Royals bringing up 1B Eric Hosmer

KANSAS CITY, Mo. -- Eric Hosmer, the top prospect in the Kansas City Royals' talent-rich minor league system, will start at first base on Friday night in his major league debut.

The Royals made the announcement moments after their 9-1 victory on Thursday over the Baltimore Orioles. He will replace the struggling Kila Ka'aihue at first base.

The Royals' first-round draft pick in 2008, Hosmer was hitting .439 for Triple-A Omaha with three home runs and 15 RBIs in 26 games. He had a slugging percentage of .582.
