They have an average number of games in relief, but check out their inherited runner stats. They have inherited a pretty small number of runners (which may be due to the strength of their starting pitching as well as how the relievers are used) but the have allowed a tiny percentage, just 15% to score. That's incredible.

So the Padres bullpen has:

  • the best ERA, by a lot
  • the fewest walks (tied with Colorado)
  • the most strikeouts
  • the best K/BB ratio by a country mile

Excellent stuff. Given that their starting staff is also very good and is about average in terms of innings pitched per start, the bullpen hasn't been overworked so far and might just hold up through the rest of the season.

  1. I really like the IS% stat, although I wonder if there is a way to break it down further. Obviously, it's not quite as impressive when entering a game with two outs and a runner at first as it is when entering a game with no outs and the bases loaded. If we take some middle ground like "runner(s) in scoring position with less than two outs", would the Padres pen still be the leader in IS%? Would the sample even be large enough to matter?

  2. JDV,

    A nice way to take into account the situation for relievers is Win Probability Added, or WPA/IP if you want a rate stat.

  3. Johnny Twisto Says:

    Padres relievers Luke Gregerson and Mike Adams, neither of whom I've ever heard of, lead the majors with 17 holds each, both on pace to shatter the hallowed record of 36, held by Scott Linebrink and Tom Gordon.

    You can see that the Padres' bullpen has an above-average aLI (average Leverage Index) which means that their relief appearances have been, on average, a little bit more important in terms of game outcome. You can see that they have had more high-leverage and medium-leverage situations than league-average, and fewer low-leverage situations than league-average. They've had an above-average Save% too.

    Any way you slice it, their bullpen has been very, very good so far this year.

  5. Holy Rattlesnake Batman! Arizona's bullpen has been awful!

  6. Some of SD's good numbers must be from their home park, including the higher aLI. (When you pitch in a lower scoring environment, you are more likely to have close games.) This early in the season there may be larger variations in quality of opposed batters also. Could check away games to see if this just a park produced mirage. (Though that would lead to greater sample size issues.)

  7. Sick, sick pen. Gregerson was insane against the Mets a bit ago. I think over two series he struck out six or seven of the ten or eleven batters he faced.

    They can't trade A-gon now, can they?

  8. maestro876 Says:

    @Kds: There are plenty of park-adjusted stats that show it's not a mirage created by Petco.

  9. Kahuna Tuna Says:

    2010 Padres bullpen, home vs. road:

    At home: 9 W, 4 L, 6 Sv, 130.3 IP, 92 H, 36 ER, 30 XBH allowed, 142 TB allowed, 32 BB, 147 K, .199 BA, .254 OBP, .307 SLG, .561 OPS, .270 BABIP, 0.951 WHIP, 10.2 SO/9, 4.59 SO/BB.

    On the road: 3 W, 3 L, 11 Sv, 94.3 IP, 75 H, 29 ER, 27 XBH allowed, 119 TB allowed, 30 BB, 94 K, .216 BA, .283 OBP, .343 SLG, .626 OPS, .271 BABIP, 1.113 WHIP, 9.0 SO/9, 3.13 SO/BB.

    Heath Bell's home ERA is 3.52, and his road ERA is 0.69.

    This bullpen is not merely a creation of Petco Park.

  10. Wow, what an eye opener. I had no idea SDP were doing so well in this regard.

  11. "They can't trade A-gon now, can they?"

    Definitely not, but their bullpen is so deep and so good that they might want to see if they could trade Heath Bell for a decent bat. They could use another good hitter to help Gonzalez out a bit. The SD offense is pretty much a one-man show.

    The most eye-popping SD bullpen stat of all is probably Luke Gregerson's K/BB ratio: 43 strikeouts against just two unintentional walks in 35.2 innings. Just insane.
