KC@ARI: Moustakas' line drive scores Infante

MILWAUKEE -- Royals second baseman Omar Infante had no apparent elbow problems during a Minor League game on Thursday in Surprise, Ariz.

Infante, recovering from inflammation caused by a spur in his right elbow, had five plate appearances as the designated hitter.

"He just played catch, he didn't play in the field. I didn't get anything that indicated there was a problem," said Royals assistant general manager J.J. Picollo.

Infante walked and went 0-for-4, with two popups to shortstop, a strikeout and a hard-hit grounder to second base.

"He took his swings and I didn't see any hesitation at all in his swings, so he's feeling good enough to hit and hopefully that will continue," Picollo said.

There was no immediate indication on when Infante might rejoin the Royals, who are in Milwaukee for their last two exhibition games on Friday night and Saturday afternoon.

Infante, bothered earlier in training by a sore shoulder, played just eight Cactus League games in Arizona. He has yet to play in a game with his new shortstop partner, Alcides Escobar.

Royals return reliever Schuster to D-backs

Matthews and Lefebvre talk about Royals' expectations

MILWAUKEE -- The Royals returned left-handed reliever Patrick Schuster to the D-backs just two days after claiming him on waivers from the Padres.

Schuster's trail has been complex this winter. On Dec. 12, he was selected in the Rule 5 Draft of Minor League players from the D-backs by the Astros. On the same day, the Astros traded him to the Padres for pitcher Anthony Bass.

Last Tuesday, the Royals claimed him off waivers from the Padres. Then, on Thursday, the Royals returned him to the D-backs. If the Astros, Padres or Royals had elected to keep Schuster, because of Rule 5 stipulations, they would have been obligated to keep him on their Major League roster the entire 2014 season. The move opens a spot on the Royals' 40-man roster.

The D-backs assigned Schuster, 23, to Triple-A Reno. He's pitched for Visalia in the Class A California League the last two years.

Meanwhile on Thursday in Arizona, left-hander Danny Duffy had an impressive outing for Triple-A Omaha against Dodgers Minor Leaguers. Duffy will be in the Storm Chasers' starting rotation.

"He threw four innings and looked very good," said Scott Sharp, the Royals' director of player personnel. "He was very sharp, faced maybe two guys over the minimum, threw the ball very well."

The Royals released right-hander Jon Rauch, a non-roster player cut from the Major League camp earlier this week and assigned to the Minor Leagues. Rauch, 35, has put in 11 years in the Majors.

"We felt we had enough depth in Triple-A with young guys that we wanted to get there," Sharp said.
