PITTSBURGH -- Time ran out for Royals starting pitcher Felipe Paulino, who was placed on the 15-day disabled list on Saturday as the club recalled right-hander Nate Adcock from Triple-A Omaha.
Paulino, one of the Royals' brightest lights since he's been in the rotation, had to leave last Wednesday night's game against the Twins with a strained right groin. His immediate future was uncertain until now.
"We wanted to give him a couple days to see if he could get better," manager Ned Yost said. "He wouldn't make his next start, and it would be doubtful if he could make the start after that."
It wasn't Paulino's night against the Twins. The leadoff batter, Ben Revere, smacked him in the right thigh with a line drive. Paulino shook that off, but three batters later, he felt a pull in the same leg while making a pitch to Justin Morneau and had to leave the game.
Yost said that Luis Mendoza, who relieved Paulino that night and went five innings, is the probable starter on Tuesday night against Zack Greinke and the Brewers at Kauffman Stadium. That would have been Paulino's next start.
This is the fourth time this season that Adcock has been summoned from Omaha, where he's gone 3-2 with a 1.99 ERA in five starts. His last appearance for Omaha was Monday, so he's well rested.
"I threw the ball well down there," Adcock said. "In my last outing, I had more walks than I wanted to, especially in key situations, which really hurts. But other than that, my arm feels good and my stuff is good."
Adcock's role with Kansas City?
"Long guy [in the bullpen] right now; we may adjust later," Yost said.
Adcock, in his three previous stays with K.C., pitched in six games (two starts), posting an 0-3 record and a 3.74 ERA.
This is the second time that Paulino has been on the disabled list this season. He had a strained right forearm during Spring Training and didn't make his first start until May 5. Before his injury scuttled his last start, Paulino had held his opponent scoreless in four of six outings. He has a 3-1 record and a 1.67 ERA, best among the team's starters.
The Royals have to keep patching together a rotation. They've also lost lefty Danny Duffy to pending Tommy John surgery, Jonathan Sanchez to left bicep tendinitis and spot starter Everett Teaford to an abdominal strain. Sanchez and Teaford are rehabbing at Omaha.
So, at the moment, Vin Mazzaro, up from Omaha, and Mendoza, who opened the season as Paulino's rotation stand-in, have joined Bruce Chen and Luke Hochevar as starters. Yost won't need a fifth starter until next weekend at St. Louis.
"Depth is the most important thing you can have in starting pitching because you're going to need 'em," Yost said.
Francoeur getting reacquainted with center
PITTSBURGH -- Jeff Francoeur is getting action in center field for the first time since 2006, but the Royals' regular right fielder says he's enjoying the change for Interleague Play.
First baseman Eric Hosmer is in right field so that designated hitter Billy Butler, with no DH in the National League city, can stay in the lineup at first base.
"The one thing here [at PNC Park], is the left-center gap is the big one and I try to favor that. Hoz is in right and he's a good enough athlete to cover that," Francoeur said.
Hosmer, playing his first game in right in Friday night's 4-2 loss to the Pirates, was charged with an error when a base hit kicked away from him.
"He blocked it," Francoeur said. "It just went off to the side. It could've happened to me if I did that."
Royals' camp to feature signed Draft picks
PITTSBURGH -- The Royals' Minor League mini-camp, that will include the signed players from this week's First-Year Player Draft, is beginning this weekend at Surprise, Ariz.
As of Saturday, the Royals had signed half of their 40 selections. The 20th signee was pitcher John Walter, a 6-foot-5 right-hander from Penn State University, who was selected in the 29th round.
Royals, Pirates pay homage with throwbacks
PITTSBURGH -- The Royals and the Pirates honored the Negro Leagues history on Saturday night by wearing replicas of vintage uniforms from that era's teams from their cities.
The Pirates wore uniforms of the Homestead Grays -- not the Pittsburgh Homestead Grays, because they were technically from Homestead, Pa., even though they mostly played in Pittsburgh. The Royals wore those of the Kansas City Monarchs.
The Monarchs operated in 1920-30 and 1937-62 and sent many players to the Major Leagues, including barrier-breaker Jackie Robinson, Satchel Paige, Ernie Banks and Elston Howard.
The Negro Leagues Baseball Museum is located in Kansas City at 18th and Vine.
The Royals announced that left-hander Danny Duffy's Tommy John surgery has been scheduled for Wednesday in Los Angeles. It was delayed to let him get over a case of strep throat.
Vin Mazzaro's RBI single on Saturday night made him the first Royals pitcher to get a hit since Bruce Chen on June 21, 2010, at Washington and the first with an RBI since Brian Bannister on June 12, 2010, at Cincinnati.
The Royals' all-time record against the Pirates is 13-12, including a 7-10 mark in Pittsburgh.
