BALTIMORE (AP) After watching starter Erick Fedde dominate the Baltimore Orioles for six innings, the last thing Washington Nationals manager Dave Martinez wanted to do was turn to his ineffective bullpen to finish the game.

Unfortunately, Martinez had no choice. And, not surprisingly, a one-run lead turned into a rare lopsided loss for the hottest team in the big leagues.

Trey Mancini hit two home runs , and Baltimore pummeled four Washington relievers in a 9-2 victory Wednesday night that provided the Orioles with a split of the two-game interleague series.
