RD Rafael Delvar The Porto Improviser

About

From the tiled streets of Porto to the ISTC Obsidian Tour

Creative, improvisational, emotional — Rafael Cian Delvar plays tennis the way Porto paints its walls: in patterns nobody else would think to try.

Rafael Delvar is one of the more creative match players in the ISTC field. His game relies on changing speed, height and rhythm rather than overpowering opponents — a habit that makes him a genuinely awkward matchup on clay and on low-bouncing grass courts, where his skidding slice refuses to sit up and be hit.

Born in Porto on October 9, 2001, Rafael grew up at the Porto Redline Tennis Academy, where coaches gave up early on straightening out his shot selection and decided instead to sharpen it. The result is a variety-based all-court game anchored by a one-handed backhand: the knifed slice, the disguised drop shot, the sudden change of height that turns a neutral rally into a scramble.

He doesn’t hit through opponents. He redraws the court until they stand in the wrong place.

Rafael turned professional in 2020 after a season as No. 2 singles on the Atlantic Navigators development circuit, and studied Sport Communication and Strategy at Atlantic Sport and Design College — a degree he says taught him “how to tell a story, which is also how you build a point.” A finalist at the 2022 Embergate Futures Crown, he broke through with a semifinal at the 2024 Port Azure Open and reached a career-high singles ranking of No. 33 in October 2025.

Now based in Lisbon, he works with coach Tiago Morel on turning creativity into consistency, while fitness coach Ruben Avelar handles the legs that make the improvisation possible. His touch also travels in pairs: with a 62–48 career doubles record, Rafael is currently ranked a career-best No. 38 in ISTC doubles — higher than his singles ranking of No. 46. The main threat to his game remains the one his team names openly: flat, first-strike baseline hitters who refuse to let the puzzle begin.
