Gabriel Diallo vs Chun-Hsin Tseng prediction

Both players are coming off the back of decent tournaments in Miami, with both getting past the qualifiers before exiting at the round of 64 stage, with Gabriel Diallo having to retire in his match against Arthur Fils despite being up in the second set after narrowly losing the first. 

Meanwhile, Chun-Hsin Tseng defeated Mattia Bellucci in the first round before losing out in a hard-fought three set battle to two-time Grand Slam finalist Stefanos Tsitsipas, while he also entered a clay court Challenger event in Napoli a week later, which saw him lose in the round of 16 to Dalibor Svrcina.

This is the first clay court event for the Canadian player, which could give the edge to Tseng, who has already participated in three clay court tournaments already this year, with his strongest finish being a quarter-final appearance at the Rio Open against Sebastian Baez, who went on to win the tournament.

Diallo is the higher ranked player of the two but neither have played each other before and it will likely be a close-fought match between the pair, but we lean towards Tseng who has the most recent experience on the surface.
