Part of Saturday's pitching plan
Cubs manager Craig Counsell said Wednesday that Peterson will "be involved" in the pitching plan for Saturday's game in Seattle, Meghan Montemurro of the Chicago Tribune reports.
Analysis
With Edward Cabrera (finger) landing back on the 15-day injured list after just one start with the big club, a spot in the Chicago rotation has reopened. Peterson ended up losing his spot in the rotation when Cabrera returned this past weekend, but the former looks poised to slot back in either as a traditional starter or bulk reliever Saturday. The southpaw has logged a 4.06 ERA and 32:17 K:BB over 44.1 innings covering eight starts and one relief appearance for the Cubs.

Shifting to bullpen role
The Cubs announced that Peterson will be moved to the bullpen after Edward Cabrera (hamstring) was reinstated from the 15-day injured list Sunday, Patrick Mooney of The Athletic reports.
Analysis
Rather than shifting to a six-man rotation, manager Craig Counsell will send Peterson to the bullpen to provide the club with a multi-inning arm to replace Javier Assad, who was optioned to Triple-A Iowa on Sunday. After a disastrous run with the Mets to begin the season, Peterson had pitched more credibly since being acquired by the Cubs in late June. Over eight starts with Chicago, Peterson has gone 4-1 with a 4.19 ERA, 1.37 WHIP and 31:16 K:BB across 43 innings.
