DETROIT— Kendrys Morales hit three home runs and set a franchise record with 15 total bases, and Paulo Orlando homered and doubled as the Royals pounded the Tigers, 10-3, on Sunday at Comerica Park.

With the win, the Royals trimmed their magic number to clinch the American League Central to three. The Royals also increased their lead over the Blue Jays for home-field advantage throughout the postseason to two games.

The Royals had lost 11 of 15 before Sunday.

“I feel good where we’re at,” Royals manager Ned Yost said. “I’ve said it before, but it’s like going through the flu. Nobody wants it but you just get through it. I see signs of us coming out of it. We got 13 games left and now you want to go home and start to get a little momentum for October.”

Morales also tripled and scored five runs. Kris Medlen went five innings and gave up three unearned runs for the victory. Danny Duffy, recently bumped from the rotation, recorded his first career save, pitching the final four innings and striking out six.

“He was fantastic,” Yost said. “That’s as good as I’ve seen Danny throw in a long time. Banging strikes with great stuff. Great job. It’s encouraging because that’s another power arm to add to the bullpen with a bunch of power arms.”

Alfredo Simon took the loss for the Tigers, giving up 13 hits and eight runs in 4 1/3 innings.

“He was up [with his pitches],” Tigers manager Brad Ausmus said. “He was up all day long around the belt. That’s really not what you want at any time when you’re pitching. Sometimes you get away with it with a popup or a fly ball, but the Royals took advantage of it.”
