if the lefty hitter has the speed to beat out a close play ;) A lefty hitter that pulls the ball to the right side 47% of the time (using fangraphs since it has the wider net that certainly includes 2nd base territory) and hits those balls as grounders 60%+ of the time is giving those ground balls to the easier side of the infield to turn (the reasoning being that a second baseman covering is always going away from the throw, whereas the shortstop covering, who also generally has the better arm, is moving towards it.)
