"He's still getting settled into the starting role," Yost said. "After being in the bullpen last year he's still getting lengthened out."
Davis, coming off a win at Tampa Bay in his previous start June 16, has not won consecutive starts since April 10 and 17, his second and third starts of the season.
"Wade gave us seven strong innings and gave up two runs in the fourth," Yost said. "But he pitched really well. He kept us in the game."
NOTES: Of Chicago's first 72 games, 57 (79.2 percent) have been decided by fewer than four runs, including 18 of their last 21. The White Sox also have played 26 one-run games, second most in the American League, and 11 extra-inning games, third most in the majors. Cincinnati and Colorado have played 12 each. ... Despite allowing nine runs, all earned, against Chicago on Friday, Kansas City leads the AL with a 3.49 ERA. In June, while the club has gone 12-7, the Royals' ERA is 2.53 (50 earned runs in 178 innings), second best behind Toronto (2.28). ... Chicago had lost 15 of its last 19 road games and 17 of the last 24 overall, falling a season-high 12 games under .500 before Friday's win at Kansas City. ... One year after having the second-most used bullpen in the majors (behind Colorado), the Royals have the most rested bullpen, having been used for 184 innings (ahead of Philadelphia at 191 2/3 bullpen innings and Detroit at 204). Royals starters have gone at least six innings in 53 games through 72 starts; in 2012 they didn't reach that mark until game No. 118 on August 11.
