CHICAGO -- James Shields scattered eight hits over seven shutout innings to lead the Kansas City Royals to a 5-1 victory over the Chicago White Sox on Friday night.
Shields (5-7) struck out two and walked a pair in the opener of a three-game weekend series at U.S. Cellular Field.
Kansas City got an early run on David Lough's solo home run to open the third inning. The Royals doubled the lead in the seventh when Miguel Tejada's one-out sacrifice fly drove home Salvador Perez from third.
Chicago had its most serious threat with the bases loaded and two out in the sixth for catcher Josh Phegley. But the Royals got out of the inning as Phegley grounded to third on a fielder's choice.
White Sox starter Jose Quintana (5-3) worked an efficient seven innings, allowing two earned runs on six hits. He threw 106 pitches, walked just one and struck out five.
Right-hander Kelvin Herrera relieved Shields and gave up an eighth inning solo home run to Conor Gillaspie that briefly trimmed the Royals lead in half.
But Kansas City added two ninth inning runs off Chicago reliever Matt Lindstrom.
The first came on Lorenzo Cain's single to center that scored Jarrod Dyson with no outs. Lindstrom departed after allowing a single to Mike Moustakas to right that drove home Perez.
Left-handed reliever David Purcey was on the mound as the Royals scored on an error by White Sox left fielder Casper Wells. He misplayed a line drive on rookie outfielder David Lough's one-out sacrifice and brought Cain home.
Lough's lead-off homer gave the Royals a 1-0 lead in the third. He lined a 2-2 pitch an estimated 388 feet to right field.
The White Sox had Paul Konerko in scoring position with two out in the fourth, but Gordon Beckham flew to deep center to end the inning.
The teams were heading in opposite directions as they hit the 100-game mark for the season on Friday.
The White Sox, last in the AL Central, snapped a three-game losing streak with Thursday's 7-4 victory in the finale of a four-game series with Detroit. The Royals, seven games behind the division-leading Tigers, had won three in-a-row and were coming off a sweep of the Orioles.
