The Kansas City Royals have tentatively agreed to a one-year deal with Rick Ankiel, a former pitcher turned power-hitting center fielder with the cross-state rival St. Louis Cardinals.

According to MLB.com, Ankiel has agreed to a one-year $3.25-million contract with the Royals with a mutual option on a $6 million contract for 2011.

According to a source close to the negotiations, the deal includes a base salary of $2.75 million for 2010 and the guaranteed figure inflates to $3.25 million with a $500,000 buyout on the mutual option.

The deal is dependent on Ankiel, a free agent, passing a physical examination Monday.

Ankiel, in addition to helping the Royals improve their defense, brings a left-handed bat with power potential. In 2008, his first full year as a big league outfielder, he belted 25 homers and 21 doubles with 71 RBIs and a .264 average for the Cardinals.

Last season, in an injury-plagued 122 games, he had just 11 homers and 38 RBIs while batting .231.

Ankiel began his career as a left-handed pitcher with the Cardinals, finishing second in the balloting for Rookie of the Year in 2000 when he went 11-7 with a 3.50 ERA with 194 strikeouts in 175 innings.

He later abandoned pitching, announcing his decision to attempt a comeback as a hitter in March 2005 before making his Major League debut as an outfielder on Aug. 9, 2007.

In parts of three seasons as an outfielder with the Cardinals, Ankiel was a .255 hitter with 47 home runs and 148 RBIs in 289 games. Overall, including his at-bats as a pitcher, he is a career .251 hitter with 49 home runs and 157 RBIs in 342 games.
