The opening round began Tuesday, March 17. A best-of-three championship series between Oregon State and UTEP resulted in an Oregon State victory on April 3. The 2009 CBI marked the first ever postseason tournament championship for Oregon State as well as a successful conclusion to head coach Craig Robinson's first year. The Beavers were honored with a visit to the White House with president Barack Obama; Robinson is the brother of First Lady Michelle Obama.
