On July 2, 2011, Márquez ejected both Toronto Blue Jays manager John Farrell and Jon Rauch.
After a single from Philadelphia Phillies 2B Chase Utley scored on a single from CF Shane Victorino.
However, it appeared that Rauch was angered previous to the play, relating to Márquez"s strike zone, as it was fairly apparent that Utley did appear to be safe. This ejection gained notoriety because of the size of Rauch and his anger towards Márquez. Rauch, being 6"11" and weighing well over 250 pounds, had to be restrained by catcher Justice of the Peace Arencibia, Farrell, and third base coach Brian Butterfield.
In the process, Rauch"s jersey was ripped off and Farrell"s jaw was dislocated by Rauch.
