Baseball Prospectus' Kevin Goldstein has his Top 11 Boston Red Sox Prospects up. There is no surprise with the top two players, but sinkerballer Justin Materson at #3 may be more eyebrow raising. He struck out 115 in 153.2 innings of work between AA and AAA. That is not the ratio I normally associate with major league success
However, I suspect the high-profile success of the Yankees' Chien-Ming Wang and the Indians Fausto Carmona has made the groundball-inducing pitching prospect a more attractive option for long-term success.
I do wonder if this is the discovery of a new market inefficiency or a mistake of using the success of a non-representative sample to make an incorrect valuation.
