Justin Verlander (hamstring) is scheduled to throw a bullpen session on Sunday.

It’s not hyperbolic to suggest that this bullpen session, in addition to an upcoming minor league rehab start, will go a long way towards determining whether Verlander makes one last start for Detroit before officially hanging up his spikes at the end of the season. The 43-year-old future Hall of Fame starter has been on the shelf with hip and hamstring issues since early April.
