The top two teams in the American League square off tonight in Boston as Nate Robertson faces Daisuke Matsuzaka. Robertson comes off his first poor start of the season. He allows a high number of balls to be put into play, and it didn't pay off against the Mariners. Matsuzaka continues to pitch better than his ERA. He's dominating lefties, who are batting .215/.311/.316 against him. Despite an ERA close to five, the Red Sox should be happy with their investment in the pitcher.

Two former Braves face each other at Shea as Jason Marquis takes on Tom Glavine. Marquis's 1.70 ERA sits third in the National League. Coming into tonight, opponents post a lower slugging percentage than OBA against Marquis. In a year with home runs down, Glavine's allowed seven, but five of those came with the bases empty, limiting the damage.

The pitchers ranked two and three in AL ERA oppose each other in Oakland tonight. Meche and Haren hooked up five days ago. Both pitched well but neither figured in the decision. In sixteen games (15 starts) against Oakland, Meche is just 2-7 with a 4.34 ERA. Haren is another righty who is dominating lefties this year. The group is hitting .168 against Dan with a .218 OBA.

Enjoy!
