Did Doumit's pitch-framing cost the Twins 3.8 wins?

I was perusing Fangraphs and saw an article about the end of the Doumit catching era. According to the article, Doumit was/is the worst pitch-framer ever. -3.02 strikes per game: http://www.fangraphs.com/blogs/tradi...end-of-an-era/

According to the same article, one call is worth .13 runs. And, if I understand correctly, 10 runs is roughly 1 win.

So Doumit caught 99 games for the Twins total. 99 games x 3.02 runs per game is 298.98 lost strikes. That equates to 38.8 runs, or nearly 4 wins total.

Just though it to be interesting. Does anyone buy this math?
