Valeri Nichushkin scored the tiebreaking goal with 7:58 left, and the Colorado Avalanche became the first team to advance to the second round Monday night by finishing a sweep of the Nashville Predators 5-3 Monday night. The Avalanche now are in the Western Conference semifinals for a fourth straight season and second consecutive after sweeping their first-round opponent. They improved to 6-0 since the franchise relocated to Denver in best-of-seven series after winning the first three games with their fourth sweep in that span.
