David Kaplan, ABC News White House producer, was listed in stable condition at St. Francis Hospital in Santa Barbara, Calif., yesterday after being struck by a pickup truck Monday night while crossing a street in that California city en route to dinner with friends ...

Kaplan suffered severe facial cuts and a serious knee injury. His wife Sally, also an employee of ABC News here, flew out yesterday to be at his side ...

Kaplan, who is in charge of Sam Donaldson's reports from the White House, is part of the ABC News crew accompanying President and Mrs. Reagan on their brief vacation at their ranch ...

"ABC World News Tonight With Peter Jennings" won the network news race for the first time since early August 1987 with an 11.8 national Nielsen rating and a 20 percent audience share for the week ending Feb. 12 ...

"CBS Evening News With Dan Rather," with an 11.1/19, fell to second for the first time since Nielsen installed its Peoplemeters last September, ending a 20-week stay at The Top ...

"NBC Nightly News With Tom Brokaw" was third for the fifth time in the last seven weeks with a 10.9/19 ...

A spokesman for ABC News yesterday hinted the division wasn't totally surprised by the jump, pointing out that when politics finally gets serious, TV viewers tend to go to ABC, with P.J. and David Brinkley. And last week, after all, included the Iowa caucuses ...

Underscoring that point, last Monday's primetime ABC News special on the Iowa results finished 44th in the national rankings, compared with a 63rd place finish for NBC News' primetime special (CBS News' coverage aired at 11:30 p.m., so it didn't count in the primetime results for the week) ...

The news win announced yesterday prompted ABC News president Roone Arledge, up in Calgary this week riding shotgun on the network's Winter Olympics coverage, to send flagons of champagne to Newsies back in Manchester, N.H., and New York, along with a note expressing his "Warm congratulations!" ...

A spokesman for CBS News said yesterday CBS wasn't "disappointed" by the loss, adding, "We've won 20 of the last 21 weeks." Actually, CBS has won 21 of the last 44 weeks, but who's counting? ...

Aloha, Tom

Their 20th-anniversary reunion special Feb. 3 on the network didn't do all that well in the ratings, but was good enough to earn the Brothers Smothers a six-week run on CBS, starting Wednesday, March 23, at 8 p.m. ...

The one-hour variety shows will follow the same format as their Feb. 3 telecast, which finished in 38th place that week with a 14.6 rating and a 23 percent audience share. Tentative title: "The Smothers Brothers Comedy Hour Specials" ...

They'll air in the "Magnum, P.I.," timeslot into May, when Tom Selleck will return for his special two-hour season- and series-ending finale, which is now in production in Hawaii, Washington, D.C., and Annapolis ...

Which means, "Magnum" fans, that tonight's broadcast of an original episode will be the last one you see until that finale sometime in May (could we have a couple of bars of "Blue Hawaii," please? Thank you) ...

ABC's Winter Olympics coverage Monday night averaged an 18.1 national Nielsen rating between 8 and 11 p.m., compared with a 16.4/24 for NBC and a 13.8/21 for CBS during the same primetime hours ...

Also at ABC News

Reports continue to circulate that another promising female correspondent may be leaving ...

Insiders say that negotiations between Ed Hookstratten, agent for Jane Wallace, and Steve Friedman, executive producer of the "USA Today" magazine show, have been in "limbo" for the past two weeks and that the name of Edie Magnus, co-anchor of ABC's "World News This Morning," is high on Friedman's list of possible replacements ...

Wallace, formerly of CBS' "West 57th," has long been Friedman's choice to anchor the nightly Front Page segment of the syndicated show. But Wallace, who is in no hurry to return to the wars (and could well be a candidate eventually for "60 Minutes"), has apparently not let Hookstratten jump at the first Friedman offers ...

Magnus, whose contract is up in June, is reportedly restless. Our sources hint she's chafing at ABC News' failure to give her a good political assignment this year. In recent months, ABC News lost both Karen Burnes and Kathleen Sullivan to CBS, in part because they too felt management was slow to move them up ...

Friedman has already signed Ken Walker, former ABC News White House correspondent, to be the Money anchor on the program, as well as Robin Young, formerly of "Today," as Life anchor and Bill Macatee, ex-NBC sportscaster, as Sports anchor ...

"USA Today" (with music by John Barry, who composed the music for "Out of Africa") debuts Sept. 12 and is one of the hot properties in the syndicated world right now. Based on the newspaper of the same name, it has already sold in 100 markets (it will be on WUSA here), but still hasn't landed in the key New York and Chicago markets ...

And a tip of the ole rabbit ears (tastefully festooned in blue) to Henry Tenenbaum and Melanie Donahoe, proud parents of Evan Jeremiah, who arrived early Monday at Georgetown University Hospital weighing in at 10 pounds, 7 1/2 ounces. He's their first child ...

Tenenbaum and Donahoe met when she was his boss on "PM Magazine" at Channel 9 here. The former WRC anchor is now doing syndicated movie reviews and entertainment reporting for Post-Newsweek Stations, out of the Washington bureau. She's president of Nova Communications here ...

With a little help from the Olympics and a big boost from the conclusion of "Elvis & Me," ABC jumped into second place last week in the primetime race with a 14.9 rating and a 23 percent audience share ...

NBC as usual was first with a 16.2/25. CBS fell to third, winning only Friday night, with a 14.2/22. ABC took Monday, Tuesday, Wednesday and Sunday ...

NBC got a pleasant surprise when Ben Vereen's arrival on "J.J. Starbuck" moved that series up to 23rd for the week. That network's "The Dirty Dozen: The Fatal Mission" was 33rd, while the premiere of "Sonny Spoon" on NBC could do no better than a 49th-place finish ...

ABC's Saturday night Olympic coverage was 60th with a poor 9.9/17 performance ...

Otherwise, ABC dominated last week's Final And Usually Fatal Five, starting with its Thursday rerun of "Star Trek II: The Wrath of Khan," in 64th, followed, in order, by "The Thorns"; CBS News' "48 Hours" (dealing with the Israeli-Palestinian conflict); ABC's "Sledge Hammer!"; and ABC's "The Charmings," dead last in 68th place for the week ending Feb. 14 ...
