Seattle went an impressive 5-4 on its just-completed road trip, on which it played three of baseball's best teams, the Los Angeles Dodgers, New York Yankees and Boston Red Sox. The Orioles and Mariners played six games in June with Seattle winning four. However, the Mariners will have a different look as starting infielders Adrian Beltre and Yuniesky Betancourt are on the disabled list and outfielder Endy Chavez is out for the season with a knee injury. Erik Bedard, the Orioles' former ace, will make his return to the Mariners' rotation Tuesday after not having pitched since June 7 because of left shoulder inflammation. Bedard allowed just one run in 6 1/3 innings against the Orioles on June 2. If he's healthy, Bedard will strengthen a pitching staff that has the best team ERA and the lowest batting average against in the American League. Seattle first baseman Russell Branyan has hit 20 homers, four short of his career high, set in 2002 in stints with the Cleveland Indians and Cincinnati Reds. Center fielder Franklin Gutierrez is riding an eight-game hitting streak.
