The Cleveland Barons cannot meet their National Hockey League payrolls, yet the Cleveland Nets have $1.5 million for Bjorn Borg in the three-year World Team Tennis contract he is expected to sign today . . . Black Hawk Bobby Orr, for one, and the St. Louis blues, for another, are in almost as much danger as the Barons of prematurely ending their life in the NHL . . . Fran Tarkenton's knee may not be as ravaged as Orr's but i's bad enough - and his other pursuits sweet enough - that he is talking retirement from pro football . . .

But before we get into that, our valentine couple of 1975 - Johnny Bench and Vickie Chesser Bench - must be breaking Cupid's heart as Valentine's 1977 nears.

Mrs. Bench and the World Series hero of the Cincinnati Reds were in domestic relations court this week for a preliminary divorce hearing, and Vickie, quoted by the Cincinnati Enquirer in a copyrighted story, relates that the baseball star "broke my heart and spirit."

It did't take long after their huge, celebrity-studded wedding Feb. 21, 1975, Mrs. B. said, that things started snowballing downhill toward their breakup a year later and her husbands's petition last August for a divorce on grounds of gross neglect: "After the wedding party, he took his best man home with us - and they played Ping-Pong . . .

Tennis: It's all set, or Net, for Borg and his entourage - finance Mariana Simionescu and coach Lennert Bergelin - to sign with the Cleveland WTT entry in ceremonies at a midtown New York restaurant today. Nets owner Joe Zingale was flying in to do the honors, with a package including $15,000-20,-000 each for Simionescu as a player and Bergelin to take over as the team's coach; sorry, Marty Rieseen player-coach for two years . . . . And sorry, Pennysylvania Keystones. That WTT franchise has died aborning - overturn by the Soviets. WTT commissioner Earl (Butch) Buchloz disclosed that the U.S.S.R. national team entering the league is supplanting the Keystones to play a full 44-match schedule over the 13-week season, beginning in April.
