MLB will institute new protocols this season to crack down on the use of foreign substances on baseballs, according to a memo obtained by ESPN.
The memo sent to all 30 MLB teams includes information about inspecting balls taken out of play, analyzing spin rate data and closely monitoring dugouts and clubhouses.
The new procedures aim to limit the use of foreign substances, such as pine tar, that can increase spin rate, effectively leading to more strikes.
The league will examine whether a pitcher's spin rate significantly improves from his "normal" spin rate. According to ESPN, MLB will also test balls taken out of play, both randomly and if officials have reason to suspect wrongdoing.
