Greek superstar Stefanos Tsitsipas begins his North American hard court swing with a teaser of a test against Christopher O’Connell of Australia on Wednesday. The duo will face each other for the first time in their careers at the 2025 National Bank Open Round of 64 in Toronto. Continue reading to know all about our predictions, as well as the BetMGM betting odds for this match-up.

Stefanos Tsitsipas vs Christopher O’Connell Match Preview

With all the talk being around his split with coach Goran Ivanisevic as well as alleged rift with Paula Badosa, Stefanos Tsitsipas will be hoping for a strong outing in Canada. The 26-year-old is a former runner-up at this event, losing in the 2018 final vs Rafael Nadal. He started this year with a statement title charge at the Dubai Open, and followed it up with multiple quarterfinals. However, Tsitsipas has picked up just one win in the three Grand Slams in 2025 so far. The World No. 30 has a 19-13 record so far, including a two-match losing streak at present.

On the other hand, Christopher O’Connell is ranked No. 78 in the world. Yet to win an ATP Tour title so far, the Australian produced a ruthless performance to beat Tseng 6-1 6-2 in Round-1. The 31-year-old reached the last eight in Bucharest, as well as pre-quarterfinals in Adelaide, Doha and Dubai. O’Connell has a 10-7 record on hard courts this year, including a 79% service game win percentage on the surface. He will be hoping to beat his Round of 32 personal best at Flushing Meadows (2024) this year.

Stefanos Tsitsipas vs Christopher O’Connell ATP National Bank Open 2025 Prediction

Tsitsipas has done well at the Canadian Open over the years. The former World No. 3 enjoys the higher bounce and slower nature of the court over the years. He also has the endurance to outlast most of his ATP counterparts, making it difficult for O’Connell to stick with him under the hot conditions in Toronto. The Australian will target the single-handed backhand of Tsitsipas, and look to draw him into the net. Unfortunately, all roads seemingly lead to a Tsitsipas win on Wednesday.

Prediction: Stefanos Tsitsipas in straight sets.

Just found out I'm the villain in someone’s story. Finally.
