KANSAS CITY -- Left-hander Noel Arguelles, signed by the Royals for nearly $7 million last winter, has been shut down because of a sore shoulder.
Arguelles, a Cuban defector, has been in Surprise, Ariz., since he reported for Spring Training and has not yet pitched for a team in the organization.
"But he's seen two different doctors and everybody thinks he's going to be fine," general manager Dayton Moore said Friday.
The Royals had Arguelles cut back during Spring Training because he'd thrown extensively for months as he auditioned for Major League clubs. Now the question is will he be ready to pitch in the Minor Leagues before the season is over?
"We expect him to, but we'll see how that plays out," he said.
Moore said another top left-handed prospect, Mike Montgomery, has had some tricep tightness in his throwing arm but that it's not believed to be serious.
Montgomery, who last pitched on May 27, has a 3-1 record and a 2.84 ERA in five starts for Northwest Arkansas.
Texeira takes hill for KC vs. Tigers
KANSAS CITY -- It didn't take the Royals long to get newly-acquired right-hander Kanekoa Texeira into the bullpen flow.
With the Royals leading the Tigers, 7-3, on Friday night, Texeira was summoned to pitch the ninth inning, and he did so nicely after an unseemly beginning. Pinch-hitter Don Kelly hit a drive to left field that Scott Podsednik let roll out of his glove for an error.
"That's part of the game," Texeira said. "I didn't think he dropped the ball until I saw the runner on second base."
Unfazed, Texeira retired Austin Jackson, Johnny Damon and Magglio Ordonez in order on ground balls to end the game. Just in case, closer Joakim Soria was warming up in the bullpen.
"If two guys got on, we had Jack [Soria] ready for the save, but he did a nice job," manager Ned Yost said.
Texeira was claimed on waivers Thursday from the Seattle Mariners. He was in 16 games for the Mariners with one loss and a 5.30 ERA.
"Four-run game and I felt good out there. I just wanted to throw strikes and stay ahead of the count instead of picking the corners like I was doing before," Texeira said.
Normally Yost plans to use him earlier in the game.
"He's not an overpowering guy, a sinker-slider type with a decent changeup," Yost said.
General manager Dayton Moore feels that Texeira's talents fill a need in a bullpen that includes hard-throwing right-handers Kyle Farnsworth, Robinson Tejeda and Blake Wood.
"Texeira fits as a sinkerballer," Moore said. "He blends in well with the group that we have. When you put bullpens together, that's what you try to do -- get a combination of all their pitches because you can't get nine hitters in the lineup out the same way."
Brad Thompson was also a sinkerballer but he struggled and was designated for assignment when Texeira was claimed.
Betancourt leaves with upset stomach Friday
KANSAS CITY -- Royals shortstop Yuniesky Betancourt left Friday night's game after seven innings because of an upset stomach and light-headedness.
"He ate something either last night or this morning that made him sick. He was throwing up this morning and he came to the park and his stomach was upset so he really didn't eat much," manager Ned Yost said.
"He got a little light-headed in the eighth inning with the heat and humidity so we got him out of there, loaded him up on fluids and he feels much better and should be ready to go tomorrow."
Yost said Betancourt's condition was not believed to be related to a mild concussion he suffered in a game against the Rangers on May 25.
Moustakas, Hosmer to stay in Minors
KANSAS CITY -- If you were expecting third baseman Mike Moustakas to materialize in the Royals' Major League lineup this season, don't count on it.
General manager Dayton Moore spiked that speculation on Friday when discussing the success this season of Moustakas at Double-A Northwest Arkansas and first baseman Eric Hosmer at Class A Wilmington.
They might move up a notch in the Minor League system, but there are no plans to get them to Kansas City in 2010.
"We're just going to let it play out and we'll assess it a month from now," Moore said. "They are not candidates to be on our Major League club at any time this year. That's an advance decision that we've made."
Moore also indicated there's no rush to bring Alex Gordon back to the Majors from Triple-A Omaha, where he's learning to play left and right field. Gordon is batting .361 with nine homers, 25 RBIs, but is still working on altering some aspects of his swing.
"The numbers are very good, the approach is not where we want it yet for long-term success," Moore said.
Royals pleased with Yost
KANSAS CITY -- Royals manager Ned Yost gets a positive rating so far from general manager Dayton Moore.
"I think he's done a terrific job," Moore said. "He's very focused and he intends on getting where this organization needs to be. ... He's very direct in the way he does things -- I like it."
Moore recalled that he was impressed with Yost from the time he was hired as a special advisor last winter.
"We had just come off a very disappointing year where the expectations were high. You're always looking for people to join your organization and bring energy and morale in perspective and Ned is able to do that," he said.
Moore added that Yost's six years as Milwaukee manager and his background as a catcher were proving valuable in his handling of the pitching staff.
"It's very clear that he has a great feel for the pitching aspect of it, which is the most important part of it," Moore said.
Aviles dropped in lineup
KANSAS CITY -- Second baseman Mike Aviles has been dropped in the lineup, batting seventh against the Tigers on Friday night. He had been swinging out of the second spot.
"I think at times putting Mike in the 2-spot takes away from his aggressiveness, some of his ability to drive in runs," manager Ned Yost said. "When he's swinging good, he hits the ball to all fields and we were asking him to be a little more patient in the 2-hole."
He put catcher Jason Kendall in the second spot where he'd batted four times previously. Kendall responded with a perfect night, 3-for-3 with a walk and three RBIs in a 7-3 victory.
"Kendall's a perfect No. 2 hitter. He's a guy that likes to take pitches and is a good situational-type hitter so we thought we'd try that for a while," Yost said.
Aviles, in a 0-for-12 skid, had not started two of the previous three games. He was 1-for-4 with a run scored against the Tigers.
