Coors Field doesn't like Edwin Jackson (updated)

As I mentioned earlier, Edwin Jackson hasn't been treated so well at Coors Field over the course of his career. Jackson entered today having allowed 21 earned runs over 12 innings at the Rockies' home park, good for a 15.75 ERA. Those numbers have gotten worse early in today's ballgame. Significantly worse. Jackson received a rude welcome by Rockies hitters, who touched him up for five first-inning runs on six hits. The Nationals' starter didn't truly retire a single one of the first eight batters he faced, although Ryan Zimmerman helped him out by slickly tagging out Carlos Gonzalez when he strayed too far from third base. By the time Jackson had finally retired the side, 10 Rockies hitters had come to the plate, and he'd thrown 36 pitches. Jackson hadn't allowed more than three earned runs in any of his last nine starts. Through one inning today, he's already in a 5-0 hole. Update: Make that 7-0 after two innings. And Jackson has now thrown 59 pitches. Yikes. Update II: Just like that, it's a ballgame again. Coors Field is a special place. The Nats put up five runs in the third inning, making it a 7-5 game. Michael Morse's three-run shot, which barely cleared the center field wall (probably a lazy fly ball to the edge of the warning track in most parks) was the big blow.
