Double switch is something used in National League because no DH rule. Replace a pitcher and position player at same time so pitcher bats 9th coming up.

OBR 6.10 "The Designated Hitter may be used defensively, continuing to bat in the same position in the batting order, but the pitcher must then bat in the place of the substituted defensive player, unless more than one substitution is made, and the manager then must designate their spots in the batting order."
