Stephen Strasburg was at his dominant best in the early going Saturday, retiring 13 of the first 14 Chicago Cubs he faced, seven via strikeout. And then it all fell apart for the Washington Nationals' right-hander after a teammate's error. The No. 1 overall draft pick in 2009 and NL All-Star in 2012 wound up dropping his fifth consecutive decision of 2013, slumping his shoulders and bowing his head while laboring through a 42-pitch fifth inning during an 8-2 loss to the Cubs.
