Former Dartmouth forward Lee Stempniak put the United States ahead, but Russia came storming back for a 4-1 victory Saturday in the qualification round of the World Championship.
The Americans can still advance to the quarterfinals with a victory over Switzerland on Monday.
Stempniak scored 3:16 into the first period, but Oleg Saprykin started Russia’s response less than two minutes later.
Robert Esche made 28 saves for the Americans.
Russia scored three times on seven power play chances.
