The Nationals have not had many losing streaks this year, and Stephen Strasburg, Tuesday's starter, is a primary cause. The Nationals had endured only six losing streaks of at least three games before their current four-game slide. Four of those streaks were ended by Strasburg alone. On May 10, he snapped a three-game streak with a 13-strikeout, one earned run performance against the Pittsburgh Pirates. On May 20, a three-game skid and the Baltimore Orioles met Strasburg and ended with one earned run and eight strikeouts over five innings.
