ESPN.com's Graham Hays previews the super-regionals.
Each super-regional series will be played over two days (a single game on Day 1, with a double-header on Day 2 if a decisive third game is needed). As detailed here, two series will be played on Thursday-Friday (Florida-Georgia, Oklahoma-Louisiana Lafayette); three will be played on Friday-Saturday (Alabama-Washington, James Madison-LSU, Florida State-Utah); and three on Saturday-Sunday (Michigan-Missouri, Auburn-Arizona, Oregon-UCLA).
For many of these teams, making the super-regionals is old-hat. The super-regional format is now in its twelfth year, having been introduced in 2005. Here are the teams with the longest continuous streaks of making the supers:
Alabama, made it all twelve years
Oklahoma, seven straight
Oregon, seven straight
Louisiana-Lafayette, five straight
Florida State, four straight
UCLA, three straight
LSU, two straight
Auburn, two straight
And some impressive near-continuous streaks:
Michigan, eleven out of twelve
Arizona, eleven out of twelve
Florida, nine of the last ten years
Missouri, eight of the last nine years
Georgia, eight of the last nine years
Washington, seven of the last eight years
Finally, James Madison and Utah will be making their first-ever appearances in the super-regionals.
