Paredes, 25, was 2-for-10 (.200) with two stolen bases in nine games for the Royals earlier this season. In 65 games for Triple-A Omaha this year, he batted .305 with 36 RBIs, 18 doubles and 17 stolen bases.
Paredes (pronounced puh-RAY-diss) was briefly in the Orioles organization in spring training before the Royals claimed him off waivers Feb. 17. The Orioles had claimed Paredes off waivers from the Miami Marlins two days earlier.
In 377 at-bats through parts of four major league seasons, Paredes is hitting .233 with 13 doubles, 34 runs scored and 13 stolen bases. He spent the first three years of his major league career with the Houston Astros.
Making his major league debut for the Astros on Aug. 1, 2011, Paredes became the only player in club history to hit a triple in his first plate appearance, according to the Elias Sports Bureau.
Paredes played second base, third base and designated hitter for the Royals this year, but he primarily played right field last season with the Astros. He also has played shortstop, left field and center field in the minor leagues.
Paredes originially was signed by the New York Yankees in 2006 as a free agent out of the Dominican Republic. The Yankees traded him and relief pitcher Mark Melancon to the Astros for designated hitter-first baseman Lance Berkman at the July 31 nonwaiver trade deadline in 2010.
