I like Eckstein too.
He's hitting leadoff in what is perhaps the AL's most potent offense outside of Boston/New York.
Lugo's a decent option as well, but Piniella likes to jack around his lineup alot so there's no guarantee he'll bat 2nd - where he had the most success last year. He hit 7th both games in Japan.
I think Eckstein's a better bet for Avg, R, and SBs.
Lugo will definitely give you more HRs and RBIs.
I think its close, but I'd take Eckstein.
