Catcher Miguel Olivo signed a one-year contract with the Kansas City Royals on Thursday. The 29-year-old was the Florida Marlins' primary catcher the past two seasons and batted .237 in 2007. Olivo was not tendered a contract by the Marlins before becoming a free agent. Florida acquired catching prospect Mike Rabelo from Detroit in a trade this month. The Royals and Olivo each hold options for the 2009 season. Terms of the deal were not disclosed. The 6-foot, 220-pound Olivo has thrown out 31.2 percent of attempted base stealers the past two seasons, the fourth-best in the National League. Olivio also has played for the Chicago White Sox, Seattle Mariners and San Diego Padres, hitting .239 in his career with 61 home runs and 224 RBI in 556 games.
