2010 is still young, even in infancy. So I'm not too excited about Carlos Silva's performance -- pleased, happy, and aware today's game was against the Astros. So, assuming this success is for real, what, if anything has changed? So far, and this is also "too early to rely on", his pitch selection.
Silva throws a sinker (F2), a slider (SL), a change-up (CH) and four-seam fastballs (F4). He still does, mostly 2 mph slower than in 2007, but the 2010 mix is quite different. 
After another start (or two), I'll check again, break things down by count, and share some historical metrics on his four pitches. Regarding those metrics (run values), in a nutshell, the heater/slider increase to lefties makes sense, as does the change-ups to righties. But the change-up to lefties hasn't been effective in the past. That's all in context, which has changed. Perhaps the change will become more effective, for example.

In his first start, he got a lot less in-zone contact than in past years, which I think may be the biggest reason for his success. I wonder if the change, whose value has skyrocketed according to fangraphs (caveats apply), is getting more whiffs.
