And still the N.Y. Yankees wheel and deal, now obtaining third baseman Eric Soderholm from the Texas Rangers for players to be named later. Soderholm was AL comeback player of the year 1977 (25 HR, .280 for the White Sox after missing all of 1976 for the Twins with a wrecked knee). Now he can spell Graig Nettles, at 35 four years his senior . . .

Not only did Dave Parker join the all-star tour of Japan, after saying on his Oct. 30 visit to Washington that fluid in the knee would keep him home, but the Pirate pounder hit two home runs in Nagoya yesterday, helping the NL come from 7-0 down to beat the AL, 12-9, and even the tour at 2-2-1. Oriole Ken Singleton homered again for the losers -- a three-run shot off Jim Bibby that would have looked better in Memorial Stadium, World Series Game 7 . . .

Ann Meyers, giving up the $50,000 broadcasting job the NBA Indiana Pacers wished on her after that big-publicity tryout as a player, is due to sign a three-year contract for $130,000 total with the New Jersey Gems of the Women's Professional Basketball League today (it should last so long, let's hope) -- just in time to face the Washington Metros when the Gems open Saturday night in Elizabeth. News conference set in Giants Stadium, a commentary on Gem hopes to move into the 20,000-seat Meadowlands Arena slated to open its doors in December 1980. Gem owner Robert Milo says he aims also to sign Jersey flash Carol Blazejowski and Maryland's Tara Heiss after the Olympics . . .
