Pitcher Sunny Kim lost to the Colorado Rockies on Thursday in the first salary arbitration case of the year and will earn $600,000 rather than the $800,000 he asked for. The decision was made by arbitrators Stephen Goldberg, Gil Vernon and John Sands, who heard the case a day earlier in St. Petersburg, Fla. A 28-year-old right-hander who earned the $316,000 minimum salary last season, Kim went 6-3 with a 4.90 ERA in 10 starts and 14 relief appearances for the Washington Nationals and Rockies. Colorado claimed him off waivers on Aug. 5.
