I'll go with my favorite NL team the Cardinals with rookie 3B David Freese. David has been clutch so far this season wih runners in scoring position. The concern with him was defense coming into the season and he has really done well even making rolen-like barehanded plays.

For my AL team the Rangers, I'd have to say Vlad Guerrero.... .339 batting average, 12 Hrs and 42 RBI's....the numbers speak for themselves. Glad to see him injury-free again.
