Winners of the week
One of the USA's brightest and most exciting talents, Iva Jovic, got her hands on a maiden WTA title, claiming a 6-4, 6-1 victory over Emiliana Arango in the final to reign victorious in Guadalajara.
The 17-year-old put in a really measured and accomplished performance against an opponent - and good friend - who was really struggling with illness.
With that triumph at WTA 500 level, the youngest player in the top 100 soared up to 36th in the rankings, firmly establishing herself as one of women's tennis' true up-and-coming stars. She is also the youngest player this season to win a trophy.
While she has a fantastic game, Jovic's willpower, tenacity and fighting qualities stand out at such a young age, and she had to display that throughout her title run, going the distance in three of her matches to get over the line.
The sky is the limit for her, and she will now be looking to carry this momentum through the tail of the season.
Jovic wasn't the only teen to have an incredible week. French 19-year-old Tiantsoa Sarah Rakotomanga Rajaonah captured her very first WTA title in Sao Paulo, dropping just a single set throughout the tournament. She defeated Indonesia's Janice Tjen 6-3, 6-4 in the showpiece event on Sunday.
Ranked 214th in the world ahead of the tournament, Rakotomanga Rajaonah's victory came out of the blue. She is the first French teenager to win a WTA-level event since Oceane Dodin in 2016, and as a result, has skyrocketed up to 131 in the world.
After Jovic's and Rakotomanga Rajaonah's victories, it is the first time since 2008 that two teenagers have won WTA events in the same week.
Away from the WTA Tour, there were also some Davis Cup qualifiers, as seven nations looked to join defending champions Italy in the Final 8.
Argentina, Belgium, Austria, Germany, the Czech Republic, Spain and France all ended up booking their spots in the final event, and remarkably, Spain were the only home team to win their tie.
The Spanish battled from a 2-0 deficit to clinch their win over Denmark, with Holger Rune failing to take a match point in the fourth rubber that would have seen the Danes over the line.
The USA, despite having Taylor Fritz and Frances Tiafoe on their side, were stunned by the Czechs, as Jiri Lehecka and Jakub Mensik led the way with some fine victories.
Australia's defeat to Belgium was also a major surprise, with Alex de Minaur suffering a shocking defeat to Raphael Collignon, which ended up being costly.
Strugglers of the week
The top three seeds in Guadalajara, Elise Mertens, Veronika Kudermetova and Jelena Ostapenko, all suffered losses in their opening matches, which left the door open for the rest of the field.
Ostapenko's defeat was particularly surprising. The former French Open champion fell to current world number 151, Marina Stakusic, 6-4, 6-7(6), 6-2 in the last 16, keeping up with her recent struggles, making it seven losses in her last 11 matches.
Meanwhile, Tiafoe has endured a really torrid 2025, and his Davis Cup performances summed up the slump he is currently in.
The American fell 6-3, 6-2 to Lehecka, before following that up the next day with a 6-1, 6-4 defeat to Mensik.
Frankly, his level was pretty low in both those rubbers, and coming off the back of a third-round defeat at the US Open - a tournament he usually thrives at - it might be time for him to go back to the drawing board.
Rallies of the week
Sao Paulo champion Rakotomanga Rajaonah won a truly astonishing rally in her semi-final match, showing fantastic athleticism before smoking a forehand winner down the line. Meanwhile, De Minaur once again displayed his unmatched foot speed at the Davis Cup.
Moment of the week
With their 3-2 victory over neighbours Hungary, Austria qualified for the Davis Cup Final 8 for the first time in their history.
World number 157 Jurij Rodionov was an absolute superstar for his nation, defeating both Fabian Marozsan and Marton Fucsovics, while world number 174 Lukas Neumayer also claimed an astonishing, near three-hour 6-3, 3-6, 7-6(7) win over Fucsovics.
A brilliant win for the underdogs, and they will now head to Italy for the Final 8 in November.
Upcoming events
The Asian hard-court swing is now underway in the tennis world, with the WTA Tour heading to Seoul for a 500 event. Headlining that tournament is world number two Iga Swiatek, second seed Ekaterina Alexandrova, as well as Barbora Krejcikova and Emma Raducanu.
On the ATP Tour, action gets underway from Wednesday in Chengdu and Hangzhou. Lorenzo Musetti is the number one seed at the former, while Andrey Rublev and Daniil Medvedev are the men to beat at the latter.
There are also some team tournaments to look forward to, with the main focus on the Billie Jean King Cup Finals. Reigning champions Italy lead a field with China, Spain, Ukraine, Kazakhstan, the USA, Japan and Great Britain, as several of the world's best players look to bring glory to their nation.
Jessica Pegula, Elena Rybakina, Jasmine Paolini and Emma Navarro will be in action, and it should be a brilliant week in Shenzhen.
There is also the Laver Cup towards the end of the week, as Team Europe defend their crown against Team World. The leading men for Europe will be world number one Carlos Alcaraz and Alexander Zverev, while Fritz and De Minaur lead the way for World.
