1.91 – 37 – 3
8. Darren O’Day – 1.93 – 22 – 0
9. Ryan Franklin – 1.95 – 39 – 5
10. Jose Mijares – 2.07 – 27 – 1
11. Jose Valverde – 2.08 – 26 – 4
12. Ronald Belisario – 2.09 – 12 – 7
13. David Aardsma – 2.10 – 42 – 4
14. Francisco Cordero – 2.19 – 39 – 4
15. LaTroy Hawkins – 2.20 – 30 – 4
16. Joe Nathan – 2.25 – 45 – 5
16. Joakim Soria – 2.25 – 29 – 3
18. Matt Guerrier – 2.33 – 32 – 3
19. Mike Gonzalez – 2.45 – 27 – 7
19. Brian Sanches – 2.45 – 8 – 3
These aren’t baseball’s top 20 relievers this season, but the top 10 or so are all in the mix here.
So who has really been the best? I see three possibilities. Rivera absolutely has to be considered, given that he’s blown just two of his 46 chances. But how about Affeldt? He’s made 72 appearances this year and hasn’t blown a single lead.
And then there’s candidate No. 3: Bailey. The big plus in his corner is that he’s thrown 81 1/3 innings, compared to 64 1/3 for Rivera and 58 2/3 innings for Affeldt. Also, he hasn’t allowed an unearned run all season. Rivera has allowed one and Affeldt two, so Bailey has them beat when you drop the E from ERA. Bailey has blown four leads, but he actually allowed a total of two runs in 5 1/3 innings in those games. Plus, he has six wins, more than Rivera (three) and Affeldt (one) combined.
I’d say it really comes down to Rivera and Bailey, and while you can argue that Bailey’s performance was more valuable, there’s still no doubt that Rivera is the reliever everyone wants protecting that one-run lead in the ninth.

    I realize Phil Hughes, does not have the required numbered of IP to qualify here….but to overlook his numbers in the pen is a mistake. Look them up.

  2. Matthew Pouliot - Sep 30, 2009 at 4:55 PM

    Whoops. I didn’t realize he was up to that many innings or I would have changed the requirement. I thought he was still around 40.
    For the record, Hughes has a 1.27 ERA in 49 2/3 innings out of the pen (2.99 in 84 1/3 innings overall). Also, he has 21 saves plus holds and three blown saves.

  3. Church of the Perpetually Outraged - Oct 1, 2009 at 8:35 AM

    He pitched again last night so his stats now are:
    50.2IP, 0.81 WHIP, and 1.24 ERA
    Can’t wait to see him in the starting rotation next year.
