Jason Day is the WGC-Dell Match Play champion after beating Louis Oosthuizen in Texas. The Australian beat defending champion Rory McIlroy en route to the final and capped a successful week by beating Oosthuizen 5 & 4. Day also regained the World Number 1 spot following a fine run of form that also saw him lift the Arnold Palmer Invitational last week. He takes the title for a second time in three years, and this will be a major confidence boost going into the Masters at the Augusta National.
