SURPRISE, Ariz. -- Left-hander John Lamb, after making a good impression in his first Cactus League appearance, has been slotted to start on Saturday against the Brewers.
Lamb will take right-hander Jeremy Guthrie's spot. Guthrie instead will get his work in a simulated game against Royals Minor Leaguers.
"My focus for Jeremy is to get his work in and give Lamb a shot to go over there and pitch two or three innings," manager Ned Yost said.
Lamb, once a top prospect who has been slow coming back from Tommy John surgery, showed good velocity in a two-inning stint against the Cubs on Sunday. He gave up one run on two hits.
Guthrie worked his first two innings on Monday, giving up three runs on four hits. Yost expects him to throw about three innings or 50 pitches in the simulated game.
Gordon slated to miss game with shin bruise
SURPRISE, Ariz. -- Left fielder Alex Gordon was out of the Royals' lineup on Wednesday against the Diamondbacks because of a bruised shin. However, he's expected to play on Thursday against the White Sox.
Gordon took a foul ball off a shin just before lashing an RBI triple in Tuesday's 9-5 victory over the Reds at Surprise Stadium.
"He wanted to play today, but I told him to take the day off and play the next two days," manager Ned Yost said.
Gordon scored a run after the triple and then was taken out of the game to let trainers work on the bruise.
Shields isn't dwelling on contract extension
SCOTTSDALE, Ariz. -- So far there have been no conversations with the Royals about extending James Shields' contract beyond 2014, the pitcher said on Wednesday.
After pitching three scoreless innings in a 6-5 victory over the Diamondbacks, Shields was asked if he'd been negotiating on a contract extension.
"I have not, there have been no conversations between me and the Royals and, to be honest with you, right now I'll let everybody else figure that out," Shields said. "But I'm really focused on getting ready for the season right now and my job is to come out here and win ballgames, and we'll let everything else take care of itself."
Shields has only this year at $13.5 million remaining on the contract he brought with him from the Tampa Bay Rays, when he was traded to the Royals prior to last season. With another good season, there is speculation that as a free agent next winter, he could get a multi-year contract at $100 million or beyond.
"I'm not going to comment on what we're doing or what we're not doing," general manager Dayton Moore said.
"We'll always do our very best to keep as many of our good players here long-term as we can. We're excited about the 2014 season, but it wouldn't be proper for me to comment about any negotiations."
Shields fit right in with the Royals last year as a team leader and pitching staff leader with a 13-9 record, 3.15 ERA, and an American League-leading 34 starts and 228 2/3 innings.
"I've said before, I like it here, I like the city, I like the team, I like where this organization is going," Shields said. "Obviously if they want to do something, then I'm up for listening."
Is Opening Day his personal deadline for talking about an extension? Shields seemed to leave some leeway on that matter.
"As far as talking about it -- with you guys," he said, indicating the reporters. "Spring Training is a decent time to talk about it -- with you guys -- and during the season, I just really want to focus just on my games and winning ballgames for the team. I don't really want to talk about it too much during the season."
Infante makes mark in return as Royals' DH
SCOTTSDALE, Ariz. -- Mike Moustakas stole the show with four RBIs and a home run, but the Royals also got an encouraging return performance from Omar Infante.
Infante, who'd missed five games with shoulder stiffness, returned as the designated hitter in Wednesday's 6-5 win over the Diamondbacks at Salt River Fields. He got to the plate five times, had a double, a single and a walk, and scored twice.
Manager Ned Yost said he hopes to get Infante at second base, paired with shortstop Alcides Escobar, by Friday when the Royals not only play the Giants, but also have a "B" game against the Rangers. Escobar has not yet played in a game after going on paternity leave.
Catcher Ramon Hernandez, who hopes to compete for a backup job, might also see game action for the first time on Friday. He's been out with a sore knee.
Moustakas raised his Cactus League average to .467 with three home runs and 10 RBIs.
"It's Spring Training and it's got to start somewhere, and the work that he's done all winter long is really paying off and it's showing," Yost said. "He had four RBIs today against left-handed pitching. It's just kind of something we expected -- to come back and really have a good year. He's that kind of kid and he's right on track."
Yost gets chance to go over replay procedure
SCOTTSDALE, Ariz. -- There were no managerial challenges Wednesday on umpires' calls during the Royals' first game set up for the expanded instant replay system.
Catcher Salvador Perez squawked briefly after a play at the plate when the Diamondbacks' Mark Trumbo was called safe. Perez had taken a throw from first baseman Eric Hosmer.
"Don [Wakamatsu, bench coach] and I saw it really well. It was kind of inconclusive so if we would have challenged that, we would have lost the challenge," manager Ned Yost said.
However, it wasn't a waste of time.
"It was a great learning experience and I think I learned a good lesson," Yost said. "You don't have to rush right out [to challenge], you can take your time as long as you get out there before the next pitch is thrown."
Yost and his bench were in communication with staffers monitoring the replays in a TV truck, the first of five rehearsals for the regular season.
Yost noted that in the past when he disagreed with a call and wanted to argue, he'd jump up, rush out and confront the umpire.
"There's not a need for that anymore," the skipper said. "You can actually bide your time, buy a little time for the guys in the video room. As long as you can get up before the next pitch is thrown ... and sometimes we might get the information before I even step out to decide if I want to go out."
