“The Greatest Throw Ever Made At Forbes Field!” And Roberto Clemente didn’t make it! After throwing out his onetime pupil Roberto at the plate last night, tonight Willie burns Willie… Mays vs. Stargell, that is. Giants’ beat writer Bob Stevens reports: “The Bucs scored two in their first at-bats on an error by Tito Fuentes, the rookie shortstop’s first as a major leaguer, a single by Bill Virdon, a double play ball second baseman Hal Lanier fumbled and a double to the centerfield wall by Donn Clendenon. It was here that Mays amazed again. He scooped up the ball at the base of the 406-foot sign, whirled and fired. It came in on one bounce, directly in front of catcher Tom Haller, who put it on the astonished Willie Stargell. It was described by old-timers as the greatest throw ever made in ancient Forbes Field, but it was a costly one. Mays hurt himself on the heroic effort.” Willie leaves the game in the sixth with a pulled groin and his immediate future in doubt. However, Mays will pinch-hit tomorrow and, in two days, will start both ends of the twin bill which concludes the five-game series with Pittsburgh.
