Do I think it was smart?
By smart you mean what? Was it the best decision for the team, the player, or his baseball career.
Obviously the team was better with him in the lineup.
Secondly, he obviously handled the task extremely well.
However, the question of course is injury. If he is not strong enough (in shape, durable, healthy) to handle the task, then obviously its a bad decision. On the other hand, if he was all those things then it was merely another day in the ballpark. Personally, I have no idea what his workout regime is, I'm sure his coach does however.
My earlier comment was regarding the "scandal" that happened six years ago when he was 12 and threw 2 games in a day as well as caught 2 games. I remember the outcry that TRhit made, and have yet to see it come to fruition.
This is all beyond the point, however, as the initial point of the thread was to wonder how Stock will wind up as a player, using how he has performed so far as indication. After this weekend he is batting .333 through 20 starts (in 20 games) and has thrown 4 scoreless innings and struck out 8.
