Mookie Betts hit a two-run homer off Danny Duffy in a four-run third inning and the Boston Red Sox defeated the Kansas City Royals 7-5 to complete their first series sweep in nearly a month.
Boston outscored the Royals 23-8 over three games and swept a series for just the fourth time this year, the first since May 10-12 against the Chicago White Sox.
The World Series champions are 27-16 following a 6-13 start. Betts is 7 for 11 with five home runs against Duffy.
