Colorado Rockies game no. 38 thread: Luis Castillo vs. Chi Chi González Share this story The hot-hitting Cincinnati Reds have arrived for their lone 2021 series in Denver, while the Rockies are riding high after a Wednesday night walk-off. Colorado will look to improve their 11-10 record at home as they close out the last four games of an eight-game homestand. Luis Castillo, the Reds’ Opening Day starter, will make his eighth start of the year tonight. He posted an ERA+ of 157 last year, well above Rockies’ 2020 bWAR leader Antonio Senzatela (149). 2021 has turned sour for Castillo, however, as he currently holds career high figures in ERA, xERA, FIP, xFIP and WHIP.
