KANSAS CITY, Mo. (AP) – Vin Mazzaro pitched six stellar innings and the Kansas City Royals beat punchless Oakland 2-0 Sunday, handing the Athletics their third shutout in four games. Eric Hosmer homered as the Royals sent the A’s to their 10th loss in 11 games. Mazzaro (2-0), who pitched for the A’s in 2009-10 before being traded to the Royals, allowed four singles, walked three and struck out three. Mazzaro escaped a bases-loaded jam in the first after giving up singles to Collin Cowgill and Josh Reddick and walking Kila Ka’aihue. Brandon Inge grounded out to end the inning. Relievers Kelvin Herrera, Greg Holland and Jonathan Broxton each gave up one hit in one inning, completing the Royals’ fifth shutout of the year. Broxton got his 13th save in 15 opportunities.
