Luffy threw a mast at them, no one was defeated, no one even fought. Shiki FOUGHT Garp and Sengoku, and they defeated him and threw him in Impel Down. To be honest, it might not have taken both of them, but they were both there, and they beat him. I personally think that Garp or Sengoku could have handled him, but a lot more of Marineford would have been destroyed.
