When the upstart Arizona Diamondback acquired Jason Marquis, many (myself included) thought it was a good move. The D-Backs acquire an effective pitcher whose ground-balling ways suited their super heater home run park perfectly.

After two substandard starts and one aborted effort, Marquis’ season is over. Marquis is out with a broken leg after taking a line shot off the bat of Angel Pagan in third inning of yesterday’s game.

The crazy thing? He pitched into the fourth, even taking his turn at the plate in the bottom of the inning. Hit the jump for the video.

That’s gotta hurt. Craig at Hardball Talk spitballs that perhaps pitching on the leg further exacerbated the injury. Tough to say, unless Marquis cops to it.

Losing Marquis from the season hurts the DBacks no matter how badly he pitched so far. His open rotation spot falling to the likes of Zach Duke or Micah Owings doesn’t bode well, especially with the Giants beleaguered offense coming to life.
