This has happened with several of the guys viewed previously as power arms. Surely a move from the bullpen to the rotation will drop some velocity and a move up from Rookie League will lower the strikeouts, but I too am disappointed how significantly the strikeout numbers have dropped. From last year's draft Baxendale, Duffey, Rogers and Powell have all seen a huge drop in strikeouts, I would assume velocity is a factor. From the 2012 draft Boer, Boyd and Summers have also not lived up to their power arm hype. I won't pile on just yet and say the Twins are intentionally doing something that causes this to happen, but this is a trend, not a coincidence, I'd like to find out what the issue is. Considering that none of these guys are able to keep a reasonable strikeout rate and considering most were billed as power arms, one would have to think the Twins are either incorrectly evaluating pitchers that can sustain high strikeout numbers or they are changing the approach or technique of these young men.
