Sports books (fiction or non-fiction)

[Julio]

Oldschool hockey..."Scrubs on Skates" and "A Boy at Leaf's Camp" by Scott Young.

Another book by Kinsella is "The Iowa Baseball Confederacy". I haven't read it since I was a kid, but I remember absolutely loving it.

Ken Dryden's "The Game" is pretty good as well. Not a fan of Dryden's but it is good nonetheless.

"Moneyball" as others have mentioned.
