Jimenez perfect through three, Rockies grab lead on Helton solo homer (updated)

Colorado Rockies right-hander Ubaldo Jimenez already has one no-hitter to his credit. Can he do it again?

Jimenez has breezed through the Nationals’ lineup, retiring the first nine hitters in order. He’s got three strikeouts, four ground balls and only Danny Espinosa and Jesus Flores have gotten a ball to the outfield, flying out in the first and third innings, respectively.

On April 17, 2010, Jimenez threw the first no-hitter in Rockies history, a gem against the Braves.

Nationals right-hander Jason Marquis just allowed a solo homer into the right-field stands by Todd Helton to lead off the fourth. It’s Helton’s 10th of the season, good for a 1-0 Colorado lead.

Update: Marquis escaped the fourth down only 1-0 despite loading the bases with two down on a single by Troy Tulowitzki and two-out walks to Ian Stewart and Chris Iannetta. The righty got Jimenez to bounce to third, where Ryan Zimmerman charged a slow roller and made a nice three-quarters throw to first.
