L'Alliance de Montréal vient de réaliser une signature majeure pour la franchise, annonçant aujourd’hui que le meneur dynamique Keeshawn Barthelemy, natif de Montréal, rejoindra l'équipe pour la saison 2026 de la Ligue élite canadienne de basketball (LECB). Fort d’une expérience NCAA, internationale et professionnelle, Barthelemy revient dans sa ville natale pour entamer un nouveau chapitre de sa carrière. « Keeshawn est un joueur de grande qualité humaine, qui apporte calme, compétitivité et une excellente lecture du jeu », a déclaré Joel Anthony, directeur général et copropriétaire de l’Alliance. « Il a évolué à un très haut niveau, il a continué de progresser comme professionnel, et le fait d’accueillir un joueur montréalais de retour à la maison avec cette expérience est très significatif pour notre organisation. Nous croyons qu’il correspond parfaitement à ce que nous construisons. » Le meneur de 6 pi 1 po et 180 livres arrive à Montréal après un passage remarqué avec Proteas EKA AEL, dans la Division A chypriote, lors de la saison 2025-2026. En 10 matchs professionnels, Barthelemy a maintenu des moyennes de 13,8 points, 3,0 passes décisives, 2,8 rebonds et 1,1 interception par rencontre, se classant au troisième rang de son équipe pour les points marqués, tout en assumant un rôle clé comme meneur de jeu et en offrant une contribution constante des deux côtés du terrain. Son impact s’est fait sentir tout au long de la saison, notamment grâce à plusieurs performances à deux chiffres, dont une sortie de 27 points contre Morphou. Âgé de 25 ans, Barthelemy a connu un parcours universitaire remarquable dans la NCAA, amorçant sa carrière à l’Université du Colorado avant de la conclure à l’Université de l’Oregon. En cinq saisons, il a disputé 140 matchs, obtenant plusieurs départs et s’imposant comme un marqueur fiable et un meneur capable d'orchestrer l'attaque. Lors de sa dernière saison universitaire à Oregon (2024-2025), Barthelemy a inscrit 10,0 points par match, tout en maintenant un taux de réussite de 41,4 % derrière l’arc. Son efficacité offensive et aux lancers francs le classaient parmi les meilleurs de sa conférence. Barthelemy apporte également une précieuse expérience internationale, ayant représenté Équipe Canada sur plusieurs scènes, notamment lors de la Coupe du monde FIBA U17 en 2018 ainsi qu’au tournoi Global Jam en 2022. « Revenir à Montréal pour jouer au niveau professionnel, c’est quelque chose dont j’ai toujours rêvé », a confié Barthelemy. « C’est ici que tout a commencé pour moi, et pouvoir porter le chandail de l’Alliance devant ma famille, mes amis et les partisans, c’est vraiment spécial. J’ai très hâte à la nouvelle saison, à ce que l’équipe est en train de bâtir, et je suis prêt à me mettre au travail. » Cette signature représente un moment marquant pour l’Alliance, qui ramène à la maison un joueur montréalais dont le parcours l’a mené des gymnases locaux à la NCAA, puis au basketball professionnel à l’étranger. Tout au long de sa carrière, Barthelemy est demeuré profondément lié à la ville qui l’a formé, représentant fièrement le Québec et le Canada sur les scènes nationale et internationale. Son retour renforce l’engagement de l’Alliance à bâtir une équipe qui reflète à la fois le talent et l’identité de Montréal, alors que l’organisation poursuit sa progression en vue de la saison 2026. La prochaine saison comptera 12 matchs à domicile pour l’Alliance à l'Auditorium de Verdun, en plus d’un nouveau format de séries éliminatoires à l’échelle de la ligue, qui culminera avec une finale de la LECB deux de trois. L’Alliance disputera son match d’ouverture à domicile le 15 mai, face aux Shooting Stars de Scarborough. Pour plus d’information sur les forfaits de billets disponibles, visitez BASKETMTL.ca. ###

The Montréal Alliance has made a key signing for the franchise, announcing today that dynamic guard Keeshawn Barthelemy, a Montréal native with NCAA, international, and professional experience, has signed with the team for the 2026 Canadian Elite Basketball League (CEBL) season. “Keeshawn is a high-character player who brings poise, competitiveness, and a strong feel for the game,” said Joel Anthony, General Manager and co-owner of the Alliance. “He’s played at a high level, he’s continued to grow as a professional, and having a Montreal-born player return home with that experience means a lot to this organization. We believe he’ll be a great fit for what we’re building.” The 6'1", 180-pound guard brings professional experience after most recently competing with Proteas EKA AEL in the Cyprus Division A, where he made an immediate impact during the 2025–26 season. In 10 professional games, he averaged 13.8 points, 3.0 assists, 2.8 rebounds, and 1.1 steals per game, ranking third on the team in scoring while serving as a primary ball handler and reliable two-way contributor. His impact was evident throughout the season, scoring in double figures on multiple occasions, highlighted by a 27-point performance against Morphou. The 25-year-old guard built an impressive collegiate career in the NCAA, beginning at the University of Colorado before finishing at the University of Oregon. Across five seasons, he appeared in 140 games, earning multiple starting roles and developing into a consistent perimeter scorer and playmaker. In his final collegiate season at Oregon (2024–25), Barthelemy averaged 10.0 points per game while shooting 41.4% from three-point range, ranking among the conference leaders in efficiency and free throw percentage. Barthelemy also brings valuable international experience, having represented Team Canada on multiple occasions, including at the 2018 FIBA U17 World Cup and the 2022 Global Jam Tournament. “Coming back to Montreal to play professionally is something I’ve dreamed about,” said Barthelemy. “This city is where everything started for me, and to put on an Alliance jersey in front of my family, friends, and the fans is really special. I’m excited for the new season, excited for what this team is building, and ready to get to work.” This signing marks a significant milestone for the Alliance, bringing home a Montréal native whose journey has taken him from local gyms to the NCAA and the professional ranks overseas. Throughout his career, Barthelemy has remained connected to the city that shaped him, proudly representing Québec and Canada on the national and international stage. His return reinforces the Alliance's commitment to building a team that reflects both the talent and the identity of Montréal as the organization builds toward the 2026 season. The upcoming season will include 12 home contests for the Alliance at the Verdun Auditorium and a new league-wide playoff format that culminates in a best-of-three CEBL Final. The Alliance will play its home opener on May 15 against the Scarborough Shooting Stars. For more information on available ticket packages, visit BASKETMTL.ca. ###
