There are the days Clayton Kershaw pitches for the Dodgers and the course never wobbles. Every other day, any number of lug nuts are loose and the wheels are liable to fall off at the slightest bump in the road.

Dexter Fowler's home run in the Colorado Rockies' first at-bat of the game Monday was the first bump. Wilin Rosario's three-run home run later in the inning was the next.

By the fourth inning, the Dodgers were navigating a bumpy road to nowhere, ultimately losing 12-2 before an announced crowd of 31,570.

"It's a lot easier to throw this (game) out than a 3-2 (game), or (losing) a four-run lead in the eighth inning," manager Don Mattingly said. "Tonight you just got your butt beat."

Starter Ted Lilly left the game after three innings with stiffness in his back, adding to the Dodgers' already long list of injury concerns to their starting rotation.

Lilly will have an MRI exam today to determine the extent of his injury.

The 37-year-old left-hander spent the first 19 games of the season on the disabled list, building up his arm strength after losing most of last season to shoulder problems.

Lilly said his back "was an issue last year, but it went away pretty fast."

The Dodgers were down 4-0 in the third inning when Lilly loaded the bases and was visited on the mound by trainer Sue Falsone with his back worsening.
