MLB will once again be on the lookout for pitchers using illegal substances. A memo was sent out to all 30 teams on Thursday detailing how umpires will go about cracking down on "sticky stuff."Umpires' inspection of pitchers' hands and gloves will be more detailed and frequent. The inspections can be random, and the umpire may check anything, including fingers, belts, hats, etc.Jayson Stark@jaysonstBREAKING: According to sources, MLB sent a memorandum to all 30 teams today, announcing ways it will step up efforts to stop the use of "sticky stuff" by pitchers this season.Details in @TheAthleticMLBtheathletic.com/4316886/2023/0…12445BREAKING: According to sources, MLB sent a memorandum to all 30 teams today, announcing ways it will step up efforts to stop the use of "sticky stuff" by pitchers this season.Details in @TheAthleticMLBtheathletic.com/4316886/2023/0…One thing that is new this year is that the checks can be random. Last season, starting pitchers were checked after innings, while relief pitchers, especially closers, were often checked before innings. This year, checks can come before or after innings for any pitcher.Umpires have been given more control with these checks this season. If an umpire observes suspicious behavior from a pitcher, they can go and do an inspection in the middle of the inning."Again?

Having umpires check pitchers is something that the league can easily avoid.MLB's crackdown on "sticky stuff" is a problem it createdSeattle Mariners vs. Minnesota TwinsBaseballs, for the most part, aren't very tacky. You can even see this at the high school level. Before a high school game, you'll see the pitchers or the coach rubbing the baseball up to give them more of a grip.Japan's Nippon Professional Baseball League adopted a baseball back in 2011 that came pre-tacked. They don't have to rub the ball up before the game. This has been something MLB fans have been asking for since the league implemented mid-inning checks.Umpires slowing down the game to check and see if Justin Verlander, Shohei Ohtani or Clayton Kershaw are using illegal substances can easily be avoided. Perhaps the league will come up with an alternative option in the future.
