"It helps our 'pen," Yost said. "I wanted [Aaron] Crow to have two days off and that allows us to do that. [Jonathan] Broxton was unavailable today. That puts him back on track tomorrow. [Jose] Mijares was limited, [Tommy] Hottovy was limited. That puts them back at full-go tomorrow."
The Twins announced the rainout less than an hour after the scheduled 12:05 p.m. CT start. The rain on a 39-degree afternoon seemed to have settled in for a while.
"We weren't going to start in the rain and they weren't looking for it to clear for three or four hours or so," Yost said. "And they couldn't say it would stop in three or four hours."
The game was rescheduled as the first half of a day-night doubleheader in the middle of the Royals' next visit to Minnesota. On Saturday, June 30, there will be a game at 12:10 p.m. CT and a second game at 6:10 p.m. CT.
"You get an extra player nowadays, you get an extra roster guy on doubleheaders," Yost pointed out.
That provision is part of the latest Collective Bargaining Agreement, so for that day the Royals and the Twins each will be able to add a 26th player to their roster.
"I'm sure it'll be a pitcher," Yost said. "So that'll help."
Saturday's postponement meant that Royals starting pitcher Bruce Chen instead will face the Twins on Sunday. The Twins also pushed starter Jason Marquis back by one day.
The rainout prompted Yost to set his rotation for the next few days. Starting on Monday, Tuesday and Wednesday, respectively, at Detroit will be Jonathan Sanchez, Luke Hochevar and Luis Mendoza. Hochevar's left ankle, which had bothered him somewhat since he was struck by a line drive on Aug. 13, is reported to be fully recovered.
"[Danny] Duffy will move back to the first day against New York, depending on how his side session is tomorrow," Yost said.
Duffy missed his scheduled start on Friday night due to a stiff left elbow and will test it on Sunday. The Royals open a series against the Yankees on Thursday night in Kansas City.
A major plus in the rainout for the Royals is that Broxton, the replacement for the injured Joakim Soria as the closer, will be available on Sunday.
With Broxton coming off saves in back-to-back games, Yost didn't want to use him on a third straight day -- not yet. That's something Broxton hasn't done since undergoing elbow surgery last September.
Broxton pitched a perfect inning to preserve Friday night's 7-6 victory, hitting 97 and 95 mph on the radar gun with two strikeouts.
"He threw the ball extremely well," Yost said. "Everything was good, but he hasn't gone three days in a row and I don't want to push him now. He'll get to where he can go three days in a row."
Thanks to the rainout, he should be ready for action on Sunday.
"This helps our staff, big time," Yost said.
