CHICAGO (AP) -- Justin Masterson pitched his major league-leading third shutout of the season and the Cleveland Indians completed their first four-game sweep in Chicago since 1948, beating the White Sox 4-0 Sunday.
Masterson (10-6) gave up six hits, struck out eight and walked one. He blanked the White Sox for the second time this year.
Masterson faced the minimum 18 batters through six innings thanks to two double plays and a pickoff.
After Masterson began the ninth with two strikeouts, he allowed a single to Alejandro De Aza and hit Alexei Ramirez with a pitch. Masterson struck out Alex Rios looking to end the game.
The win moved Cleveland into a virtual tie with Detroit atop the AL Central.
