"That's just men playing against boys right now," Sveum said following the Nationals 9-1 victory over the Cubs on Wednesday.
The Cubs haven't been able to hang with the Nationals all series, which is a reflection of the season for both teams. The Nationals currently have the best record in baseball at 84-52, while the Cubs have the second-worse record in the majors at 51-85.
Wednesday's game was the second straight in which the Nationals hit six home runs against the Cubs after topping Chicago, 11-5, on Tuesday night. Sveum was ejected during Wednesday's game, screaming at umpire Larry Vanover in the bottom of the fifth inning. The Cubs look to get their first win in the series on Thursday night after dropping the last three against the Nationals.
