There isn't any mystery for the Palmetto State going into the NCAA's Sunday announcement of the 16 host sites for next week's Division I baseball regionals.

South Carolina is a lock to get one for the fifth straight year. But the Gamecocks are on the bad side of the bubble for a top eight national seed.

Clemson has no chance to host a regional. But the Tigers hope to squeeze into the tournament with an at-large invitation.

The NCAA will announce the 16 host sites Sunday night at approximately 9 p.m. on its web site, social media pages (@NCAACWS on Twitter and NCAACWS on Facebook) and ESPN's Bottom Line scroll. The full 64-team field and the eight national seeds will be revealed during an ESPNU hour-long selection show starting Monday at noon.

The Gamecocks were No. 8 in the official weekly NCAA Ratings Percentage Index last Tuesday but slipped to 13 in the updated WarrenNolan.com RPI after stumbling out of the SEC tournament with lopsided losses to Mississippi State (12-0) and Florida (7-2).

Clemson after going 2-1 in the ACC tournament is No. 48 in the WarrenNolan.com RPI.

The top eight national seeds are assured of hosting NCAA tournament super regionals if they advance in first-round regionals. The Gamecocks won a super regional at Coastal Carolina in 2010 on the way to the first of two straight College World Series titles but lost a super regional at North Carolina last year.
