I think that maybe the limit on the number of time-outs that can be called will have a serious effect on the guys who think they have to unfasten and refasten their batting gloves after every pitch - even if they didn't swing. After a guy gets called out on strikes a few times because he ignored the fact that the umpire disallowed his request for time, the team Manager is likely to toss that guy's supply of batting gloves in the trash.
