Richard is 7-13 with a 4.78 ERA in 29 starts. In his past four starts, though, he has an ERA of 4.38. In his last start, he faced the Cardinals and he tossed six shutout innings. He also only allowed five hits and one walk.
However, this match-up leans to the Rockies as, in Coors Field, he is 1-4 with a 9.21 ERA and a .378 opponent batting average (neither of which are typos) in eight starts.
In his one start in Coors this year on July 19, he went 3 2/3 innings allowing 14 hits and 11 runs (10 earned). The Rockies ended up winning 18-4.
Tyler Chatwood has been excellent in the month or so. Since August 9, he has made eight appearances (two starts). He has gone 17 2/3 innings in that span and he has allowed just three runs (1.53 ERA) and a .258 opponent batting average.
With the Padres, Lyles has a 5.79 ERA in two starts. On the season, he is 1-2 with a 6.75 ERA. The Rockies got rid of him because of that. In Coors this year, he has an ERA of 6.00 in 27 innings with a .290 opponent batting average.
Tyler Anderson will be making his return to the starting rotation as he replaces Kyle Freeland, who has been awful. From the article discussing what the Rockies postseason rotation looked like, I had this to say about Freeland and his stats.
"In Freeland’s last three starts and 10 1/3 innings pitched, he has an ERA of 6.97 with nine walks, a .366 opponent batting average, a .471 on-base percentage, and a .488 slugging percentage. Since his return from the disabled list on August 15, they haven’t been much better: six starts, 28 innings, 0-3 record, 5.46 ERA, 17 walks, .317 average against, .403 on-base percentage, and a .481 slugging percentage."
Anderson has only made one appearance since his return from the DL. On Monday, he went four innings only giving up one hit, zero walks, and he struck out four.
