Action at the Regional will get underway for the fourth-seeded Missouri on Friday at 10 p.m. (CT) as they will play top-seeded Arizona.
Missouri is 0-3 all-time against Arizona, with the last meeting - a 5 to 3 Arizona win - coming back in 2005 at the Fullerton Regional.
That was the first meeting for the two schools since 1976.
Arizona won, 10-1, in the NCAA Regional round in 1976 and the only other meeting came in 1963 when Arizona won, 6-4.
The Tigers have something going for them as they head to the NCAA Regional Round as they are 5-0 in neutral site games this season, including a perfect 4-0 mark last week at the Big 12 Tournament.
