I've got a much more detailed write-up of today's match-ups and ratings posted at The Hardball times today, but in short:
-Cubs hitters(especially speedy ones, since they're facing Chris Young) have a good match-up, but there's a risk of rain for the game.
-The Indians tandem of Lee and Wood top my pitcher rankings on a very weak day for pitchers, but are also at risk of getting rain. Pettitte and Nolasco are the next best options.
-Pujols is the best by a wide margin at first base, but if you can't afford him, then Helton is a great bargain.
-Rangers hitters have a good matchup.
-Astros hitters have a good matchup...especially for basestealers, since they're facing Jason Marquis.
