TORONTO (AP) Mark Buehrle pitched eight sharp innings to become baseball's first 10-game winner, Edwin Encarnacion homered again and the Toronto Blue Jays beat the Kansas City Royals 4-0 Sunday.
Buehrle (10-1) won his sixth straight decision. He gave up six hits, walked one and struck out three.
He lowered his ERA to 2.10, second-best in the AL to New York's Masahiro Tanaka, and improved to 25-12 lifetime against the Royals.
Encarnacion matched Mickey Mantle's AL record with 16 home runs in May, then started off a new month with another drive. He hit a two-run shot off Aaron Crow in the eighth for his 19th homer of the season.
Dioner Navarro also homered as the AL East-leading Blue Jays, who went 21-9 in May, began June with their 17th victory in 21 games.
Jeremy Guthrie (2-5) lost his fifth straight decision, allowing two runs and eight hits in seven innings.
Guthrie has received just one run of support in his past four outings and is winless in 10 starts.
Toronto loaded the bases with two outs against Guthrie in the first but Juan Francisco flied out.
Navarro hit a solo homer in the second with a drive into the right-field bullpen.
Francisco hit a leadoff double in the fourth, Brett Lawrie singled and Anthony Gose had an RBI grounder.
The Royals hit a pair of leadoff doubles against Buehrle, but he never allowed a runner reach third base. Alcides Escobar doubled to begin the third but was caught in a rundown on Nori Aoki's sharp grounder to second.
Eric Hosmer doubled to open the sixth but was thrown out at third by shortstop Jose Reyes on Billy Butler's grounder into the hole.
