Well of course I couldn't possibly resist talk of shortstops without poking my head in to take a peek!
...and perhaps add in my own two cents
Being a third year hs varsity ss, my son has played many positions during his Fall and summer tournament teams in addition to his favorite spot.
While he was resistant at first, I now think he realizes that he has gotten alot of first hand experience being a utility player and thus, perhaps has a broader knowledge of the game. I believe he feels this has been an advantage for him, although he too was worried in the beginning about not consistantly training in one position. So far, so good! ( all fingers crossed!)
The key of course, is to play any ( and all ) position (s) well and to be a good hitter!
I'm a strong believer that you have to have both.
Good luck Johnny!!! Hope you have a great season, and play hard!!!
