The Postal Service has held an online pennant race, known as Stamps Batted In, since April to stir interest in the stamps.

So far, Joe DiMaggio is leading with 421,266 votes against 417,066 for Williams, 340,646 for Stargell 332,566 for Doby.

“DiMaggio has dethroned Williams—for now—and there’s just a week left for Larry Doby or Willie Stargell fans to take the pennant,” said Stephen Kearney, director of stamp services. “We’re confident they’ll step up to the plate.”

The competition ends July 19, prior to the July 23 baseball Hall of Fame induction ceremonies in Cooperstown, N.Y. The stamps will be issued Friday.
