ATP 250 Adelaide 1/8-Finals

Griekspoor – Humbert: 14.01.2026 02:00 CEST
H2H: 1-1

Tallon Griekspoor has lost four of his last five matches. So far this season, Griekspoor played in the United Cup, losing both singles matches against Zverev and Hurkacz in straight sets. This is his debut campaign in Adelaide.

Ugo Humbert has lost three of his last five matches. So far this season, Humbert played in Brisbane, where he lost to Norrie in the opening match in three tight sets. This is his second appearance in Adelaide and his first appearance in the main draw here. In the opening round, the Frenchman defeated Atmane in straight sets as we predicted.

Best Bet to Make

According to the bookies, Humbert is the slight favourite in this matchup, and we agree. He started this season better than Griekspoor and dominated his opening match in Adelaide. He will be better adapted, so we expect him to get a comfortable win.

That being said, Humbert winning is a value bet.

Value bet/ the best odds: Ugo Humbert winning @1.62 @bet365

Opelka – Paul: 14.01.2026 02:00 CEST
H2H: 2-1

Reilly Opelka has lost three of his last five matches. Last week in Brisbane, Opelka lost to Majchrzak in the second round in three tight sets. This week in Adelaide, Opelka defeated Popyrin in the opening round in straight sets. He offered and saved only one breakpoint.

Tommy Paul has lost three of his last five matches. In his opening match of the season in Brisbane, Paul lost to Mpetshi Perricard in three tight sets. Last season in Adelaide, the American lost to Auger-Aliassime in the semifinals in three tight sets.

Best Bet to Make

According to the bookies, Paul is the slight favourite in this matchup, but we disagree. Opelka served well in the opening match and leads 2-1 in head-to-head meetings. If he serves well, we expect him to keep this match close.

That being said, Opelka covering the games handicap is a value bet.

Value bet/ the best odds: Reilly Opelka +1.5 games handicap @1.91 @bet365

Kokkinakis – Vacherot: 14.01.2026 09:00 CEST
H2H: first meeting

Thanasi Kokkinakis has won three of his last five matches. The last match he played before the ATP Adelaide was previous season at the Australian Open, where he lost to Draper in the second round in five tight sets. Kokkinakis upset Korda this week in Adelaide in three tight sets, after losing the opening set 3-6.

Valentin Vacherot has lost three of his last five matches. Last week in Brisbane, Vacherot lost to Korda in the opening round in straight sets. This is his debut campaign in Adelaide. In the opening round, Vacherot defeated Kecmanovic in the opening round in straight sets. He trailed 0-2 in the opening round, but turned it around.

Best Bet to Make

According to the bookies, Vacherot is the favourite in this matchup, and we agree. Kokkinakis was visibly tired after winning a three-set thriller. On the other hand, Vacherot continued playing well as he did last season. We expect Vacherot to be a better player tomorrow.

That being said, Vacherot covering the games handicap is a value bet.

Value bet/ the best odds: Valentin Vacherot -3.5 games handicap @1.83 @bet365
