Colorado Rockies right-hander Tyler Chatwood is proving unbeatable on the road. Chatwood pitched eight strong innings, Trevor Story and Gerardo Parra homered and the Rockies held the Los Angeles Dodgers to one hit in a 6-1 victory on Monday night. ''It wasn't my best outing, I didn't have good command early but after the second inning, I settled in,'' Chatwood said.
