David Peterson pitched five scoreless innings with six strikeouts against the Red Sox in the second game of Friday’s doubleheader.
Peterson ends the regular season having allowed three runs over 21 1/3 innings in his final four starts. He’s 6-2 with a 3.70 ERA overall in 15 starts and one relief appearance since being picked up from the Mets. It’s going to be really interesting to see how the Cubs deal with the rotation in the postseason, given that Peterson, Matthew Boyd and Shota Imanaga are all currently performing better than Clay Holmes and Kevin Gausman, both of whom seemed like locks to be among the team’s top three starters a few weeks ago.
