Ryan Zimmerman hit three home runs in the first five innings, leaving the Baltimore Orioles with a four-run deficit to overcome against one of the best pitchers in the National League. On a toasty night at Camden Yards, the Orioles turned to their hottest player to get them out of the hole. Chris Davis went 4-for-4 with two homers, and the Orioles battled back to beat Jordan Zimmermann and the Washington Nationals 9-6 on Wednesday night.
