In a scheduling quirk, the Red Sox make their first trip to Camden Yards this season, roughly two months later than usual. But they are in a familiar spot when they get here today - leading the American League East. The teams have played just one series this season, a Red Sox four-game sweep at Fenway Park in April. The Orioles have had a winning record against the Sox just once in the past 12 seasons. The Red Sox will be bringing an old face to Camden Yards in a new uniform. Likely Hall of Famer John Smoltz will be making his second career start for Boston on Tuesday. A healthy Smoltz could help boost a Red Sox rotation that has uncharacteristically struggled. Their rotation is ranked 11th in the American League in ERA. Fortunately for them, their bullpen, anchored by Jonathan Papelbon, is the league's best. Offensively, the Red Sox are led by outfielder Jason Bay, who was acquired last season to replace Manny Ramirez. The steady Bay has provided top power numbers without the drama that accompanies Ramirez. Bay is leading the league in RBIs and is in the top five in homers. Designated hitter David Ortiz is starting to show signs of life, with four homers in his past 10 games.
