"Lucas Picquery sent the Bludger into the face of Keeper Susan Blancheflower in the fourth hour of the game...."
-- Ginny Weasley reporting for the Daily Prophet, 4 July 2014 (Pm)

Lucas Picquery was a Beater for the United States National Team at the 2014 Quidditch World Cup.
Part of the team representing the United States in the 2014 Quidditch World Cup, Picquery participated in the winning matches against Jamaica (240 points to 230) and Liechtenstein (450 points to 290) (Pm).
The two-day match against Brazil saw mis-hit Bludgers, including from Picquery. The US team lost this semi-final match by 420 points to 310 (Pm).
They also lost their final match against Japan by 330 points to 120, leaving the Americans in fourth place overall (Pm).
Other canon notes and references
Since Viktor Krum, born 1976, was the oldest player at the tournament (Pm), Picquery must have been born after 1976.
Commentary
Etymology
Lucas is either a Latin name derived from Lucius (lux "light") or from the Greek Λουκας (Loukas, Loukanos) "man from Lucania (in Southern Italy)" (Behind the Name).
Picquery is of unknown origin, but Lucas shares the surname with Seraphina Picquery, a President of MACUSA in the 1920s.
Notes
As he comes from the USA, Piquery may have attended the Ilvermorny School of Witchcraft and Wizardry.
