NEW YORK -- Mike Moustakas gave the Kansas City Royals a lead they never relinquished Sunday with a fourth-inning solo homer and the Royals took advantage of sloppy play by the New York Mets to score three runs in the fifth inning of their 6-2 win in front of 25,658 at Citi Field.
The Royals (56-52) took the final two games of the series and have won 11 of their last 12. The Mets (49-60) have lost four of their last five.
Moustakas and Eric Hosmer each had two hits and an RBI for the Royals. Every member of Kansas City's starting lineup had a hit except catcher George Kottaras, who struck out, drew three walks (two intentional) and was hit by a pitch in five plate appearances.
Lorenzo Cain had a two-run single in the fifth, and Hosmer and Alex Gordon had RBI singles in the sixth.
Ervin Santana (8-6) picked up the win for the Royals after allowing one run, five hits and three walks while striking out five in six innings.
The Mets scored their lone run against Santana in the fifth when they loaded the bases with two outs before Santana struck out Marlon Byrd to escape the jam.
Byrd also helped the Royals out in the fifth when he lost two fly balls in the sun as Kansas City expanded its lead to 4-0.
David Lough led off the inning with a seemingly routine fly to Byrd, but he couldn't find it and the ball landed next to him for a double. Lough went to third on a sacrifice by Miguel Tejada before pinch-runner Jarrod Dyson raced home on a wild pitch by Zack Wheeler (4-2). Lough was lifted because of right quad tightness.
After a walk to Hosmer, Gordon hit a long fly to left. Byrd settled under it and momentarily caught it, but he dropped the ball on the warning track for a two-base error.
Cain then hit his two-run single to shallow right field.
But the Royals barely avoided their own blooper reel moment. Gordon ran on contact, but Hosmer hesitated to see if the ball would be caught. Gordon came within inches of passing Hosmer, and the two crossed home plate literally one after the other.
The Royals added two insurance runs in the sixth when the first four batters of the inning reached against Gonzalez Germen.
Eric Young was 2-for-4 with an RBI single for the Mets and John Buck had an RBI single in the eighth when the Mets stranded two runners against Louis Coleman.
Wheeler allowed four runs (three earned) on five hits and a career-high tying five walks while striking out five in five innings.
NOTES: The Royals made series of transactions before the game. All-Star C Salvador Perez was placed on the seven-day concussion disabled list and replaced by C Brett Hayes, who was recalled from Triple-A Omaha. Perez took a foul tip off the facemask in the 12th inning on Saturday and spent the night undergoing tests at a hospital. ... RHP Wade Davis was placed on the Family Medical Emergency List. He will be out a minimum of three days and a maximum of seven days. The Royals recalled LHP Will Smith from Triple-A Omaha in a corresponding move. ... Mets closer Bobby Parnell remained unavailable because of a stiff neck. ... The Mets are off Monday -- the first of their four off-days of the second half -- before opening a series with the Colorado Rockies at Citi Field on Tuesday.
