Report: MLB's enhanced plans for enforcement of foreign-substance rules being finalized

Major League Baseball is cracking down on pitchers' use of foreign substances. 

The league's enhanced plans for the enforcement of foreign-substance rules are being finalized, and a memo could be sent to teams as soon as the week ahead, according to ESPN's Buster Olney. 

Olney notes that several rules are being discussed:

• Umpires will randomly check pitchers for foreign substances during games. 
• Offenders could be suspended 10 days without pay. 
• Position players will also be subject to foreign-substance checks.

Pitchers using foreign substances and baseball's lack of discipline regarding the issue have become hot topics around MLB with averages and runs down across the board. The league's .236 batting average currently ranks lowest in history. 

Los Angeles Dodgers pitcher Trevor Bauer was recently investigated for doctoring baseballs, and St. Louis Cardinals reliever Giovanny Gallegos had his hat taken away from an umpire who suspected he was cheating.

Cincinnati Reds outfielder Nick Castellanos recently slammed MLB for not cracking down on the issue, saying, "The league doesn't care."

According to ESPN, one source said during a game in recent weeks it was very obvious a pitcher was using a foreign substance, and players began "screaming at him to stop cheating."
