Over his last 11 starts Arroyo has had a very clear pattern of 2 good starts followed by a mediocre/crappy one. He is coming off of consecutive starts where he's only given up one run, including the Reds first complete game on the season on Tuesday. Hopefully his recent trend won't continue as it'd be nice to see the team win 3 in a row, even if it is against the Giants rather than one of the front runners.
As for Arroyo, outside of three terrible starts where he didn't even give his team a chance, he's had a respectable season. I'm not suggesting that we eliminate those three starts from his evaluation. Just saying that I'd rather have a pitcher like Arroyo that sucks ginormously in just a few starts and pitches well the rest of the way than someone with the same numbers who is consistently giving up 4 to 6 runs every start. A pitcher like Arroyo can make for a very good 4th starter in next year's rotation.
Speaking of next year, a loss today or a win by the Cubs means that winning the division will officially have to wait until next year. I know some of you are still holding out hope.
