FRISCO, Texas -- The Royals' pre-Spring Training logjam at first base was officially unclogged on Friday.

Ryan Shealy cleared outright waivers and was assigned outright to Triple-A Omaha. Shealy is hitting .262 (11-for-42) this spring with four home runs and nine RBIs. He will remain with the Royals for their last two Cactus League games in Texas before reporting to Omaha.

Last September, Shealy jumped back into the picture when he arrived from Omaha and blasted seven home runs with 20 RBIs and a .301 average in 20 games.

"It is [disappointing]," Shealy said. "I played real well in September, and I'm healthy and swinging the bat fine. I hit a few home runs [this spring]. It's discouraging, because as a player, you want to be in the big leagues, especially when you get to be my age [29] and you've been up there, and you know you can play there, but sometimes circumstances, and the numbers just don't add up."

Of other potential first basemen when camp began, Kila Ka'aihue was optioned to Omaha, Ross Gload was traded to Florida and Mark Teahen became a second baseman.

Of the original six, that leaves Billy Butler and Mike Jacobs to share first base and designated hitter.

"You couldn't wish any more good things on anybody than Shealy," manager Trey Hillman said. "The business side of it didn't work out to his advantage, and he's a pro, and he'll just keep doing what he's done."

In addition, pitcher Joel Peralta has cleared unconditional release waivers and is a free agent.
