Just when you thought Megan Rapinoe's spectacular performance at the World Cup couldn't get any better, the U.S. women's national team co-captain scored the game-winning goal in the Americans' 2-0 win over the Netherlands in Sunday's final.

Rapinoe, who missed last week's semifinal win over England with a hamstring injury, finished the World Cup with six goals, tying her with teammate Alex Morgan and England's Ellen White for most in the tournament. She became the second American to win the tournament's Golden Boot award, and also won the Golden Ball as the tournament's most valuable player.

"It's unbelievable," Rapinoe, who became the oldest player to score in a Women's World Cup final at age 34, told Fox after the game. "Just to know all of the people in our group that put in so much work, obviously the players. We have all our friends and family here. It's surreal. I don't know how to feel right now. It's ridiculous."

Rapinoe opened the scoring on Sunday by sending a penalty kick past Dutch goalie Sari van Veenendaal in the 61st minute. The penalty was awarded after referee Stephanie Frappart went to VAR to review a possible foul on Netherlands defender Stefanie van der Gragt, who caught Morgan in the right shoulder area with a high boot inside the box. Frappart issued van der Gragt a yellow card and Rapinoe converted her third penalty kick of the tournament. It was her 50th career international goal.

Rapinoe, long outspoken on a variety of political and social issues, has been particularly vocal about President Donald Trump and her efforts to improve human rights. She issued an impassioned defense last week of her comments and actions about politics and patriotism, and was sharply critical on Saturday of the decision to hold multiple tournament finals on the same day as the World Cup championship game.

After the Americans won their fourth World Cup title, and second in a row, Rapinoe was asked what makes this group special.

"I don't know," she said. "We're crazy. That's what makes us special. We just have no quit in us. We're so tight and we'll do anything to win."
