SURPRISE, Ariz. -- Catcher Manny Pina was being examined by the Royals' medical staff after injuring his right knee during Wednesday's workout.
Manager Ned Yost said that Pina was catching when he caught his spikes and "tweaked" the knee. The extent of the injury wasn't immediately known.
Pina is competing with Brayan Pena for a backup job behind regular catcher Salvador Perez.
Royals agree to terms with Holland, Coleman
SURPRISE, Ariz. -- The Royals agreed to contract terms with two relief pitchers, right-handers Greg Holland and Louis Coleman, the club announced on Wednesday.
Holland, who posted a 5-1 record, four saves and a 1.80 ERA in 46 games last season, was signed to a one-year deal at $497,150.
Coleman, who was 1-4 with a 2.87 ERA and one save in 48 games last season, will receive $491,750 for the 2012 season.
Still unsigned are five players with less than three years of service -- shortstop Alcides Escobar, second baseman Johnny Giavotella, catcher Salvador Perez and pitchers Danny Duffy and Vin Mazzaro.
Orlando sidelined by sports hernia
SURPRISE, Ariz. -- Paulo Orlando, an outfielder invited to the Royals' Major League camp for the first time as a non-roster player, sat quietly at his locker on Wednesday morning and pondered his fate.
Orlando has a sports hernia and was scheduled to travel to Philadelphia for an examination and evaluation. Surgery is a possibility.
Manager Ned Yost said Orlando had the hernia for about three weeks. Last season, Orlando hit .305 in 45 games with Double-A Northwest Arkansas and .235 in 58 games for Triple-A Omaha. He's trying to become the first Brazilian-born player to reach the Majors.
"I might miss Spring Training, but I'll be ready for the season," he said.
Yost to use six-man rotation in Cactus games
SURPRISE, Ariz. -- For at least a while during Cactus League games, Royals manager Ned Yost will use a six-man rotation for his starting pitchers rather than the usual five.
"We're going to go with a six-man rotation in Spring Training because we've got 15 guys we're trying to get lengthened for starting positions, and that's including some of the young guys we have," Yost said.
"Actually the Texas Rangers did this last year and talking to [Rangers pitching coach] Mike Maddux, I really like the concept behind it. With the regular five-man rotation we're trying to piggyback guys to begin with, which is fine until you get to the four-inning mark. Then you run out of innings for your relievers."
Part of the plan will be to continue having the pitchers throw in live batting practice sessions. A starter can pitch in a game, take two days off, throw in batting practice, take two days off and pitch in another game.
Yost sees an advantage to throwing in batting practice over merely throwing a side session with no hitters.
"It's in a non-competition situation, so if you want to work on your changeup or your slider, you can work on your pitches and see how hitters adjust to it, see how hitters are swinging on it, then take it two days later and throw it in a game," Yost said.
This system will be in place only for the first three or so weeks of games or until starting pitchers start throwing four innings (or the equivalent numbers of pitches) in each outing. (Some pitchers also will get work in "B" games or Minor League games.)
"We have to get better. We have to lower our walks. We have to consistently pitch down in the zone better, if we're going to have any chance to compete," Yost said.
The plan will mean that hitters will be brought over from the Minor League side of the complex for the BP sessions.
"We'll have to get Minor League hitters," Yost said. "The big league hitters won't dig it."
