The teams

No. 1 seed UL-Lafayette

Overall record: 53-7

Conference record: 26-4 Sun Belt, first

RPI: 5

The scoop: The Ragin’ Cajuns have the nation’s best record and are the country’s only team with 50 or more wins. UL-Lafayette carries the nation’s longest winning streak (10 games) into its 14th regional but only its second as host. The Cajuns won the Sun Belt regular-season title by a record seven games and swept four games to take the tournament crown.

No. 2 seed Mississippi State

Overall record: 37-22

Conference record: 18-12 Southeastern, tied for fourth

RPI: 32

The scoop: The Bulldogs had their most successful SEC campaign since 1997 and are in the NCAA tournament for a 34th time. MSU advanced to the College World Series championship round last year before falling to UCLA 2-0 in the best-of-three final. If the Bulldogs win this regional, they could face Ole Miss in the super regional round.

No. 3 seed San Diego State

Overall record: 42-19

Conference record: 17-13 Mountain West, third

RPI: 41

The scoop: The Aztecs beat host UNLV 4-3 in Sunday’s MWC tournament finale to win the title for the second straight year. The Aztecs’ 42 wins are their most since 2009. Their head coach — major league Hall of Famer Tony Gwynn — took a leave of absence in April as he battles mouth cancer.

No. 4 seed Jackson State

Overall record: 31-23

Conference record: 9-15 SWAC, eighth

RPI: 271

The scoop: The Tigers went 0-2 in the Baton Rouge regional last year, including a 15-1 elimination-game loss to the Ragin’ Cajuns. JSU swept four games against teams with better league records to win the SWAC tournament, upsetting regular-season champ Alabama State 9-8 in the May 18 title game in New Orleans.
