KANSAS CITY, Mo. – Alberto Castillo's two-run double keyed a six-run sixth inning, and the Kansas City Royals finished a three-game sweep of the Los Angeles Dodgers with a 9-6 victory Thursday night.

On pace three weeks ago to lose more than 110 games, the resurgent Royals now own a neat bit of trivia: They became the first team to pull off three-game sweeps of the Dodgers and New York Yankees in one regular season, according to the Elias Sports Bureau. Of course, interleague play didn't begin until 1997.

The Royals, who were 13-37 when Buddy Bell took over as manager on May 31, swept the Yankees in Bell's first three games. Kansas City is 11-4 under Bell.

Castillo had three RBIs and reliever Mike Wood (3-2) got the victory with two innings in relief of Zack Greinke.

Only one of the six runs in the sixth against Derek Lowe (5-7) was earned. With one out, David DeJesus and Matt Stairs singled, and Emil Brown reached on shortstop Antonio Perez's error as DeJesus scored, making it 3-3.

Terrence Long singled to load the bases, then was forced at second on Shane Costa's fielder's choice grounder that scored Stairs.

As Royals fans roared louder and louder, Mark Teahen hit an RBI single, Castillo hit a two-run double and Ruben Gotay greeted reliever Frankquelis Osoria with an RBI single.

The seven hits in the inning were a season high for the Royals, who got their ninth run in the seventh on Long's RBI double. Every Royals starter had a hit.

The Royals took a 2-0 lead on Stairs' sacrifice fly in the first and Castillo's RBI single in the second, then Olmedo Saenz had an RBI single for the Dodgers in the third.

Jason Phillips singled leading off the fourth and Jason Grabowski hit an 0-1 pitch from Greinke over the fence in right for a 3-2 lead.

Greinke, who was coming off the worst start of his career when he gave up 15 hits and 11 earned runs at Arizona, went five innings and was charged with three runs and eight hits.

Pinch-hitter Jayson Werth hit a two-run double in the ninth for the Dodgers, who left the bases loaded twice. They scored only three runs while losing the first two games of the series.

Notes: According to Elias, the Angels and Seattle Mariners also swept the Yankees and Dodgers in one season since interleague play began, but both were not three-game sweeps. ... The Royals got good news when 1B Mike Sweeney was not put on the disabled list. Sweeney was hurt Wednesday when a runner ran into his outstretched arm. He's day-to-day with a sore left wrist and elbow, but more tests will be done Friday. ... Dodgers third base coach Glenn Hoffman was back in the dugout but not on the field after getting hit in the head by a ball during batting practice Wednesday. Manager Jim Tracy said Hoffman was still "a little cloudy."
