Danielle Collins was finally playing her best tennis, then her body got in the way

Danielle Collins hasn't played a competitive match since the first round of the 2025 US Open.

She isn't officially retired. She hasn't announced a comeback, either. At 32, Collins is instead somewhere in between, sidelined by a back problem while undergoing fertility treatment, with her ranking sitting in the 60s and her future on a tennis court uncertain.

That is a strange place for a player of her résumé to be. Collins is a Grand Slam finalist, a former world No. 7 and a Masters 1000 champion. In 2024, while supposedly playing the final season of her career, she produced the best tennis of her life.

Her story isn't one of a player who failed to reach her potential. It's about a player who reached extraordinary heights while constantly having to negotiate with her own body — and who finally found her best level at almost exactly the moment she thought she was leaving the sport behind.

Collins was never a conventional case. She didn't turn professional until after two NCAA singles titles at Virginia, arrived on tour in her mid-20s rather than her teens, and then spent the rest of her career compressing a normal athletic timeline into a shorter, more urgent one — racing against a chronic illness that never gave her the option of a leisurely prime.

Collins turned pro in 2016 with two NCAA titles already behind her, an unusual path in a sport that increasingly rewards leaving college early or skipping it altogether. It didn't slow her down much.

By January 2019 she was into the Australian Open semifinal as a virtual unknown, beating former No. 1 Angelique Kerber along the way before losing to Petra Kvitova. Two title runs arrived back to back in the summer of 2021, in Palermo and San Jose, part of a 12-match winning streak that was, at the time, the best stretch of her career.

That same year, 2021, Collins was diagnosed with endometriosis and underwent emergency surgery to remove a tennis-ball-sized ovarian cyst. She has spoken openly since about the condition and the toll it takes on daily life, well before it began shaping the biggest decisions of her career.

In interviews since, she's described the relief of finally understanding what had been happening to her body for years, saying she felt able to live a normal life again once she had a diagnosis to work with rather than unexplained pain.

Collins reached her only Grand Slam final at the 2022 Australian Open, losing to Ashleigh Barty in straight sets in what turned out to be Barty's last tournament before her own sudden retirement. Collins climbed to a career-high No. 7 that July. It looked, briefly, like the platform for a run at a maiden major.

Instead, endometriosis increasingly dictated the terms of her career. In January 2024, after a second-round loss at the Australian Open, Collins announced that the coming season would be her last, citing the physical toll of the condition and her desire to start a family before it became impossible.

What followed was one of the stranger twists in recent tennis memory. Playing with nothing to lose, Collins won the Miami Open two months later as an unseeded, 53rd-ranked entrant — the lowest-ranked champion in the tournament's history — beating Elena Rybakina in the final in front of her childhood idol Andre Agassi.

She won Charleston the following week, made the US Olympic team, and climbed back into the world's top 10, finishing the year 42-17. It was, by a distance, the best season of her career, produced entirely under the assumption that it was also her last.

That result complicated the goodbye. In October 2024, Collins reversed her decision and announced she would continue into 2025, citing ongoing fertility complications rather than a change of heart about retirement itself.

2025 offered no repeat of that magic. A recurring back injury limited her to a 15-14 record, her ranking slid outside the top 40, and her season ended quietly with a first-round US Open loss to Jaqueline Cristian — her last competitive match to date.

In December 2025, Collins confirmed she would miss the start of 2026, including the Australian Open where she'd once been runner-up, to continue recovering from the back injury and to undergo egg-freezing procedures tied to her endometriosis. She has since taken on a broadcasting role with Tennis Channel rather than commit to a return date.

None of that reads like a finished career, exactly — Collins has never said this is the end, and the WTA's newer protected-ranking rules for players undergoing fertility treatment exist precisely to make a comeback logistically possible. But taken together, the picture is unmistakable: a player who reached No. 7 in the world and won her biggest title while telling everyone it was her last, repeatedly forced to choose between the tour and her own health in a way most of her rivals never have to consider.

It's worth remembering, too, how rarely this specific version of a career gets told. Injuries end careers all the time, and so, eventually, does age. Collins' story is neither of those — it's a talented player whose body kept negotiating with her ambitions on its own terms, at 25, at 28, at 32, forcing a season-by-season renegotiation of what was even possible. Whatever Danielle Collins' career ends up being remembered for, it was never short of talent. It was only ever short of time.
