From Kyle Seager to Corey Seager to Joe Panik, this slightly modified S318 profile is a touch thicker than a standard 318. Panik swings a Maple bat, and the most similar cut that Marucci offers is the CU26, available at the link for $150.
Panik previously swung the Louisville Slugger T141, an ultra-balanced bat with a swing weight score of 1 out of 5, “most balanced” by Slugger. The S318, according to Slugger.com is more end loaded, with a swing weight score of 4 out of 5, “slightly end loaded.” It has a thick handle and a medium barrel.
