Defending champions and world number one United States crushed Thailand 13-0 to record the biggest victory in FIFA Women's World Cup history.
With the US topping the FIFA world rankings, Thailand were always considered the underdogs, sitting 34 places below their opponents.
America's dominance in the Group E clash at Stade Auguste-Delaune in Reims exceeded expectations, however.
Alex Morgan had scored the first for her side in the 12th minute, with Rose Lavelle and Katie Horan grabbing a goal each to put the US 3-0 up at half-time.
America started the second-half in much the same way, with Samantha Mewis hitting the back of the net in the 50th minute.
From there Thailand capitulated, with Morgan scoring again three minutes later, followed by Mewis and Lavelle in quick succession.
Morgan earned her hat-trick in the 74th minute but did not stop there, getting another two before the final whistle.
Further goals from Megan Rapinoe, Mallory Pugh and Carli Lloyd ensured their side's record-breaking victory.
The previous record had been held by Germany, who thrashed Argentina 11-0 at the World Cup in 2007.
The US are seeking their third World Cup title, having triumphed in 1991, 1999 and 2015.
Elsewhere in Group F, Sweden and Chile had to battle with the weather at Stade de la Route de Lorient in Rennes.
At 0-0, both teams were taken off the pitch in the 72nd minute due to the stormy conditions.
Forty minutes later, play resumed again, with the enforced break appearing to benefit Sweden the most.
Kosovare Asllani and Madelen Janogy got on the score-sheet before the final whistle, securing a 2-0 victory for the Swedes.
European champions The Netherlands left it until the very last minute to score the winner against New Zealand.
