St. Louis at Washington

Jason Marquis has been a dissapointment this season posting a mere 14-12 record with a 5.86 ERA. On the road he's .500 and over his last three starts he's got a 7.31 ERA. He's 3-3 in nine appearances vs. the Nationals and the last time he faced them, he was hit for 7 runs in five innings. Ramon Ortiz has been no better for Washington but this is a home game for the Nats. They are a winning home team while St. Louis is a sub-.500 road team. They are 2-8 during the second half of the season on the road vs. teams that outscore their opponents by 0.5+ runs per game. Over the past two seasons, Marquis is 3-14 vs. such teams. Nationals here.
