SPORTS ON WEEKEND TV : Golf, Marathon, Basketball

Two local annual events--the Nissan Los Angeles Open and City of Los Angeles Marathon--compete with the long-awaited but now diminished UCLA-Duke college basketball game for sports television viewers on the final weekend before baseball’s return to the airwaves.

* College Basketball: Instead of a chance to prove that it is the best team in the nation, No. 4 UCLA will be seeking to regain its credibility after its Thursday loss to USC when it faces No. 1 Duke at 1 p.m. Sunday on Channels 7, 3, 10 and 42. There is only one telecast today involving a team ranked in the Associated Press Top 25: No. 5 Arizona visits Oregon State at 3 p.m. on Channels 2 and 63. In addition to the UCLA-Duke game, there are three other telecasts Sunday featuring Top 25 teams: No. 24 Connecticut at Seton Hall (9 a.m., Channels 2 and 8); No. 10 North Carolina at Maryland (10 a.m., ESPN) and Illinois at No. 2 Indiana (11 a.m., Channels 2 and 8).

* Professional Basketball: NBC (Channels 4, 36 and 39) presents a Sunday doubleheader: the Portland Trail Blazers against the Chicago Bulls at 10 a.m., followed by the Utah Jazz visiting the Phoenix Suns. The Lakers play host to the Houston Rockets at 7:30 p.m Sunday on Prime Ticket.

* Golf: CBS (Channels 2 and 8) tees off its coverage of the Nissan Los Angeles Open at 1 p.m. today with final round coverage set for the same time Sunday. The Senior Tour’s Chrysler Cup airs at 1 p.m. today on Channels 7, 3 and 42 and noon on KGTV Channel 10, and at 11 a.m. Sunday on all four ABC stations. NBC (Channels 4, 36 and 39) presents the final round of the LPGA’s Kemper Open today at 11:30 a.m.

* Running: KCOP Channel 13 has live coverage of the City of Los Angeles Marathon at 8 a.m. Sunday with a replay at 7 p.m. Super station WWOR will join the coverage in progress at 9 a.m.

* Other Sports: The Kings have a home game against the Montreal Canadiens, which Prime Ticket will air at 7:30 tonight. Azumah Nelson will defend his World Boxing Council super-featherweight title against Jeff Fenech at 7 tonight on Showtime.
