Phillies DIPS

While responding to dajafi's Kendrick post, I decided to look at the DIPS ERAs for all the Phillies pitchers. For those unaware, DIPS stands for defense independent pitching stats and was coined by Voros McCracken at the tail end of last century...so get read up. While not the perfect of all stats, it certainly gives an idea what a pitcher would be doing if luck had no role whatsoever.

Player Name ERA DIPS DIPS%

JC Romero 2.27 4.51 1.99

Chad Durbin 2.15 3.20 1.49

Brad Lidge 2.10 2.61 1.24

Jamie Moyer 3.64 4.28 1.18

Ryan Madson 3.16 3.71 1.17

Cole Hamels 3.22 3.68 1.14

Clay Condrey 3.60 4.03 1.12

Kyle Kendrick 5.01 5.15 1.03

Brett Myers 5.02 5.16 1.03

Adam Eaton 5.80 5.15 0.89

These numbers don't bode well for the Phils. Even Myers and Kendrick are showing to be a little lucky. Romero is living up to his initials. I would have thought Moyer to be a bit higher though.

Let's hope that the luck continues to flow.

With the relievers I think you have to take into account that, especially in Romero’s case, they only come in for one or two outs, so there’s less “time” for their baserunners to score and count against them as earned runs.

But your premise is right. We needs some more strikeout pitchers, plz.

What do Myers’ DIPS look like since his return?

Does this mean that Eaton has been unlucky?

Is it meaningful to compare DIPS ERA to actual ERA for individual pitchers?

If I am understanding DIPS ERA correctly (a big if) then it can be used to compare between pitchers because it fills in the rest of a pitcher’s line (everything but HR, HBP, BB and K) based on the league averages.

If that is so, DIPS ERA will take out pure luck and actual defensive performance and maybe park environment. I don’t know if, or how, it takes account of park effects.

Could the DIPS differences for the Phillies’ pitchers just be a systematic effect indicating they are playing in a small park (more HR, fewer doubles and triples) with a good defensive team behind them?
