When MLB commissioner Rob Manfred announced that the league would be adopting several new rules, many were wondering how the future of the game might look.Among the swathe of new regulations were restrictions on defensive shifts, larger base sizes and, of course, the controversial pitch clock. All of these new rules were enacted with the goal of promoting offense and shortening games, which lasted over three hours on average last season.Although the MLB stopped short of bringing in an automated strike machine, some fans are starting to think it might be a good idea.During a game on April 10 at Citizens Bank Park, Philadelphia Phillies hitter Nick Castellanos was called out on a borderline pitch and was promptly ejected for drawing a mark on the dirt around home plate with his bat.Talkin’ Baseball@TalkinBaseball_Nick Castellanos gets puts a mark in the dirt and gets ejected after a third strike call he didn't agree with198555Nick Castellanos gets puts a mark in the dirt and gets ejected after a third strike call he didn't agree with https://t.co/3vWLLxnJO6"Nick Castellanos gets puts a mark in the dirt and gets ejected after a third strike call he didn't agree with" - Talkin' BaseballCastellanos, who has yet to hit a home run on the season, now leads the MLB in strikeouts with 17 of them. Despite the frustration he must be feeling, his act of protest was very subtle.MLB fans were not impressed by the actions of home plate umpire John Libka, who tossed Castellanos out without a second thought. The pitch, which was clearly a ball, was framed by Miami Marlins catcher Jacob Stallings to give the illusion of a pitch. The Phillies ended up winning the game handily, but the ejection left a sour taste in the mouths of fans, both online and in-person.Scott Gura@scottgura6@TalkinBaseball_ they are all professionals- whether it’s 14-3 or 4-3 - strike zone SHOULD NOT CHANGE6@TalkinBaseball_ they are all professionals- whether it’s 14-3 or 4-3 - strike zone SHOULD NOT CHANGEJVNIE@jvniemusicEvery single one of these umpires are going to lose their jobs soon.

Although in-game umps continue to be resoundingly popular, Libka and his colleagues are responsible for not abusing the power that has been invested in them.
