Lou Brock visited President Carter in the Oval Office yesterday, beating Carl Yastrzemski to the honor just as he beat Yaz to 3,000 hits. And nobody could draw any bile out of Brock over those tales the Red Sox star had been invited ahead of him; the great Cardinal was completely class.

Carter and Brock beamed as the ballplayer gave the chief executive a Louisville Slugger, Brock's wife and their two youngsters standing by.

"The only bad thing about this meeting," Carter said, to laughter, "was that, well, Ty Cobb was from Georgia" . . .

Steve Brooks, winning jockey in the 1949 Kentucky Derby, has died, just a few weeks since another Derby captor, Conn McGreary, passed on.

The fall occurred at Arlington Park in suburban Chicago, where he was an exercise rider. Brooks had 10 mounts in Kentucky Derbies, and won it aboard Ponder . . .

Herman Franks said, aw, he never told anybody in the media he was getting out as manager of the Chicago Cubs at season's end because he was "fed up" with today's breed of players -- but, heck, since the cat's out of the bag, he got out yesterday, a week ahead of schedule.
