Mazzaro was traded along with minor league pitcher Justin Marks to the Kansas City Royals for David DeJesus on November 10, 2010. After starting the 2011 season with the Omaha Storm Chasers, he was recalled by the Royals to replace the injured Bruce Chen on May 10.
He surrendered 14 runs in 2⅓ innings in an emergency appearance out of the bullpen in a 19–1 loss to the Cleveland Indians at Kauffman Stadium on May 16, 2011. Besides setting a new franchise record for most runs yielded in a game, he became the first pitcher in the modern era (since 1900) to allow that many without pitching 3 innings. His 14 earned runs given up was also the most by a relief pitcher since Les McCrabb of the Philadelphia Athletics allowed the same amount in four innings in a 19–4 defeat to the Boston Red Sox on April 16, 1942. Originally scheduled to be the starter the following night, Mazzaro was optioned back to the Storm Chasers after the game. Mazzaro was called back to Kansas City on June 7 after Royals starting pitcher Sean O'Sullivan was placed on the disabled list. He finished the season with an overall record of 4-3 with a 5.73 in 18 games, primarily in relief. On November 20, 2012 the Royals designated Mazzaro for assignment as they cleared room on the 40-man roster ahead of the Rule 5 draft.
On November 28, 2012, Mazzaro was traded to the Pittsburgh Pirates with first baseman Clint Robinson in exchange for right-handed pitcher Luis Santos and left-hander Luis Rico. Santos and Rico both pitched in the Dominican Summer League in 2012.
