Great Sabermetric and Pitch f/x Writeup on Wei-yin Chen

Great sabermetric and pitch f/x writeup on Wei-yin Chen's improvement over prior years, with a higher groundball rate, an only slightly lower K rate, and very few walks. The analysis is much better than this goofy piece from Chen's rookie season. The latter is basically saying that Chen got batters to whiff on strikes high up in the strikezone, pitches that usually go for homeruns. Donut3 in the comments section sarcastically remarked, "Extreme flyball pitcher pitching in Camden with a tiny HR/FB percentage. This will definitely last." Indeed, Chen's HR rate soared.
