Brazil Women 3-0 Jamaica Women
Veteran Brazil striker Cristiane scored the first hat-trick of the 2019 Women's World Cup as Jamaica's tournament debut ended in a 3-0 defeat in Grenoble.
The South American champions were missing legendary forward Marta, the leading scorer in Women's World Cup history, through injury.
But they got their Group C campaign off to a flying start as Cristiane headed the first before tapping home a second.
The 34-year-old sealed her hat-trick with a superb free-kick.
In front of a 17,000 crowd at Stade des Alpes, Brazil could even afford to miss a penalty, Jamaica's 19-year-old keeper Sydney Schneider saving Andressa Alves' weak attempt when the score was 1-0.
It was awarded after Allyson Swaby handled inside her own area.
The win lifted Brazil to the top of group, level on points with Italy, who came from behind to beat Australia 2-1 earlier in the day.
Brazil would have won by a bigger margin but for Schneider.
The Jamaica keeper twice denied Debinha when the Brazilian forward was through on goal.
Jamaica's most dangerous player was Khadija Shaw who was denied a first-half equaliser by a one-handed save from Barbara.
Brazil's side included Formiga, the midfielder becoming the first player to appear at seven Women's World Cup finals, and the oldest player in the tournament's history at 41 years and 98 days.
Brazil head for Montpellier where they face Australia on Thursday (17:00 BST) while Jamaica's second Group C game is in Reims on Friday against Italy (17:00).
