All 30 teams were notified via memo from MLB on the impending enforcement of rules against foreign substances, which goes into effect Monday. As reports of the league nearing such a decision began to surface, Los Angeles Dodgers manager Dave Roberts and Trevor Bauer were outspoken on the subject.
Of course, Bauer had long been waging a war against MLB and their turning an eye to use of banned substances. More recently, Bauer expressed his frustration with the unclear messaging surrounding the topic.
But even with MLB delivering a clear directive on how rules will enforced — and punished — Bauer called into question what would happen if a pitcher is thought to have utilized a sticky substance when in reality only a mixture of perspiration and rosin created that appearance.
