Season at a glance
The band got back together again and almost immediately went one better than they had before.
Between August 2019 and January 2022, Shuko Aoyama and Ena Shibahara won eight titles together and reached two Grand Slam semifinals and the last four of the WTA Finals. But the Tokyo Olympic Games had been the Japanese duo's target, but that had ended in a disappointing first-round loss. Five months later, they parted ways for the bulk of the 2022 season.
The time apart didn't go so well. Aoyama and Shibahara reached only one final each with different partners, and neither won a title. So they reunited at the start of 2023, and three tournaments in, they achieved something they hadn't in their original partnership -- a Grand Slam final at the Australian Open, sealed with a victory against Coco Gauff and Jessica Pegula.
Inconsistency plagued the remainder of the pair's season, but when they hit form they proved themselves a formidable team. This was ably demonstrated in their Montreal title run, which featured four victorious match tiebreaks in five matches.
