The Colorado Rockies claimed right-handed pitcher Sun Woo Kim off waivers from the Washington Nationals on Friday. Kim will report to the Rockies either Saturday or Sunday, and the team will then make a corresponding roster move. The 27-year-old Kim played in just 12 games for the Nationals this season, going 1-2 with a 6.14 earned run average. He opened the season with Triple-A New Orleans, going 4-2 with a 2.76 ERA in nine starts.
