Pearson is slated to serve as the Cubs' opening pitcher for Monday's game against the Phillies, Andy Martinez of Marquee Sports Network reports.
Pearson will be making his major-league start since 2021, when he was a member of the Blue Jays. He made the full-time conversion to the bullpen in 2022 and hasn't covered more than two innings in any appearance since being acquired by the Cubs in late July, so Pearson likely won't cover more than the opening frame or two before giving way to the bullpen. Hayden Wesneski, who was activated from the 15-day injured list Friday, is a candidate to be used in bulk relief once Pearson is done for the day.
