When Zach Heinzerling received a call about potentially filming a documentary about tennis legend Rafael Nadal, he quickly said yes — three times.
Do you speak Spanish? Yes.
Do you like tennis? Yes.
Do you want to film Rafa on potentially his last season? Yes.
The four-part Netflix docuseries by Mr. Heinzerling follows Nadal’s comeback attempt, beginning in 2024 at age 37. The comeback is paired with archival footage of his introduction to tennis as a child to his rapid rise as a tennis star, winning his first French Open at age 19.
But the series also reveals Nadal’s vulnerable side, including his struggle with anxiety and his debilitating injuries.
Circuit Arts screened the first episode of Rafa on Saturday, followed by a discussion with Mr. Heinzerling, a seasonal Vineyarder. During the talkback, Mr. Heinzerling reflected on the filming process, his relationship with Nadal and what makes him different from other elite athletes.
When Nadal does something he does it 100 per cent, “consequences and all,” said Mr. Heinzerling.
That was the case for most of the legendary tennis player’s career. He went all in on matches despite debilitating pain in his foot caused by a genetic deformity. During his career he won 22 Grand Slam men’s singles titles, including a record 14 French Open titles, earning him the nickname “King of Clay.”
Nadal also went all in with his involvement in the documentary, Mr. Heinzerling said. The series features extensive interviews with Nadal, his family and his coaches, and glimpses of private, emotional moments throughout his final season.
“I feel like we’ve kind of become accustomed to this commercialization of the athlete documentary, where the athlete, as producer, sort of takes the reins and presents a version of themselves that is absent of any vulnerability,” Mr. Heinzerling told the Gazette before the screening.
Working with Nadal felt different, Mr. Heinzerling said. The tennis star trusted Mr. Heinzerling and the documentary crew to tell the story of his career without trying to manipulate the narrative himself. That meant, at times, appearing exposed and vulnerable.
Maybe that’s naivete, Mr. Heinzerling said, and maybe it’s trust. Either way, it’s an honesty that Mr. Heinzerling found surprising and refreshing.
“The pieces of his life…that might seem sad or heartbreaking were the things that people needed to see, so that you would see the sort of sacrifice that athletes make to be at the very top,” he said.
The documentary begins with Nadal’s retirement announcement. It then flashes back to a year earlier, when he is attempting a tennis comeback after a debilitating hip injury that took him out for a year. After only a week of competition, Nadal re-injured his hip during a match. Mr. Heinzerling was in the car with him afterwards, filming the injured tennis giant on the verge of tears.
“When you witness that kind of vulnerability, it creates a bond with you and the subject,” Mr. Heinzerling said after the screening. “So because I had witnessed that, it sort of became a bit of a basis for a building of a relationship.”
Nadal continued with his comeback after the injury, even amid pressure from his family and coaches to retire. It became the central question of the series: Why can’t Nadal stop?
“Why can’t he stop brings you to the past, where each episode becomes kind of an answer to that question,” said Mr. Heinzerling.
The first episode focuses on the foot deformity that caused Nadal to have incurable pain from very early on in his promising career.
“It’s a blessing and a curse,” said Mr. Heinzerling. “It is sort of the reason why he has this internal drive to never give up, because he always feels as if any match will be his last.”
The second episode follows Nadal’s early tennis education, including the demanding and disciplined relationship with his coach and uncle, Toni Nadal. The third explores Nadal’s routines, such as tucking his hair or pulling at his clothes before serving the ball, which helped him cope with the immense pressure he felt in his career.
“I think there’s a softness about Rafa exposed in that episode that makes him…more sympathetic, but also just more human,” said Mr. Heinzerling.
The series also explores Nadal’s rivalries with tennis legends Roger Federer and Novak Djokovic, which help shape the narrative of who Nadal is as a tennis player. Against the uber-confident Djokovic, Nadal appeared modest and insecure. Against the graceful, ballet-like style of Federer, Nadal was a warrior-like personality, there to outlast his opponent.
“Federer walks on water, he’s the guy who has the most beautiful one-handed backhand. You can’t imitate Federer, you could never be Federer,” said Mr. Heinzerling. “Rafa, though, is the eternal underdog who won based on grit. You can’t be Rafa, but you can try.”
Mr. Heinzerling edited the series last summer while staying on the Vineyard. He’s been coming to the Island with his wife, a longtime seasonal Vineyarder, for almost a decade.
Mr. Heinzerling grew up playing tennis with his father, a former D1 tennis player. Even with solid strokes and lots of potential, Mr. Heinzerling is inconsistent, he said.
But Nadal is evidence of the power of perseverance and determination, those cliches that coaches use to inspire their athletes, said Mr. Heinzerling.
“Rafa can overcome obstacles and win…with exertion and determination, the things that we can use in our everyday existence,” said Mr. Heinzerling. “His mantra is just try to get better at it. Anything you’re doing, try to get better at it each day. Like, today, I was building a chicken coop.”
The chicken coop, located Mr. Heinzerling’s house in Chilmark, is actually for his family’s ducklings. Ducklings are more fun than chicks because they follow you around, he said. His seven-year-old daughter recently brought one to the West Tisbury farmers’ market and was the center of attention.
Mr. Heinzerling is not great at building chicken coops, he admitted.
“I could either just not do it and ask somebody else who’s better at it, or I could try to get better at it,” he said. “And Rafa inspired me.”
