No area collegiate baseball team has won its regular-season conference championship and thereby locked up a bid to the NCAA regionals, scheduled to begin late in May. However, some schools can still qulify by winning playoff tournaments.

Maryland (20-9) played well early, demolishing area competition. But the Terps lost to both regular-season titlist North Carolina and to tournament-winner Clemson last week in the ACC playoffs and its outlook for the regionals looks bleak.

A glimmer of hope remains for American (14-10-1), which concluded its regular season tied for second in the East Coast Conference with St. Joseph's. AU will take on the Hawks today at 3 p.m. for the right to enter the ECC playoffs, which begin Friday at Temple. The tournament winner will receive a berth in the NCAA.

Navy (17-4) has one of the best area records but is in only fourth place in the Eastern Intercollegiate Baseball League, consisting of the eight Ivy League schools, Army and Navy.

With only three league games remaining, the Mids are 7-4 and are longshots to overtake Cornell for first place and an automatic bid. Navy does have a chance to qualify as one of 12 teams selected for the three Eastern Collegiate Athletic Conference section playoffs, whose winners will receive bids.

James Madison (28-9) is currently second in the ECAC-South and is assured of a berth in the four-team, double-elimination conference tournament that it will host starting May 16. The Dukes, who have won four of their last five games and will close their regular season Monday with a doubleheader against Liberty Baptist, will travel to the East regional of the NCAA tourney if they can take the tournament.

Catholic (23-16-1), whose administration is contemplating moving the school from Division I to Division III by the fall of 1981, has finished its regular season and should be one of the four teams involved in the ECAC-South showdown. The Cardinals ended up fourth in the league.

Howard (21-17), which bombed Catholic, 16-3, last week, moved up from Division II to Division I this year and must spend a year on probation before becoming eligible for postseason play.

George Washington (8-15), which lost Coach Mike Toomey in midseason to the Alexandria Dukes, went ot the NCAAs last year but has suffered a disappointing season. The Colonials have been plagued by injuries, inexperience and an inability to play at home on the Ellipse because of pipeline construction. Georgetown (4-14) and George Mason (10-19-1) are also out of the running.
