#NextGenATP star Chun-hsin Tseng earned his third tour-level win of the season Monday, moving past American qualifier Nick Chappell 6-4, 6-4 to reach the second round at the Abierto de Tenis Mifel in Los Cabos.
The 20-year-old produced a strong serving performance as he quickly found his range on debut at the ATP 250 event. Tseng of Chinese Taipei won 84 per cent (27/32) of points behind his first delivery, while he did not face a break point to advance after one hour and 31 minutes.
Tseng, who is up to No. 81 in the Pepperstone ATP Live Rankings, will next play third seed Cameron Norrie. The Briton captured the title in Mexico last season.
Earlier this season, Tseng lifted ATP Challenger Tour trophies in Bangalore and Murcia, before he made his debut at Roland Garros after coming through qualifying. The 20-year-old is currently eighth in the Pepperstone ATP Race To Milan as he aims to qualify for the Intesa Sanpaolo Next Gen ATP Finals for the first time.
In other action, Australian qualifier Max Purcell clinched his first tour-level hard-court win of the year, downing Swiss Henri Laaksonen 6-3, 3-6, 6-4 in two hours and four minutes.
Purcell, who advanced to the second round on grass in Newport last month, will play #NextGenATP American Brandon Nakashima or qualifier Kaichi Uchida in the second round.
Lithuanian Ricardas Berankis gained revenge against Quentin Halys, advancing 7-6(1), 7-5 in one hour and 52 minutes. Berankis, who lost to Halys in Pune in January in their only previous ATP Head2Head meeting, will next take on Facundo Bagnis or Ernesto Escobedo.
Australian qualifier Rinky Hijikata set a second-round meeting against World No. 1 Daniil Medvedev after Mexican wild card Rodrigo Pacheco Mendez was forced to retire. The 21-year-old Hijikata was leading 6-3, 4-0 when the match was stopped.
