Argument with ump results in Sveum's ejection

WASHINGTON -- Cubs manager Dale Sveum was ejected in the bottom of the fifth inning of Wednesday's game against the Nationals at Nationals Park.

Trailing, 5-0, Cubs starter Chris Volstad had a 1-0 count on the Nationals' Michael Morse when home-plate empire Larry Vanover ejected Sveum from the dugout.

Sveum then ran onto the field and argued face-to-face with Vanover before first-base umpire Jerry Lane, the crew chief, joined in.

"I just didn't appreciate him eyeballing our dugout for absolutely no reason at all," Sveum said. "I just don't think that's right when you're looking in our dugout for no apparent reason at all."
