Rodriguez, hit by Cole Hamels and Chad Durbin in Game 3, came up with a runner at third and the Yankees already ahead 1-0 Sunday night. He was hit with the first pitch, stood near the plate with hands on hips and stared at the Yankees dugout.
Umpires met near the mound, plate umpire Mike Everitt signaled the warning and the crowd started chanting, "You used steroids!"
Jorge Posada followed with a sacrifice fly for a 2-0 lead.
The only other player hit three times in one World Series was Pittsburgh's Max Carey in 1925.
