At the 2019 Rio Open, Dellien defeated Carlos Berlocq in qualifying competition, Guido Andreozzi in the first round, and Roberto Carballés Baena in the second to reach the quarterfinals recording his first ATP main draw wins.[5] Hugo became the first Bolivian player with an ATP win since Martínez at the French Open in 1984, trailing 3–1 in both sets before performing a comeback against Andreozzi to secure a historic achievement for both him and his country.[8]

Ranked No. 128 at the 2021 Italian Open Dellien qualified for the main draw and recorded his second Masters win over world No. 36 Adrian Mannarino.[9]

2023: ATP semifinal, Struggling with form, out of top 150

He entered the 2023 Australian Open using protected ranking having not competed on the ATP Tour since July 2022. At the 2023 Córdoba Open, Argentina he reached again the quarterfinals as a qualifier defeating two Argentines, fifth seed Pedro Cachin[11] and Guido Pella.[12] Next he defeated 2021 champion Argentine Juan Manuel Cerundolo in three sets to reach his first ATP semifinal in his career.

At the 2023 Rio Open, also using a protected ranking, he reached the quarterfinals for a second time in four years at this tournament with a win over ninth seed Alex Molčan in the round of 16.
