Posterior generated visual for St. Louis Cardinals: Quinn Mathews Returned to Triple-A Memphis After Cardinals Doubleheader

The St. Louis Cardinals announced that left-hander Quinn Mathews has been returned to Triple-A Memphis after serving as the 27th player for yesterday's doubleheader in Cincinnati.

The 27th-man designation is a standard procedural move for doubleheaders — clubs are permitted to carry an extra arm for the twin bill, with the understanding that the player heads back down once the second game ends. Mathews had been slotted to start Game 1 of that Cincinnati series, per a Cardinals rotation note from earlier in the week, so his brief stay on the active roster was always going to be exactly that.

With Mathews back in Memphis, the Cardinals' roster returns to its standard configuration. What remains unconfirmed is any timetable for a potential next call-up or how the rotation lines up going forward.
