After the Nationals beat his Cubs 9-1 Wednesday night, Cubs manager Dale Sveum said the series has been like "men playing against boys." Of course one of the "men" doing most of the damage against Cubs pitching was 19-year-old Bryce Harper, who tripled and reached on an infield hit in his first two at-bats Thursday night after going 4-for-8 with two homers in the first three games. Harper was involved in Thursday's bench-clearing incident when reliever Lendy Castillo appeared to throw at him, causing Harper to yell back at the pitcher as both dugouts and bullpens emptied. "I'd be pretty ticked off if I was getting my teeth kicked in all week too," Harper said.
