Brock Nelson scored twice as United States secured a third successive IIHF Ice Hockey World Championship match by beating Italy 3-0, while Finland bounced back in resounding fashion.
New York Islanders center Nelson opened the scoring in the sixth minute of the first period before doubling his tally with the US shorthanded in the second.
After Jack Eichel was penalised for roughing, Nelson forced a turnover and combined with Dylan Larkin to extend their advantage and Anders Lee rounded off the scoring in a powerplay less than two minutes later.
The US joined Latvia at the top of Group A on nine points, but the Baltic nation have played a game fewer.
Last year's runners-up Finland recovered from back-to-back defeats against France and Czech Republic with a 5-2 thumping of Slovenia.
Slovenia led at the end of the first period but Finland fought back, goals from Sebastian Aho and Markus Hannaikainen within 64 seconds of one another in the third proving decisive.
Finland remain behind joint-Group B leaders Switzerland after they inflicted a fourth straight defeat on Belarus by winning 3-0 in Paris, while co-hosts Germany had Dominik Kahun's penalty shot to thank for a dramatic turnaround to win 3-2 against Slovakia.
