According to reports from Joe Doyle of Future Star Series Plus and Daniel Kramer of MLB.com, the Seattle Mariners are calling up their top pitching prospect, RHP Bryce Miller. The righty will make his big league debut as the starter of Tuesday’s game against the Oakland Athletics, slotting into the rotation behind Marco Gonzales and ahead of Logan Gilbert as the M’s rejigger their rotation to handle what is now a season-long loss of LHP Robbie Ray, as well as the disappointing 15-day IL stint at least for RHP Easton McGee after a stellar first start on Saturday.
