Wade Davis will start Saturday for the Royals, as they try to bounce back from Friday's 9-1 drubbing from the visiting White Sox.
In three June starts, Davis has allowed just four earned runs over 17 2/3 innings.
He has transitioned into the Royals starting rotation after spending all of the 2012 season in relief with the Rays.
He said he's been more consistent lately with his stamina, after he'd tire early in games during the season's first few weeks.
"I'm getting stronger later in the game now rather than weaker. Kind of reversed," Davis said. "Usually what I used to do is be building up and when I got to 89 pitches, I was going strong and would stay there. But early on this year, it was hit or miss. I'm getting more consistent."
And Saturday's weather forecast has low-to-mid-90s temperatures, so he said he should be nice and limber by first pitch.
"It shouldn't take too long to get loose for a Saturday day game," he said. "I think I pitched here only once in the summertime. It didn't take too long to get warmed up."
Jose Quintana will start opposite Davis, and he'll hope the White Sox can score runs in bunches, as they did Friday.
In his second year in the Majors, Quintana has received an average of 3.86 runs per game of run support. That's the second-lowest total on the starting staff, ahead of only Chris Sale, who's received an AL-low 2.77 runs per contest.
Although the left-hander hasn't factored in a decision in June, the White Sox are 1-4 in his past five starts.
The game they won was his most recent start, in which he lasted only 4 2/3 innings but Chicago went on to win, 4-2.
White Sox: Omogrosso joins the bullpen
Right-hander Brian Omogrosso is back with the White Sox, after he was recalled Friday from Triple-A Charlotte.
The reliever has taken the place of Deunte Heath, who was optioned to Charlotte after Thursday's loss to the Twins.
In early June, Omogrosso was sent down to Triple-A after 11 appearances with the White Sox in which he went 0-1 with a 5.14 ERA.
"I understood the situation when it happened," Omogrosso said. "I'm the guy who has the option left. I just went down there to work hard and try to get back here. You just persevere."
Royals: Paulino's stiff back has him in Kansas City
Pitcher Felipe Paulino sounds confident that a strain in his lower back won't set him back as he recovers from Tommy John surgery.
Paulino, who had the ligament replacement surgery last July, was scratched from a game with Double-A Arkansas.
"Nothing's wrong with me. I'm OK, just here to check it out," Paulino said. "It's nothing bad. They know it's nothing major, just a strain in the lower back. It's no big deal."
He said he believes he'll be back in Minor League games this week, but for now he's in Kansas City with the big league club, and he could throw a bullpen or a simulated game before returning to his rehab assignment.
• Paul Konerko is 5-for-16 in his career off Davis, and Dewayne Wise is 5-for-12. All other White Sox hitters are a combined 9-for-68 (.132) off the right-hander.

• In three career starts at Kauffman Stadium, Quintana has given up 10 earned runs over 17 innings, and he has not factored in a decision.
• The White Sox lead the all-time series between the two teams, 352-317.
