Four Atlantic Coast Conference schools were among the 16 selected as regional hosts for the 2009 NCAA baseball tournament, the NCAA announced.
Fourth-ranked North Carolina joined conference members Clemson, Florida State and Georgia Tech as ACC hosts.
Other conferences with multiple host schools are the Big 12 (Oklahoma, Texas); Big West (Cal State Fullerton, UC Irvine); Conference USA (East Carolina, Rice); and SEC (Florida, LSU, Ole Miss).
Top-ranked UC Irvine has been selected to host a college baseball regional for the first time in school history.
The Anteaters, a College World Series participant two years ago, joined Louisville and TCU on Sunday as first-time hosts. Each of the 16 host schools are guaranteed berths in the 64-team tournament, which starts Friday.
Of the 64 spots, 30 are awarded as automatic berths to Division I conference tournament winners; 34 are at-large selections.
The complete pairings for the 2009 field will be announced during Monday's The Road to Omaha selection show (ESPN, 12:30 p.m. ET).
Each regional features four teams playing in a double-elimination format.
The road to Omaha begins with regional play at the following sites/hosts:

The eight super regional hosts will be announced at 11 p.m. ET on June 1.
