Coaches can confidently train rising players with the MacGregor® #73C Senior Little League® Baseballs which are RS-T stamped for use in the regular season and tournament play. The balls pop with the crack of the bat thanks to a cushioned cork core while raised stitching gives pitchers a secure handhold to add spin and power to each throw. Designed to hold up through games and batting practice alike the top-grain leather cover withstands hard impacts and repeated use in every intense inning of the season.
