Chris Sale won his eighth straight decision, Adam Dunn homered in his third straight game and the Chicago White Sox beat the Kansas City Royals 2-1 Sunday.

Sale (11-2) is 8-0 with two no-decisions since a May 12 loss to the Royals.

He allowed one run and scattered a season-high 10 hits eight innings to lower his earned run average to 2.11, which ranks second on the American League. He struck out four and walked none.

Dunn, who leads the league with 28 home runs, drilled a 2-0 pitch from Luis Mendoza (3-6) just inside the right-field pole in the first inning. Dunn has 65 hits overall this season, meaning 43 percent of them have been home runs.

Addison Reed, who blew a save Friday, worked a scoreless ninth for his 14th save in 16 opportunities.

The White Sox loaded the bases with no outs in the second when Alex Rios singled, A.J. Pierzynski was hit by a pitch and Dayan Viciedo stroked an infield single. They converted that into just one run when Rios scored as Alexei Ramirez grounded into a double play. Mendoza threw but seven pitches to five batters that inning.

Mendoza allowed just one hit after the second inning, but took the loss. He gave up two runs on four hits in 7 1/3 innings, while striking out six and walking four.

The Royals avoided a shutout when Mike Moustakas, who led off the fifth with a single and advanced to second on a Sale wild pitch, scored on a Chris Getz single.

Getz moved to third on Alex Gordon's single, but was stranded when Alcides Escobar struck out and Butler grounded out.

The AL Central leading White Sox are 7-2 in their past nine games. The Royals lost for the 10th time in 13 games.
