"[The curve is] huge," Cobb said. "Not only for a put-away pitch."
Cobb had relied a lot on swings and misses with his changeup, hoping that the hitters would chase the pitch outside the strike zone.
"This curveball allows me to start off the count early with a get-me-over curveball, and usually they'll be taking it if it's not the pitch they're looking for," Cobb said. "So being able to get ahead in the count is huge. I wasn't able to do that so much with my changeup. It's more a hoping-they-chase-type pitch, and this is more in the zone."
Cobb noted that the curve he throws now arrives to the plate faster and it has a tighter spin, which keeps it from being identified quickly by the hitters.
