What is an inside out swing?

Answer 1

An inside out swing in Baseball is a swing where the hands come through ahead of the end of the bat which causes the ball to be hit to the opposite field (right field for a right hander or left field for a left hander). Wade Boggs produced many doubles off the "Green Monster" in Fenway by "inside-outing" the ball to left field.

At the point of impact the bat forms a greater than 90 degree angle if one imagines an imaginary line between dead center field which continues through home plate. When a right hander hits a ball to left field or a left handed batter hits the ball to right field the ball is said to be pulled and the bat would usually form an angle of less than 90 degrees at the point of impact.
