After working a perfect first and escaping a two-on, one-out jam in the second, things went south.
The right-hander offered his only walk of the afternoon followed by a pair of doubles -- one by Cesar Hernandez and the other by Ryan Howard. Then, ahead 0-2 on Maikel Franco, Strasburg left a fastball up and Franco clocked his second home run of the year over the center-field wall.
That ended the damage in the third, but it picked right up again in the fourth. Nat-killer Odubel Herrera doubled, Cole Hamels singled to right and Bryce Harper's throw to the plate -- Herrera had held at third -- missed everybody and skipped to the backstop.
