The Yankees were one-hit by the Athletics second best starter yesterday, and today they face the A's best. Dan Haren brings his 1.91 ERA to the Bronx as he takes on Andy Pettitte. Haren is just the kind of pitcher who should be successful against the Yankees; a righty who mows down lefties. The A's should probably put all their lefties in against Pettitte as they are hitting .302 off Pettitte this year.

Down the road in Baltimore, there's another great pitching matchup as John Lackey faces Jeremy Guthrie. Lackey ranks fifth in the AL in ERA. Despite calling a pitcher's park home, Lackey's record is better on the road this season where he has a 2.41 ERA. In a pretty impressive month for ERAs, Guthrie ranked fourth in the majors with a 1.69 mark in June.

The Mariners are depending on Jeff Weaver to keep their winning streak alive. Despite his high ERA, Weaver's pitched well since coming off the DL, going 2-0 with a 1.82 ERA in four starts. Shaun Marcum tries to end the streak. He gives up more hits on the road, but only half the home runs.

Enjoy!
