KANSAS CITY, Mo. — On a day in which the Kansas City Royals were trying to officially advance to their first World Series in 29 years, Game 3 starter Jeremy Guthrie was apologizing to his former club. The former Orioles pitcher issued an apology for wearing a post-game shirt stating, “These O’s Ain’t Royal,” adding that he made no connection with the play on words from the song “Loyal” by Chris Brown. Countless fans and members of the organization took exception to what was perceived as a sign of disrespect for a club that helped Guthrie revitalize his career when he arrived in Baltimore in 2007. “Unfortunately for me, I used a lack of judgment in putting that shirt on after the game,” Guthrie said Wednesday afternoon. “Never changed, came in here, and wore it. What ensued was not what I intended. There was no intention to call the attention to the other team, friends, and former teammates, certainly not the organization and most definitely not their fans.” Guthrie allowed one earned run and three hits over five innings in Game 3 as the Royals won 2-1 to take a 3-0 lead in the American League Championship Series.
