Narrative:

Just completed landing (cleared for option). Rolling out and preparing for takeoff; gear retracted; propeller struck runway. Aircraft slid 100+ ft and stopped. Gear were partially retracted. Damage to propeller; engine; gear. No other structural damage noted. Not sure; but I might have inadvertently flipped the gear handle up.
