Chicago, IL (Sports Network) - Aramis Ramirez drew a bases-loaded walk in the bottom of the 10th inning as the Chicago Cubs edged Washington, 4-3, in the opener of a three-game series at Wrigley Field.
Ramirez barely had time to take the bat off his shoulders before Bruney put four balls out of the strike zone to force in Theriot to end the game.
Carlos Marmol (1-0) picked up the win after hurling a scoreless top of the 10th.
Byrd finished 3-for-5 with an RBI for the Cubs, winners of four straight and five of six. Starter Carlos Silva worked seven innings, allowing seven hits and three runs while also driving in a run with a base on balls.
Starter John Lannan yielded five hits and three runs over his six-inning start, walking five with one strikeout.
Chicago picked up two runs in the second on a Ramirez RBI double, then later in the frame with the bases loaded, Lannan walked Silva to force in a run.
Byrd's single drove in Baker, who tripled to start the third, for a 3-0 game, but the Nats came back with two in the fourth on a bases-loaded walk to Willingham and a sacrifice fly from Kennedy.
Nieves pulled Washington even in the sixth with a two-out base hit to plate Willingham.
The Nats couldn't break the deadlock with two on in the eighth, and the Cubs failed to end the game despite Alfonso Soriano's leadoff walk in the ninth.
