Byrnes was also involved in a 2003 baseball game that included two significant base running gaffes in a single inning. With a chance to close out the Boston Red Sox, the Athletics had a potential rally stifled by two controversial plays. Byrnes was tagged out after failing to touch home plate after a collision with catcher Jason Varitek, who had blocked the plate before attempting to catch the ball. After the collision, a hobbling Byrnes shoved Varitek and began walking back to the dugout. Varitek picked up the ball and tagged Byrnes out. This play was then followed up by Red Sox third baseman Bill Mueller running into Miguel Tejada as Byrnes was rounding third (later in the same inning). Tejada then stopped running home and was eventually tagged out; the umpires called Tejada out because he was tagged as a result of not attempting to advance home, not because of the obstruction by the third baseman.
