I have finally joined the 2008 and got on Twitter. I cannot promise anything great Troy Polamalu Jersey from my feed, but I like how easy it's to follow baseball news and browse other analysts pa sing thoughts. It has repaid by means of the idea with this post. This morning Sky Kalkman tweeted: Andy Sonnanstine: trade bait, rotation candidate, bullpen filler, or AAA veteran? I had kind of forgotten about Andy Sonnanstine, but the tweet reminded me how much of an interesting pitcher he's. Sonnanstine was worth over 3.5 wins for that Rays in 2008, but then things fell apart in 2009. Part of that was bad luck on his BABIP and HR/FB, but some of it seemed to be according to his performance. Sonnanstine doesnt strike out many batters or get that many ground balls, so he must have a great walk rate to succeed. That is what he did in 2008 walking just 1.7 but in 2009 it increased to three.0, erasing much of his value. The increase of walks was not from mi sing the strike zone his pitches were in the Charles Woodson Jersey zone as much but, rather, from batters swinging le s often at his out-of-zone pitches. Here are the ones numbers by pitch type: O-swing O-contact 2008 2009 2008 2009Fastball 0.23 0.23 0.83 0.80Cutter 0.22 0.19 0.73 0.72Slider 0.40 0.35 0.55 0.69Curve 0.29 0.26 0.57 0.86The rates on his fastball were e sentially the same, but for his cutter, slider and curve the O-Swing rates were way down. This turned many more plate appearances into walks. Another serious problem could be that the O-Contact rate on his slider and curve were in place, although this was not accountable for the increase in walks it does show these pitches were easier to hit. Interestingly Sonnanstine also threw his cutter a lot more often in '09. According Dane Sanzenbacher Jersey to my pitch cla sifications, it went from 28% of times in 2008 to 44% in '09. Mostly this change came at the cost of his fastball which went from 35% to 24%. It might be that hitters fare better on the cutter having seen it more regularly or since they're expecting it. But I do not see evidence for this on an at-bat level. That can there be wasn't any trend for batters to do any better on the second or third cutter they see in an at-bat than the first cutter they see in at-bats against Sonnanstine. Getting to Skys question, I believe I would take a little from column a, a little from column b and a little from column c. That is start him off within the pen like a long reliever since the Rays have five better starting options however with the eye to trading him if anything of worth arrives or moving him to the rotation if needed. Cassius Vaughn Jersey He includes a relatively small platoon split, doing fairly well against LHBs, so deploying him as a long reliever will be a nice method to leverage that talent. Also his very deep repertoire of pitches plays along with an extended reliever where he may have to face batters multiple times. These skills also mean he might be much better suited like a starter if he is able to get things together again, that might mean throwing his fastball a bit more often.
