KANSAS CITY -- Royals reliever Robinson Tejeda is day-to-day after injuring his left calf muscle during pregame warmups Friday night at Kauffman Stadium.

Tejeda's injury -- though enough to make him unavailable for games Friday and Saturday night -- would most likely not place him on the disabled list, Royals manager Ned Yost said Saturday.

According to Yost, Tejeda was feeling better and more mobile Saturday.

"He strained his calf yesterday, so we're just kind of taking it day-to-day," Yost said. "I don't think it's going to be a DL issue. So we'll just wait."

After a rough start to the season, Tejeda has become a valuable contributor to the Royals' bullpen. Tejeda is 2-2 with a 5.57 ERA in 17 appearances this season. The righty picked up his second win of the season May 1 against the Tampa Bay Rays, when he tossed three perfect innings. Through 21 innings pitched, Tejeda has registered 18 strikeouts.

Guillen's hand OK after plunking

KANSAS CITY -- Jose Guillen took a shot to his right hand in the first inning of the Royals' 5-4 loss to the White Sox on Saturday night, as a Jake Peavy fastball was a little too high and tight.

Guillen threw down his bat and paced back and forth in pain before trainers assessed the damage. Guillen did not leave the game; however, the ball left a pretty heavy bruise on three of his fingers.

"He's fine," Royals manager Ned Yost said. "He got hit on the finger and it got real numb for awhile. It took like an inning, but he finally started to get feeling back."

After he was hit, Guillen looked down at his fingers and saw them changing colors.

"He got me pretty good," Guillen said. "I knew something was wrong when I looked down at my fingers and they started turning blue."

Guillen finished the game 0-for-2 with a walk, two strikeouts and a run scored.

Yost effusive in praise of Kendall

KANSAS CITY -- Royals manager Ned Yost knows exactly what he wants his prototypical baseball player to be like: Jason Kendall.

"For me, Jason Kendall is the epitome of what I want in a player," Yost said. "He is hard-nosed, hard-playing, focused and prepared every single day. When he steps on that field, he gives you everything he has. So when that game is over, you know he didn't save anything."

This season, Kendall has started in 35 of 37 games behind the plate for the Royals, leaving backup catcher Brayan Pena with little playing time.

Yost has managed Kendall before, and knows exactly how to tell him when it's time for a day off.

"It's hard to keep him out of ballgames," Yost said. "He's a guy that shows up every day ready to play. What I'll generally do is, I'll pick out a day every two weeks or so, and I'll tell him three or four days ahead of time so he can start mentally preparing himself because he's going to be mad, because he loves to play."

Even with Kendall's passion for the game, Yost still understands that he needs to make time for Pena to keep him in top shape.

"[Kendall] also understands that if something happened [to him], we need to make sure that Pena is ready," Yost said. "You can't just totally forget about him. You have to find ways to get him at-bats and get him in ballgames, too."

Armed Forces Night at The K

KANSAS CITY -- In an effort to honor those men and women who defend America so bravely, the Royals deemed Saturday night Armed Forces Night at Kauffman Stadium.

Sitting in the Buck O'Neil Legacy Seat was Army Private First Class James Cerv, who came home to Overland Park, Kan., on leave from Afghanistan on Mother's Day. Cerv, along with the 101st Air Assault Division out of Fort Campbell, Ky., will return to Afghanistan in a few weeks.

Cerv's grandfather, Bob, served in World War II and also played for the Kansas City Athletics. Bob Cerv still holds Kansas City's Major League record for home runs with 38.

Opening ceremonies, though disrupted by rain, consisted of a video tribute to all the men and women in the Armed Forces, as well as a flag the size of the entire outfield being spread across the field for the national anthem, held by men and women of the Armed Forces.

One of the many members of the Armed Forces in attendance was Joseph Hunter, a Private in the Army. Hunter has one year of military service under his belt and is stationed in Fort Riley, Kan.

Hunter is excited to be apart of his first Armed Forces Night.

"It's pretty cool," Hunter said. "It's good to know that people still support us, because there are a lot of people out there who don't. It's good to know that they are still doing a lot of stuff out here for us." Hunter and his platoon will deploy to Iraq in early fall of 2010.
