The 2026 ATP and WTA seasons begin with the opening day of the United Cup. Naomi Osaka\u2019s Team Japan will face Stefanos Tsitsipas\u2019s<\/a> Team Greece in Perth, after Team Spain\u2019s tie with Team Argentina. We here at LWOT predict the confirmed matches in this article, but which players do you think will win?<\/p>\n

United Cup Day 1 Predictions
\nJaume Munar vs Sebastian Baez<\/p>\n

Head-to-head: Baez 1-0 Munar<\/p>\n

Munar is generally the more comfortable of this pair on hard courts, despite Baez\u2019s title in Winston-Salem just over two years ago. The Argentine will try to bring his powerful forehand into play consistently. If the conditions are similar to previous years in Perth, that will favor Munar more. He is slightly favored in a contest that will contain several lengthy rallies.
Prediction: Munar in 3<\/p>\n

Jessica Bouzas Maneiro vs Solana Sierra<\/p>\n

Head-to-head: Bouzas Maneiro 1-0 Sierra<\/p>\n

Both women grew up on clay, and it remains their favored surface. However, Bouzas Maneiro is more accomplished on other surfaces and has more firepower. Sierra is a fighter, but she can only win if her higher-ranked opponent underperforms. I think Bouzas Maneiro will prevail, and, if Munar also triumphs, give Spain an unassailable 2-0 lead before the doubles.
Prediction: Bouzas Maneiro in 2<\/p>\n

Stefanos Tsitsipas vs Shintaro Mochizuki<\/p>\n

Head-to-head: First meeting<\/p>\n

A strong start to 2026 feels particularly important for Tsitsipas. Question marks surround the 2023 Australian Open<\/a> runner-up after a poor 2025 and persistent back issues. If the Greek is unsteady from the baseline, Mochizuki\u2019s usual consistency will make this a challenging match. Tsitsipas\u2019s past results in Australia make me back him, but that is not with complete confidence.
Prediction: Tsitsipas in 3<\/p>\n

Naomi Osaka vs Maria Sakkari<\/p>\n

Head-to-head: Osaka 3-2 Sakkari<\/p>\n

Osaka finished 2025 impressively<\/a> under Iga Swiatek\u2019s former coach, Tomasz Wiktorowski, with final and semifinal runs at the National Bank Open and the US Open. At her best, the four-time Grand Slam champion\u2019s powerful game will overwhelm Sakkari, who struggles against pace. Sakkari\u2019s inconsistent past couple of years are another reason not to be optimistic about her chances.
Prediction: Osaka in 2<\/p>\n
