It is no secret a lot of runs are being scored in Coors Field this season and that both the Rockies and Red Sox are in the bottom 10 of the majors in ERA from starting pitchers.

German Marquez and Rick Porcello were supposed to start Tuesday with both owning ERAs of 4.75 in 2019. Marquez has had very bad splits at Coors Field, with a 6.23 ERA and opponents are hitting .317 off of him, so him getting scratched Monday afternoon may not hurt the Rockies much.

While Porcello’s 5.49 ERA and 1.6 home runs allowed per nine innings do not elicit confidence, he has had some solid starts recently, giving up three or fewer earned runs in five out of his last six starts, and the Red Sox are 6-3 in his last nine starts.

Recent form is also not in favor of the Rockies in the bullpen, as it entered Monday with the third-worst bullpen ERA in baseball in August while the Red Sox have the best bullpen ERA this month.

The Red Sox have also been a significantly better team on the road than at home, posting a record of 36-28 on the road while being just .500 at home. The Rockies have been the opposite, entering Monday 33-29 at home this season compared to just 25-44 on the road.

The play: Red Sox
