While Pete Rose's agent busily bargains with 13 other major league clubs, Tom Seaver has found a home in Cincinnati - through 1983 at least. He signed a new five-year contract yesterday.

The three-time Cy Young award winner for the New York Mets, who had to rally to finish 16-14 for the Reds, this year, found that the club has plenty of bucks as far as he is concerned. And at 33, he is concerned with building his career win total from 219 - "if I can maintain the consistency I have enjoyed the last 12 years and stay healthy, I could reach 300 victories in the five-year period."

Rose, Johnny Bench (six homers in eight games) and Seaver currently are enjoying the Reds' tour of Japan, but Seaver heads home after pitching tomorrow against the Yomiuri Giants.

The Bobby Orr comeback is foundering. Fabulous No. 4 has become so discouraged he is considering retirement as a player, according to omnipresent lawyer Alan Eagleson.

Eagleson said Orr would meet shortly with Chicago Black Hawk brass and they would "try to do a selling job" in convincing the former Boston defenseman he is useful to the club. "Bobby knew, going in, that because of his history of knee problems, 35 to 40 percent (of his ability) was all he could expect, but he wasn't prepared for the reality.

"It's hard for him to accept.He's really down in the dumps . . . I wouldn't be a bit surprised, the way he's talking, if we had a week in which hockey lost two of its great players - first Bobby Hull, then Orr."

By the time Wilf Paiement of the Colorado Rockies returns to the NHL wars it will amount to some comeback, too. For rearranging Detroit wing Dennis Polonich's face with his stick Oct. 25, Paiement yesterday was suspended 15 games by the league. This includes six games already missed, the Rockies' next seven and its two remaining dates with the Red Wings Nov. 29 and Feb. 25.

Comeback? Laurel railbirds warmly welcomed jockey John K. Adams as he returned to competition this week for the first time since he was helicoptered away from Bowie's track on Feb. 2 with brain damage, collasped lung, multiple fractures from a racing spill. Semiconscious three weeks before finding the road to recovery, he wouldn't quit - and got a second-place finish on one of his three mounts his first day back, Monday.

Johnny Holliday not only will emcee the TD club luncheon tomorrow at which Len Hauss receives the Gene Brito award (plates available, $8) but Holliday is gearing up his Radio Oneders basketball team for another benefit campaign - and informing that Mark Moseley, Redskin kicker/Herndon radiocaster. "Will be doing color with me on the WDCA-TV-20 coverage of George Washington basketball." Darn, guess Brian Magid has to play instead this year . . . George Mason U. has a deal with WFEL-AM-1310 to carry all the Patriot basketball games and a pro in tow to call the action: Bob Gotkin, . . . Steeler running back Rocky Bleier will be at TD Club Dec. 4 to tell Monday Morning QB Club some of his exploits . . . The tube rules again: Texas AM&M-Texas football, a Saturday Dec. 2 date, moves to Friday night, Dec. 1 for 9 p.m. ABC-TV beaming. And USC-UCLA makes video, as usual, 4 p.m. EST Saturday, Nov. 18.
