Taillon (groin) is throwing a bullpen session Saturday, Jordan Bastian of MLB.com reports.
There is no public timetable yet, but Taillon continues to take positive steps forward and seems likely to be ready to return to the Cubs' active roster by the middle of May if he can avoid setbacks. The right-hander has been sidelined for a little under two weeks with a mild-to-moderate left groin strain. Caleb Kilian is filling his rotation spot Saturday at Miami.
