KANSAS CITY, Mo. -- Kelvin Herrera and Wade Davis both gave up runs for the first time in nearly three months as the Kansas City Royals' dominant bullpen was touched up Tuesday night in a 7-5 loss to the Chicago White Sox.
Davis replaced Herrera with two on in the seventh inning and walked Jose Abreu to load the bases for Conor Gillaspie, who cleared them with a triple to right-center on a 2-2 pitch to give Chicago a 7-5 lead.
That ended Herrera's scoreless streak at 30 2-3 innings, dating to June 24. Also snapped was Davis' shutout streak of 31 2-3 innings, a club record for a reliever, with the first run charged to him since June 25.
The rare bullpen failure prevented Kansas City from gaining ground on AL Central leader Detroit, which lost at Minnesota. The Royals remained 1 1/2 games behind the Tigers, but still lead Seattle for the second wild-card spot.
Kansas City used nine pitchers, a club record for a nine-inning game, in a contest that lasted 4 hours, 16 minutes - the longest nine-inning game in Royals history.
Nori Aoki had his second straight four-hit game, including a sixth-inning single that put the Royals up 5-4, but this time the bullpen couldn't hold it.
Adam Eaton had four hits, matching his career high, and scored two runs for Chicago.
Royals manager Ned Yost went to his bullpen early when starter Liam Hendriks was pulled after three-plus innings. He gave up four runs on seven hits and a walk.
In his past three outings, Hendriks has allowed 11 runs and 18 hits in 9 1-3 innings.
White Sox rookie right-hander Chris Bassitt also failed to make it out of the fourth. He threw 94 pitches in 3 2-3 innings, allowing three runs on six hits and four walks.
White Sox: DH-1B Paul Konerko, who has not played since breaking his left hand on Sept. 2, took extended batting practice. "When he's fit to play he'll get some time," manager Robin Ventura said. "I don't necessarily want him going out there not having swung a bat in two weeks. He'll get an at-bat here or there to acclimate him."
Royals: LHP Danny Duffy, who skipped two starts because of a sore shoulder, threw a four-inning simulated game. "There's nothing wrong," Duffy said. "I felt stronger than I did for about the past month." He is slated to start Monday in Cleveland.
White Sox: LHP Chris Sale, an AL Cy Young Award contender, starts the series finale. He has trouble with Royals DH Billy Butler, who has a .359 career average against him with three home runs, two doubles and 10 RBIs in 39 at-bats.
Royals: RHP Yordano Ventura has nine made consecutive quality starts, a club record for rookies.
