The NCAA men’s basketball tournament, known as March Madness, is nearing its climax with just four teams remaining in the race.

For the second time in the competition’s history, all No.1 seeds have punched their ticket into the Final Four, with Duke, Auburn, Florida, and Houston advancing. Not since 2008 has such an event occurred.

With such a heavyweight finale guaranteed, all eyes now turn to San Antonio’s Alamodome, where on Saturday 5 April, a double header of hoops semi-final action will get underway.

Up first, will be a face-off between Auburn and Florida, while Duke versus Houston will follow. On the line is a place in the national championship game on Monday, 7 April, also in Texas.
