Since this game doesn't mean anything anymore do they call it after 9 innings if it's still tied?
As far as I know, it will be played until completion.
The first tie in an All-Star Game occurred on July 31, 1961 at Fenway Park in Boston when the game was called at 1–1 after nine innings due to rain; the only other rain-shortened game was in 1952, but the National League defeated the American League, 3–2 in five innings.
The 2002 All-Star Game, held in Milwaukee, ended in controversy in the 11th inning when both teams ran out of substitute players available to pitch in relief. At that point, Commissioner Bud Selig (a Milwaukee native and former owner of the Brewers) declared that the game would end after 11 innings, and it ended in a 7–7 tie. The crowd booed and threw beer bottles onto the field, and the media were highly critical of this unsatisfactory conclusion.
