I'll also clarify, sizes differ from manufacturer to manufacturer, Wilson seems to run a bit smaller than Rawlings in my experience. Most SS will play with a 11.5", bigger guys 11.75". 2B go 11.25"-11.5", Pedroia went to 11.75" this year, but his glove wears smaller. 3B mostly 11.75"-12", think Kris Bryant uses 12.25". All of this is why it's best to find something that he has had his fielding hand in. Wilson A2000 and Rawlings HOH are great, durable, quality gloves for the price.
