Correia's effort not enough in 6-1 loss to KC
Minnesota starter Kevin Correia was dominant through seven innings.
But the Twins bullpen struggled in the eighth and lost control of the game.
Burton leads the Twins with 22 holds this season, but entered the game having allowed five earned runs in six innings against the Royals.
After allowing three hits and four runs in one-third of an inning, Burton's ERA against the Royals this season had jumped to 12.79, and his record against them fell to 0-3.
''Kansas City as a whole's got our number,'' Twins pitching coach Rick Anderson said when asked about Burton's struggles against the Royals.
''I don't even know what our record against them is, I just know it's not real good. We just haven't played very well against them.''
Shields - the key part in the deal that sent top prospect Wil Myers to Tampa Bay in the offseason - struck out seven and notched his American-League best 22nd quality start.
He only allowed one hit through seven innings before running into trouble and leaving in the eighth inning.
Correia matched Shields for the most part. He also struck out seven batters to tie his season high and seemed to get stronger after working out of jams in the fourth and fifth innings.
''I didn't feel like I had a real good strikeout pitch the first couple innings, but then I got better control of my curveball and then I had a pretty good changeup tonight,'' Correia said.
''I was able to kind of hit my spots and get them looking for one pitch, and got a few looking strikeouts.''
After 118 pitches, Anderson said Correia was ''zapped,'' and manager Ron Gardenhire decided to send Burton out to start the eighth.
Seven consecutive Royals hitters reached base in the eighth to break open the scoreless game.
Gordon followed with a bases-clearing double down the right-field line that made it 5-0 and sent most of the fans at a steamy Target Field heading for the exits.
''Good ballgame until we got into the eighth, and then things kind of unraveled there, we couldn't really stop them,'' Gardenhire said. ''The ball kept going their way, bunts, you name it, everything, stolen bases, bloops, and there you have it, a five spot.''
Billy Butler hit his 14th home run in the ninth.
