Boston, MA -- (Sports Network) - The Boston Red Sox have traded outfielder Coco Crisp to the Kansas City Royals for right-handed reliever Ramon Ramirez.

The 29-year-old Crisp hit .283 last season with seven home runs, 41 RBI and 55 runs scored. His value, though, is more in the field than at the plate, but he became expendable with the emergence of Jacoby Ellsbury.

In three seasons with the Red Sox, Crisp hit .271 with 21 homers and 137 RBI.

Crisp, who will earn $5.75 million this coming season and has an $8 million club option with a $500,000 buyout for 2010, enjoyed his best season in 2005 with Cleveland when he set career highs, hitting .300 with 16 home runs and 178 hits. He also knocked in 69 runs that year.

Over 783 games in seven big league seasons, Crisp is a career .280 hitter with 56 home runs and 313 RBI. He has also stolen 124 bases and has been caught just 46 times.

Ramirez, meanwhile, appeared in 71 games for the Royals last season and was 3-2 with a save and a 2.64 earned run average. He spent the first two years of his career in Colorado and is 9-7 lifetime with a 3.62 ERA in 154 games.

The 27-year-old hurler is not yet arbitration eligible.
