Chatwood is coming off three straight quality starts, including two straight in which he has only allowed one run. His 2.69 ERA through 10 starts is the third-lowest in Rockies history behind Mike Hampton in 2001 (2.65) and Ubaldo Jimenez in 2010 (0.88), according to Elias Sports Bureau.
Three things to know about this game
• Reds second baseman Brandon Phillips is day to day with a left ankle injury that forced him to leave Monday's game early and sit out Tuesday's game. He is hitting a career-low .256 this season, but his .420 slugging percentage is his highest since 2012.
• Chatwood has a 0.53 ERA on the road compared to a 5.10 ERA at home. However, his last two home starts have been quality starts against the Giants and Mets, allowing three earned runs over 14 total innings.
• Lamb has run into trouble this season by leaving balls up, making him susceptible to long balls. His 1.9 home runs per nine innings allowed would be the second-highest in baseball behind Milwaukee's Chase Anderson had he qualified for the innings limit.
