There is inherent risk in pitchers that young which makes dealing them easier than dealing young position prospects. At the same time - a pitcher striking out almost a batter an inning as the youngest player in all of Low A with 95-99 velocity is pretty darn interesting ... age and performance for level is always noteworthy ... when a team signs a guy for whom the industry brings up "young Pedro" without howls of derisive laughter, you have to pause.
I will not many of the posters will snivel at some future point about the weakness of org pitching and where is the ceiling? I know where the ceiling went.
I am a bit surprised at the Hulk Smash approach taken with a Top 20 prospect and how little track record it actually brought back. Nobody is untouchable, but a big market has the luxury to keep the high ceiling guys ... especially with a vibrant farm system. This deal makes sense for Boston on a basic level - at the same time, San Diego clearly had to be thinking "you're giving us what??!!!"
