Bobby Cox, who guided the Toronto Blue Jays to the best record in the American League and an East Division title, has been named major league manager of the year by The Sporting News. The Associated Press meanwhile gave its version of that award to Whitey Herzog, who took the St. Louis Cardinals to the seventh game of the World Series, where they lost to the Kansas City Royals.

For The Sporting News award, Cox (who recently resigned from the Toronto job to become general manager of the Atlanta Braves) was selected by a vote of his peers, getting seven votes to Herzog's six.

The AP voting was by a nationwide panel of sportswriters and broadcasters. Herzog received 44 votes, Pete Rose 42 . . .

The Royals will meet with President Reagan at the White House Thursday. Peter Roussel, White House deputy press secretary, said the meeting was scheduled for 11:30 a.m. . . .

St. Louis pitcher Joaquin Andujar will miss the first 10 days of the 1986 season under a suspension imposed by Commissioner Peter Ueberroth as a result of his actions against American League umpire Don Denkinger in the seventh game of the World Series. Andujar was also fined $500. The pitcher charged Denkinger in the fifth inning in arguing a called ball, and used abusive language . . .

Billy Williams, one of the National League umpires who worked the World Series, says the Cardinals' final-game petulance was a "disgrace to the World Series." Williams was the first base umpire in the seventh game. He was particularly critical of Andujar. "I saw that (Andujar's rush at Denkinger) and I was ready to kill Andujar," Williams said. "You don't come down off the mound and scream at an umpire. We're not dogs to be hollered at . . . "

The Cardinals managed only a .185 team batting average during their World Series loss to the Royals, but the rest room in the visitors' locker room in Kansas City looks like somebody batted 1.000 in it. "Somebody took a baseball bat to the lavatory and toilet and left it in pieces," said David Owen, an assistant engineer at the stadium. Owen said the Cardinals can expect a bill for between $1,500 and $2,000.
