Junior Mailly (born 18 December 1998) is a French professional footballer who plays as a winger.
Mailly grew up in Paris, France, and played for various club academies in Europe, including the youth team of Boulogne-Billancourt. In 2018, his family moved to Nevada in the United States.
After moving to the US, Mailly lived in Reno, Nevada. There, he played football for Battle Born FC, a developmental football team, for one season.
In 2022, he tried out for the San Francisco Glens of the USL League Two, and was the only player from tryouts that day to make it to the team. In his first season with the club, he netted five goals in nine matches. He would renew for another season before departing in early 2024.
In late 2023, Mailly participated in a combine led by Anton del Rosario, aimed at giving US-based players a chance to play for teams in the Philippines Football League. Mailly signed with del Rosario's team Maharlika Taguig shortly after as a foreign reinforcement for the 2024 season.
He made his debut for the club in the opening matchday against Tuloy, where Maharlika won 3âÂÂ2. He scored his first goal for the club in a 4âÂÂ2 win over Philippine Air Force, and scored a hat-trick the following matchday in a 3âÂÂ1 win over Don Bosco Garelli.
