Roch Kubatko does a very good job of describing Sidney Ponson's problems this season:

It can be one bad inning or one bad pitch, a struggle to get the last out or one ball in the proper location.

Sidney Ponson began yesterday tied for the most wins among Orioles starters with five, but a 5.94 ERA suggested he has been flawed. Entire outings usually don't go bad for him, just small segments, which can lead to bigger problems.

If you go through his games, you see a number of three-run innings surrounded by otherwise good pitching. He's been farily lucking that the offense has bailed him out:

He usually can expect lots of offensive support, except when Lidle scatters six hits and goes the distance. Ponson's ERA was the sixth-highest in the American League before yesterday, but his run-support average of 8.04 was the fourth-highest.

As an accounting function, wins go to the pitcher. But if there was a way to do it, some of Ponson's victories belong to the offense.
