The second jewel in the Triple Crown takes over a whole television station today. And tonight, "Dr. Quinn, Medicine Woman," gets herself hitched.
* "Preakness Day" (9 a.m.-6 p.m., WMAR, Channel 2) -- The celebrated horse race itself, from Pimlico Race Course, is not scheduled until around 5:30 p.m., on "ABC's Wide World of Sports" (beginning at 4:30 p.m.). But through the day, Channel 2 offers its own features, interviews and even live coverage of earlier races.
* "Dr. Quinn, Medicine Woman" (8 p.m.-10 p.m., WJZ, Channel 13) -- Take heart. Star Jane Seymour says tonight's long-anticipated wedding between Dr. Mike and Sully (Joe Lando) doesn't mean the romance is over. Tonight's last-minute problems include the fact that intended best man Cloud Dancing (Larry Sellers) has a bounty on his head. CBS.
* "Star Trek: Deep Space Nine" (9 p.m.-10 p.m., WNUV, Channel 54) -- Saloon-keeper Quark (Armin Shimerman) has trouble with his visiting mother -- and not just because the women of his race often do not wear clothes. Andrea Martin ("SCTV") makes a revealing guest appearance as a Ferengi female tired of playing a subservient role in business. UPN.
* "Gramps" (8 p.m.-10 p.m., WBAL, Channel 11) -- One of television's most durable nice-guy portrayers, Andy "Matlock" Griffith, plays a sinister senior citizen. As the title character, he plots to take his grandson away from widower John Ritter. NBC.
* "The Martin Short Show" (11:30 p.m.-1 a.m., WBAL, Channel 11) -- One of the former funny people from "Saturday Night Live" pre-empts the sagging show for a week to try his own quasi-variety show, which went nowhere in prime time. Happily, he's bringing along some others from when "SNL" was full of laughs: Jan Hooks, Harry Shearer and Phil Hartman, plus musician Paul Shaffer, on loan from "Letterman." NBC.
* "8th Annual Kids' Choice Awards" (8 p.m.-9 p.m., Nickelodeon) -- What TV series are in the running for youngsters' favorite, in this show that lets them vote? "The Fresh Prince of Bel Air," "Home Improvement" and "Martin."
* "Indictment: The McMartin Trial" (8 p.m.-10 p.m., HBO) -- Based upon the California child-abuse trial, this new movie sharply suggests prosecutorial zeal had more to do with the case than real evidence of sexual abuse in a day-care center. James Woods plays a defense attorney, Mercedes Ruehl is an unscrupulous prosecutor and Lolita Davidovich is the child expert who suggestively interviews children.
