Sandy Koufax and Whitey Ford will pitch July 14 in the "Greatest Baseball Game Never Played"--and maybe July 19 in the flesh, at RFK Stadium.

Yes, if nationwide fan balloting for the Cracker Jack Old Timers Classic here follows the voting for the "never" game, to be played by a computer and broadcast out of St. Louis. Koufax would start for Walt Alston and Ford for Al Lopez, National and American League managers, respectively, who had an audience with capital media yesterday before a White House visit to baseball-minded contemporary Ronald Reagan.

Between them, Alston and Lopez managed 3,462 major league victories and nine pennants. But what have they done lately?

Senor Lopez, 73, retired to his native Tampa--"What do I do? Play golf four times a week." Alston, 70, abides in dear old Darrtown, Ohio; visits top three Dodger farm clubs, once a year each.

Concessions to Father Time when they direct action by living legends: five innings, left field fence just 260 feet out--and only the computer has Gehrig, Ruth et al. But RFK will have the (probable) likes of Aaron, Mantle, Mays, Musial, Williams, Robinson, Rizzuto, Spahn and . . .

P.S. Voting begins Friday for baseball's 53rd All-Star Game, July 13 in Montreal . . .

Now New Jersey's Nets lust after San Diego's first draft pick (No. 1 or 2, depending on Thursday's coin flip with L.A.). Larry Brown, indubitably eager to coach yet another Tar Heel, James Worthy, is quoted as saying, "I still like that pick, and . . . hopefully, we have players or picks or whatever it takes to get it." Except, says Brown, one untouchable: Buck Williams . . .

Prosecution in the Boston College point-shaving case has filed papers in Brooklyn federal court opposing a new trial for James Burke, convicted conspirator--and cited purported threats to Rick Kuhn, former BC player out on bail pending appeal of conviction and 10-year sentence. Kuhn had begun cooperating with investigators . . . Next (sports) case for Dr. Ron Michels and Johns Hopkins' eye institute: detached retina of Joe Delaney, Chiefs' sensational '81 rookie RB. Total repair seen, no interruption of career . . .

Tip O'Neill (reported ill) couldn't be there but that was a capital Capitol sendoff for the 12th annual Lombardi Memorial Golf and Tennis Tournament, June 21--and a first annual tournament eve concert ("Johnny Cash's America," HBO-beamed). This year they go over $1 million raised for the Vincent T. Lombardi Cancer Center at GU.
