Aramis Ramirez and Carlos Pena hit back-to-back homers and the Chicago Cubs beat the Washington Nationals 4-3 Thursday.
Ramirez's two-run shot in the seventh was his 21st of the season, and gave him 16 homers since June 25, the most in the major leagues since then.
Pena followed Ramirez with a clout that curled around the pole in right field and landed on Sheffield Avenue.
Ryan Dempster (10-8) limited Washington to a first-inning home run by Ryan Zimmerman and went seven innings, allowing three hits, walking two and striking out six.
Washington loaded the bases and scored a run in the ninth against Carlos Marmol, but he recovered to get his 26th save.
