Would reinforce the recommendation to try a teammate's glove. The patterns won't have changed and he can order the same brand/model. It will be the "tool of his trade", make sure it's everything that he wants and needs. Given his size and the fact that he just found out about the positional opportunity I would surmise that he may be a versatile player that could also see time at 3rd, that being said look at 11.75/12" gloves.
