It is tournament weekend in all three divisions across the nation.

Most Division III NCAA regional sites open on Thursday with the SUNY-Cortland (N.Y.) and Tyler-Texas regionals beginning play on Friday. With a 60-team tournament field, six of the eight regional sites feature eight-team double-elimination brackets with play beginning on Thursday. The remaining two sites, Tyler and Cortland, are six-team double-elimination brackets and begin on Friday.

The eight teams that emerge from those regionals will travel to the James I. Moyer complex in Salem, Va., May 20-24, to compete for the NCAA Championship. Defending champion East Texas Baptist opens play in Tyler, Texas, on Friday.

In Division II, all 16 four-team double-elimination regional sites open play on Friday, May 13. Winners of those regional sites will advance to Super Regional sites next weekend, and winners of those best-of-three series will advance to Salem, Va., for an eight-team double-elimination bracket played May 26-30, to determine the NCAA champion. Hawaii Pacific is the defending champion and is hosting a regional site this weekend. The top team in the final NFCA Division II regular season poll, Alabama-Huntsville, plays host to the South 1 regional this weekend.

At the Division I level, the vast majority of automatic qualifying conferences will determine those automatic bids via conference tournaments this weekend. Harvard (Ivy League) and Jackson State (SWAC) have clinched their league’s automatic bids to the 2011 NCAA tournament. Other leagues that do not have a tournament include the Big 12, Big Ten and Pac-10, with all three of those conferences finishing play this weekend. Tournament selection will take place on Sunday evening.
