SlashLine Splits App for iPhone (Free)

+

Got this link via the mailbag. The app uses Retrosheet data to break down active players' splits (home/away, vs. pitcher, positional splits, etc). The stats won't be updated once the season begins, but it looks well-designed, and heck, it's free. As far as I know, it's just for iPhone/iPod Touch...I didn't see it in the Android Market.
