Wei-Chung Wang doesn't recognize FIP (Fielding Independent Pitching), or does he?

A little dated, but in this interview with Kyle Lesniewski of Reviewing the Brew, he fielded this question about awareness of advanced pitching statistics:

The advanced stats say you may be suffering from some bad luck this season, given your high BABIP rate (.357 despite low 32.8% ground ball and 13.6% line drive rates) and low FIP. Do you look at the advanced stats at all, or do you focus more on the traditional things like wins and ERA?
This was Wang's reply: 

Wins and losses mean little at this level of the minors, so I don’t really pay attention to my win-loss record and I don’t look at my ERA. I keep my focus on the things I can specifically control during the games I pitch, especially walks and home runs. 
So though he did not assent to knowledge FIP, he appears to know that he could only control things like BB and HR, which along with SO, comprises FIP.

Wei-yin Chen and Exit Speed Suppression

FiveThirtyEight.com has an article on exit speed, the speed of the ball as it comes off the bat. Apparently, Chen leads the MLB in suppressing said speed.

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.
