Most switch-hitters have been right-handed throwers, but there have been several notable switch-hitters who threw left-handed, including Cool Papa Bell, Lance Berkman, Dave Collins, Doug Dascenzo, Mitch Webster, Wes Parker, Melky Cabrera, Nick Swisher, Justin Smoak, David Segui, Daniel Nava, and J. T. Snow (who, in the final years of his career, hit exclusively left-handed). As of the 2018 season, there were 48 active switch-hitters on MLB rosters. Five of the league's 30 teams did not have a switch hitter on their roster in 2018.
