Michael William Muchlinski (/mʊˈlɪnskiː/; born February 26, 1977) is an American Major League Baseballumpire. He umpired his first Major League game on April 24, 2006, and was officially hired by MLB prior to the 2014 season.[1][2]
Muchlinski was the home plate umpire on June 20, 2015, when Washington Nationals pitcher Max Scherzer pitched a no-hitter against the Pittsburgh Pirates.[5] Scherzer had a perfect game with two outs in the ninth inning and a 2–2 count on José Tábata. Tábata appeared to lean into Scherzer's eighth pitch of the at bat, controversially ruled a hit by pitch by Muchlinski.[6]
