Stop me if you've heard this one before: Through three innings, the Nats are being no-hit by a Colorado Rockies pitcher.
This time, it's right-hander Jhoulys Chacin doing the honors. He's retired the first nine Nats hitters in order and we're heading to the fourth inning in a scoreless tie.
Right-hander Jordan Zimmermann is pretty much matching Chacin, save for a two-out, first-inning single by Todd Helton. Through three innings, Zimmermann has five strikeouts and has faced only one over the minimum.
Update: Zimmermann was helped out by three nice fielding plays in the top of the fourth. Third baseman Ryan Zimmerman charged Mark Ellis slow bouncer, made the pickup on the short hop and gunned Ellis out at first. Michael Morse dove to his right to backhand Todd Helton's smash, then threw to Zimmerman, who had to reach back to snag Morse's lob. And shortstop Ian Desmond sprinted to short left-center with his back to the infield to haul in Troy Tulowitzki's pop.
Update II: Zimmerman just lined a soft single to left with two down in the fourth for Washington's first hit.
