The frustration in Bryce Harper had been simmering for some weeks, emerging during the growing pains of his tough second half of the season. A strikeout here resulted in a smashed bat on home plate. Another strikeout there yielded the same result. A double switch in Sunday's game and the rookie, according to Nationals Manager Davey Johnson, was smashing helmets in the runway near the dugout in Philadelphia. When his performance hasn't gone as he has hoped, Harper has worn his emotions openly. In fact, maybe too openly. In Wednesday's 8-4 win in which he notched his first career multiple home run game, Harper spiked his helmet onto the ground trying to beat out a double play in his final at-bat in the ninth inning for his first-ever ejection in the majors.
