Key moment: The Blues had the lead in the series and in the game. Until, that is, Blues defenseman Joel Edmundson made a pinpoint pass to Stars forward Radek Faksa at 4:05 of the second period. Edmundson was trying to get the puck out of the defensive zone but instead, after Faksa received the turnover, it ended up as a goal. The score was tied and Edmundson was left hitting his stick on the left post in frustration. It got the Stars back into the game at a time it might have spiraled.
Unsung player of the game:Stars goalie Kari Lehtonen. Dallas was in trouble, having pulled its goalie in each of the past two games. Lehtonen was pulled early in Game 2, and Antti Niemi got the boot early in Game 3. Though Lehtonen wasn't perfect in Game 4, he was good enough, allowing goals on a breakaway and a power-play redirect.
What's next: Game 5 comes quickly, with the Stars and Blues taking the ice at American Airlines Center in Dallas on Saturday afternoon (1 p.m. ET; NBC, TVA Sports, SN).
