Alec Marsh unveiled a new slider this week, writes Anne Rogers.
“It was literally as simple as just changing the grips around,” Marsh said. “And I threw one in the bullpen, and we were like, ‘OK, well, that’s a big difference.’ And then, I just stuck with it.”
Because of the new movement, Statcast had a hard time registering which pitches were sliders and which were curveballs against the Red Sox. But generally, Marsh’s slider is around 84-86 mph, while his curveball typically doesn’t get above 83 mph.
