Royals excited for chance to salute military

KANSAS CITY -- The Royals and the Cardinals will join all of Major League Baseball in wearing uniforms with a camouflage motif for their Memorial Day game on Monday, honoring the military and those who have fallen in service to their country.

The Kansas City home uniforms will have the Royals' script and numbers and player names in camo topped by a camo cap.

"First of all, the uniforms look great. It's very cool what we're doing," said Royals second baseman Chris Getz. "And obviously what it represents is even cooler because it's a salute to our soldiers, our veterans who served our country, and it's our opportunity to say thanks by wearing that uniform."

The Memorial Day effort is part of MLB's ongoing recognition of veterans, active military and military families. Since 2008, MLB has committed $23 million to Welcome Back Veterans, an apolitical initiative of MLB Charities and the Robert R. McCormick Foundation.

Armed Forces Day at Kauffman Stadium will include a pregame ceremony and in-game features honoring military personnel. The first 20,000 fans will receive a miniature American flag from the National World War I Museum at Liberty Memorial.

"There's always a good turnout on Memorial Day, and it brings families together and it's more of an opportunity to remember the people who have fallen," Getz said.

Teammate Jeff Francoeur salutes the military.

"There are a couple days in baseball, Memorial Day, July Fourth, that are always important for us because you get to honor the troops, and a lot of baseball players enjoy that. A lot of baseball players have good relationships with different troops, Air Force, Navy, different people," Francoeur said.

"I've got a couple buddies that are in the Navy, a couple that are in the Air Force, so it is always fun honoring our troops. I am a big troop guy."

So is Royals manager Ned Yost.

"To honor them is a great thing to do," Yost said. "I grew up in the Vietnam War era and I just missed going over there by two years. And to see the way that the military was treated after that time and to the time right now that, all of sudden, these guys are heroes. And I mean heroes in the broadest sense. To be able to sit back and honor the job that they're doing is a tremendous privilege for Major League Baseball players."

Butler ejected for second time in career

KANSAS CITY -- Designated hitter Billy Butler became the second Royals player ejected in two days by umpire Marty Foster.

Butler was tossed after objecting to a called strike three in the fifth inning of Sunday's 5-2 loss against the Angels. After discussing the call with Foster, Butler was guided away from the umpire and toward the dugout by third-base coach Eddie Rodriguez. Once on the bench, however, Butler made some remarks that got him thrown out.

"We had a disagreement. I'm not the only one that had disagreements with him this series," Butler said. "He said some things to me I didn't like and it got me fired up."

Second baseman Chris Getz was ejected by Foster in Saturday's 7-0 loss for commentary on a close call at first base in which Getz was called out. Getz also was involved in controversial call by Foster in Friday night's 5-2 loss when Getz thought he'd tagged out the Angels' Mike Trout stealing second base.

This was the second ejection in Butler's career. He was tossed last Sept. 13 at Minnesota for arguing balls and strikes. Foster also ejected Angels manager Mike Scioscia in the ninth inning on Sunday.

Duffy throws three innings in first rehab start

KANSAS CITY -- Royals left-hander Danny Duffy made it through his first Minor League rehabilitation start successfully.

Duffy, coming back from Tommy John surgery, pitched three scoreless innings on Sunday for Double-A Northwest Arkansas at San Antonio. He gave up two hits and two walks along with four strikeouts, a hit batter, a wild pitch and a balk while throwing 63 pitches (37 strikes).

It's expected he could be ready for Major League competition by midseason.

Yost trying to stay even-keeled during Royals' slide

KANSAS CITY -- Royals manager Ned Yost admits it's difficult but he's keeping his cool during the team's recent slide.

"I think you learn that it doesn't do anybody good to vent frustration, which I think we all have, especially after a game like yesterday," Yost said. "It's better to just keep your mouth shut and keep your thoughts to yourself and then get to where you can calm down a little bit and rationally think things through."

Yost was talking to a group of reporters in his office before Sunday's game against the Angels.

"This is the same team that we were having success with two weeks ago," Yost said. "But over the last two weeks or 2 1/2 weeks, we haven't. It's a team that we think can score runs and should score runs. It's just that we haven't. We have to continue to work hard every day to correct that."

It's while that process is going on that Yost has to maintain his composure.

"I've always been a pretty intense guy and, as a player, was always a guy that felt like I could run through the wall. But after you run into that wall 15 or 20 times, you start to understand -- hey, that's not going to happen. You've got to find a better way to do it," Yost said.

"So it's a mindset, something you definitely have to work at. Frustration does nobody any good. It doesn't do me good, it doesn't do them good. [The players] becoming frustrated doesn't do them good. It's something that you really have to fight, day in and day out, and stay within yourself just to do your job. My job is to continue to show confidence and continue to stay patient and continue to work our tails off to get out of this."

Yost had a lengthy visit with club owner David Glass on Sunday, something they occasionally do during the season.

"Mr. Glass has frustrations like all of us. He wants to win as much or more than any of us," Yost said. "The great thing about Mr. Glass is we're all a team, from Mr. Glass to Dayton [Moore, general manager] to myself to the coaches. We're all a team, and we sit from time to time and talk about our frustrations, we talk about our team, we share ideas and it was just a great conversation. I'm glad he came down."

Death of maternal grandmother hits Perez hard

KANSAS CITY -- Catcher Salvador Perez was deeply affected by the passing of his maternal grandmother on Saturday, according to Royals manager Ned Yost.

"Sal was raised by his grandmother and his mother. And it was heartbreaking yesterday to see him as upset and distraught as he was," Yost said. "But he's where he needs to be right now; he's home and taking care of his family and he'll get through this."

Perez flew to Venezuela on Saturday night to join his mother, Yilda, at their home in Valencia. He was placed on baseball's bereavement list for a three-to-seven-day period.

Catcher Adam Moore was called up from Triple-A Omaha to back up George Kottaras while Perez is absent. Moore was selected over Brett Hayes, with whom he's been splitting the catching for the Storm Chasers.

"Adam Moore had a great spring for us, did a nice job, so we picked him," Yost said. "He throws well, blocks the ball good, receives the ball good and has some juice in his bat."
