Roman Colon, Greg Atencio and Brad Salmon combined on a six-hit shutout and Kila Kaaihue homered to lead the Royals to a 4-0 win over Colorado Springs Sunday afternoon at Rosenblatt Stadium.

Colon (3-5) went five innings, giving up four hits and one walk while striking out five. Atencio gave up one hit and a walk over three, striking out six and Salmon pitched the ninth inning, surrendering one hit, one walk and struck out one.

Kaaihue's home run in the second inning off Sean Smith (4-4) was all the offense Omaha would need.

Chris Lubanski singled home Mike Stodolka in the fifth to make it 2-0. The Royals scored twice in eighth. Lubanski tripled home Angel Sanchez and scored on Gookie Dawkins' sacrifice fly.
