As a group, Phillies relievers combined to throw 483 innings in 2008 and were charged with 191 runs.

Here’s how many innings each pitcher threw in relief, how many runs they were charged with, the percentage of the team’s relief innings that were thrown by that pitcher, the percentage of the relief runs allowed by that pitcher and the difference between the percentage of innings he threw and the runs he allowed:

Player IP RA % of IP % of RA Diff
Chad Durbin 87.7 33 18.2 17.3 0.9
Ryan Madson 82.7 29 17.1 15.2 1.9
Brad Lidge 69.3 17 14.4 8.9 5.5
Clay Condrey 69 26 14.3 13.6 0.7
JC Romero 59 18 12.2 9.4 2.8
Rudy Seanez 43.3 24 9.0 12.6 -3.6
Tom Gordon 29.7 19 6.1 9.9 -3.8
Scott Eyre 14.3 3 3.0 1.6 1.4
Les Walrond 10.3 7 2.1 3.7 -1.5
JA Happ 8 7 1.7 3.7 -2.0
RJ Swindle 4.7 4 1.0 2.1 -1.1
Adam Eaton 3 3 0.6 1.6 -0.9
1 0 0.2 0.0 0.2
Kyle Kendrick 1 1 0.2 0.5 -0.3

If you arrange the group by the difference between their percentage of innings thrown and runs allowed from best to worst, the list goes like this: Lidge, Romero, Madson, Eyre, Durbin, Condrey, Carpenter, Kendrick, Eaton, Swindle, Walrond, Happ, Seanez, Gordon.

If Durbin, Madson, Lidge, Condrey and Romero were all to throw the same number of innings in relief in 2009 as they did in 2008, that would put the Phillies at 367 2/3. Eyre threw just 14 1/3 innings for the Phils in 2008 — he seems sure to give them more this year. Over the past three seasons, he’s thrown about 46 innings a year on average. That puts the Phillies at about 413 2/3 innings for the year. It leaves, if the Phillies as a team were to throw the same number of innings in relief in 2009 as they did in 2008, with about 69 1/3 innings that will be need to be thrown by someone else. Again, if everyone stays healthy, Chan Ho Park seems like the guy the Phillies will be going into the season hoping to pitch those innings, picking up many of the ’08 innings thrown by Seanez and Gordon.

Sounds like a plan, if everybody stays healthy. They won’t, of course, so the biggest challenge for the Phillies pen might be figuring out what to do once they don’t.

First day of arbitration filing for those eligible, including Phillies Hamels, Howard, Werth, Victorino, Madson, Blanton, Durbin and Dobbs. The filing period ends January 15 and the hearings will be held between February 1 and February 21.

This suggests the Rays will sign Pat Burrell to a two-year, $16 million contract. This suggests that Burrell turned down two years, $22 million from the Phillies at the end of October.

Update 1/6/09: News from late last night suggests that Romero will be suspended 50 games for use of a banned substance. Romero denies wrongdoing.
