Corey Seager’s Marucci CS5 Maple Bat
Corey Seager swings his big brother Kyle’s bat, a slightly modified 318, and he swings it very well. The Marucci (who recently acquired Victus) is just like his Victus. The handle is a touch thicker than a standard 318 which helps balance it out.
We see Seager swinging Marucci maple, and the closest cut to a 318 is the CU26 at the link.
