gaps between the infielders. Infield shift Some extreme repositioning known as a shift has been used against pull hitters, a strategy that has become more prevalent in Major League Baseball since the late-2000s. For example, versus excellent left-handed pull-hitters like Ted Williams, David Ortiz, Joey Gallo and Ryan Howard, teams will move more players to the right side of the field. They sometimes play with the shortstop behind or even to the right of second base. The second baseman may simply move to the right, in which case this just qualifies as a shift, or he might move deeper into shallow right field. Another variation has the third baseman move to where the shortstop would play in the shift, leaving the shortstop (who is generally the team's best infielder) to cover the left side of the infield. Many believe that this shift was first employed against Ted Williams in the 1940s, as thought up by then-Indians manager Lou Boudreau. However, it was first used against Cy Williams in the 1920s.
