Check swing appeal to U3 during steal attempt to 2nd base. by Tim Kiefer | Mar 29, 2025 | MIBT NFHS Baseball | 0 comments U3 in C position when there is a steal attempt from 1st to 2nd. During the steal, the batter checks his swing and the home plate umpires appeals. Should the home plate umpire appeal? Can U3 see the check swing and the stealing runner?
