CHICAGO -- The Chicago Cubs walked Washington star Bryce Harper a record-tying six times, then beat the Nationals 4-3 when Javier Baez homered in the 13th inning Sunday for a four-game sweep.
The Cubs won their seventh in a row and improved the best record in the majors to 24-6. Washington lost its fourth straight.
Harper matched the major league record for walks in a game, last done by Jeff Bagwell in 1999, and walked 13 times in the series. Harper was hit by a pitch the other time he came to the plate.
The Elias Sports Bureau said Harper was the first player in history to reach base seven times without an official at-bat.
Baez homered with one out off Blake Treinen (2-1). Travis Wood (1-0) was the last of four Cubs relievers who combined for eight scoreless innings (see full recap).
