The Western Hockey League champion Medicine Hat Tigers and Ontario Hockey League champion London Knights meet in the Memorial Cup Final on Sunday as they battle for supremacy at the top of the Canadian Hockey League.

So far, London has held its opponents to three power-play goals in 15 chances while the Knights are 2-for-8 on their opportunities. Last year in the final, Saginaw had three power plays with one of them for five minutes, and London had none.
