Tsitsipas enters this National Bank Open second-round clash on outdoor hard courts riding momentum from his first ATP title in 16 months at Gstaad on clay and a straight-sets opening win over Martin Damm. The Greek veteran, ranked near No. 52 after earlier 2026 struggles, faces a rematch against 22nd-seeded Fonseca, who leads their head-to-head 1-0 from a Davis Cup hard-court win last September. Fonseca, ranked around No. 25-27 and showing strong recent form, brings youth, athleticism, and baseline power that suits the fast Montreal surface, though Tsitsipas's improved serving and experience in high-stakes Masters matches create a competitive dynamic where recent results and physical freshness will likely decide the outcome.
