Sluggball, a 4-on-4 baseball competition co-founded by former Philadelphia Phillies general manager Ruben Amaro Jr., is expected to debut in May and tour minor league stadiums this season. Sluggball focuses entirely on situational hitting, with no fielding or running required. Sluggball teams of six to eight players bring their own pitcher and compete in the 4-on-4 situational challenges using wood bats. Events guarantee two four-round games per team, with championship teams competing for cash prizes. Sluggball’s four directional hitting rounds include pull side, up the middle, opposite field and around the horn.
