Slate gave it a really, really good review:

The reviewer is right about it being a bit confusing for people who don't know racing- my husband said he was confused by some of the dialogue. I like that that it's not being dumbed down, though. I thought the line about risking "$864 on a single in the 4th" was a clever way of doing a bit of exposition.
