Gregory Santos, one of the Mariners’ hardest-throwing relievers, is finally on track to rejoin the bullpen after months sidelined by a knee injury. With the bullpen stretched thin all season by injuries and heavy workloads, his return could be a game-changer. Santos, who can hit triple digits with his fastball, had to pause his rehab for personal reasons but is now ramping up in Arizona. If all goes well, he could be back by mid-September. How much of a difference do you think Santos will make down the stretch for Seattle? #Sports #Baseball #Mariners
