The Cubs recalled Abbott from Triple-A Iowa on Tuesday, Meghan Montemurro of the Chicago Tribune reports.
The righty has pitched 11.1 innings of relief for the Cubs this season, posting a 6.35 ERA with eight strikeouts and seven walks across his five appearances. It's unclear what the intended role is for Abbott, who has been starting in Triple-A but has only worked as a reliever at the big-league level.
