Cubs' manager Craig Counsell told reporters on Sunday that David Peterson will be moved to the bullpen with Edward Cabrera rejoining the rotation on Sunday.

A pitcher is allowed to attempt just two pick-offs in a single at-bat, but David Peterson of the Cubs may have forgotten that.

The Chicago Cubs are slowly but surely getting pitching reinforcements to what has already been an excellent staff over the last month.

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.

David Peterson allowed four runs (three earned) in five innings and got the win in the Cubs' 12-6 victory over the Nationals on Wednesday.

David Peterson has been a welcome addition to the Chicago Cubs' rotation. In three of his four starts since he was acquired in a trade from the New York Mets on June 25, the left-hander has held opponents to two runs or fewer.

As Jed Hoyer's front office looks to improve the pitching staff before Monday's trade deadline, an earlier-in-the-summer deal might be paying off, if Peterson keeps pitching like he did Monday in St.

The more starts Peterson has made with the Cubs, the better his sinker has looked and the more groundballs he’s gotten. Wednesday marked his fourth straight start with a ground-ball rate above 50 percent. The start before that run, he was at 47.4 percent.

David Peterson held the Blue Jays to one run in five innings in a no-decision Thursday. Peterson allowed seven hits and walked three, but the one run scored on a balk after Peterson tried a third pickoff of George Springer at first with runners on the corners.
