Atlanta switched back to Hedberg in Game 4 and struck first to take their first lead of the series with a Keith Tkachuk goal in the first period. The Rangers would respond just over a minute later with Michal Rozsival's second power play goal of the series to make the score 1–1 after one period. Atlanta would take the lead for a second time in the second period on a goal by Greg de Vries, but the Rangers would counter again, this time with a Brendan Shanahan goal to tie the game at 2–2 after two periods. Early in the third period Matt Cullen would score the eventual game winner, driving a rolling puck from the point off the crossbar. The puck bounced straight down and at first glance never crossed the goal line. After a five-minute video review, the puck was clearly shown to have crossed the line in its entirety while on edge and the goal counted. Jaromir Jagr added an empty net goal late in the period to seal a 4–2 win and a series sweep. The sweep was only the third sweep of a seven-game playoff series in franchise history (the other sweeps came against the Chicago Blackhawks in 1972 and the New York Islanders in 1994).
