Alex Eala enters the 2026 US Open with something she did not have a year ago: genuine Top-20 status, a WTA 500 title, a Grand Slam fourth-round appearance and proven wins over elite opponents.
And now, at Flushing Meadows, she has another intriguing advantage: Toni Nadal is working with her during practice, with particular attention reportedly given to her serve. Philippine reports say Nadal joined Eala's New York training and provided strategic advice, while her serve was a specific focus.
That does not mean Toni Nadal has replaced Joan Bosch as Eala's coach. Bosch remains a central figure in her coaching team and has been described by Eala as her confidant.
Instead, Nadal's involvement is best understood as high-level coaching input and consultation, particularly valuable because of his experience developing Rafael Nadal's competitive mentality and because Eala came through the Rafa Nadal Academy.
Who Is Coaching Alex Eala?
Eala's development has been closely connected with the Rafa Nadal Academy in Mallorca, where she trained during her formative years. The WTA lists Joan Bosch as her coach and notes that she trains at the academy.
Toni Nadal's relationship with Eala goes back much further than this week's US Open preparation. Eala has previously spoken about the positive impact of having Toni involved with her team, describing his experience as something that can help her coaching structure.
The current New York situation is particularly interesting because Toni's expertise is being applied to one of the most important areas of Eala's game: the serve.
1. The Serve: Toni Nadal's Most Important Technical Target?
Eala's greatest weapon is arguably not her serve—it is what happens after the serve.
Her left-handed baseline game, early ball striking, movement and return ability allow her to put pressure on opponents. She has already demonstrated that she can dismantle the service games of some of the world's best players.
But the serve remains an area where additional improvement could dramatically increase her ceiling.
Tennis.com previously identified the need for Eala to add more bite to her serve, while recent reports from New York say Toni Nadal specifically worked with her on that shot.
What does a better serve give Eala?
A more effective serve could provide:
- More free points
- More first-ball opportunities
- Fewer defensive situations
- More protection against elite returners
- Easier holds at 30-30 and deuce
- More opportunities to attack with her forehand
- Less physical stress during long matches
The objective shouldn't necessarily be to transform Eala into a player who relies on huge aces.
The bigger goal is to make her serve difficult to attack.
That distinction is important.
2. The Eala Service Pattern Could Become Her New Weapon
The most interesting possibility is not simply increasing serve speed.
It is creating a repeatable service pattern.
For example:
Deuce court
Wide serve → open court → aggressive forehand
A left-handed player has excellent tactical opportunities on the deuce side. If Eala can consistently move an opponent outside the singles court with the serve, her first forehand can become the attacking shot.
Ad court
Body/T serve → weak return → first-ball attack
Against aggressive returners, a body serve can prevent them from taking the return early.
Variation
Wide → T → body → wide
The objective is to prevent opponents from sitting on one location.
This is where a coach with Toni Nadal's experience can potentially add value—not necessarily by rebuilding the entire motion, but by helping turn the serve into part of a larger point-construction system.
3. Eala Already Has the Return Game
This is what makes the serve improvement particularly exciting.
Eala doesn't need to become a completely different player.
Her return is already one of the foundations of her game.
At the 2025 Miami Open, she famously defeated elite opposition by attacking service games, including an extraordinary performance against Iga Świątek. Tennis.com noted that Eala repeatedly dismantled opponents' service games during that breakthrough run.
So imagine the combination:
Better serve + elite return + aggressive baseline game = much greater control of matches.
Instead of needing to break an opponent repeatedly to compensate for vulnerable service games, Eala could begin winning more matches through a balanced combination of holding and breaking.
4. Toni Nadal's Mental Philosophy Could Be Just as Important
The Toni Nadal effect isn't only about technique.
His coaching philosophy has historically emphasized:
- Discipline
- Competitive resilience
- Acceptance of difficult moments
- High-intensity practice
- Fighting for every point
- Maintaining concentration
- Not becoming emotionally overwhelmed by the occasion
That could be extremely important for Eala now.
She is no longer an unknown teenager entering a Grand Slam.
She is World No. 18 and one of the most recognizable emerging players in women's tennis. The WTA currently lists her at No. 18, with a 2026 record of 38–20 and one WTA singles title.
That creates a completely different psychological challenge.
Opponents now know her.
They prepare for her.
Fans expect her to win.
And the pressure is much greater.
5. Why 2026 Is Different for Eala
Eala's rise during 2026 has been extraordinary.
She reached the fourth round of Wimbledon, her deepest Grand Slam run to date, and defeated defending champion Iga Świątek along the way.
Then came Washington.
At the Mubadala DC Open, Eala defeated a remarkable series of opponents, including Qinwen Zheng, Leylah Fernandez, Elina Svitolina and Naomi Osaka before defeating Jessica Pegula in the final to claim her first WTA 500 title.
The result pushed her into the world's Top 20.
She now arrives in New York as a completely different player from the one who stunned Clara Tauson in the first round of the 2025 US Open.
The official US Open site notes that Eala's 2025 victory was the first Grand Slam main-draw singles win by a Filipino player in the Open Era.
6. Can Alex Eala Win the 2026 US Open?
Yes—but winning the entire tournament would still be a major upset.
There is an important distinction between:
Can she win the US Open?
and
Should she be considered one of the favorites?
Right now, I would say she is a dangerous contender, not the favorite.
The women's draw remains extremely difficult, with established Grand Slam champions and elite Top-10 players capable of producing exceptional two-week runs.
But Eala has already demonstrated something essential:
She can beat elite players.
That changes the conversation.
A player who has defeated major champions and reached the fourth round at Wimbledon cannot be dismissed as a dark-horse novelty anymore.
7. What Would Eala Need to Do to Reach the Final?
I would identify five critical requirements.
1. Protect the serve
This is the biggest one.
If Eala can raise her service effectiveness—even without dramatically increasing raw speed—she becomes substantially harder to beat.
2. Keep attacking second serves
Her return game can create immediate pressure.
She shouldn't allow opponents to comfortably start points from neutral positions.
3. Maintain aggressive court positioning
Eala's ability to take the ball early is one of the reasons her game can trouble powerful players.
She should avoid being pushed several meters behind the baseline.
4. Survive the physical demands
A Grand Slam is different from winning a single WTA tournament.
Potentially seven matches means:
serve + movement + recovery + nutrition + sleep + physical durability
all become part of the equation.
5. Control the emotional moments
This may ultimately determine how far she goes.
The difference between the fourth round, semifinal and final often isn't pure shot-making.
It's what happens at:
4-4, 30-30.
5-5, 30-30.
Break point.
Set point.
Third-set pressure.
That's where experience and mental discipline become incredibly valuable.
8. The Toni Nadal Factor
The most interesting aspect of Toni Nadal's involvement isn't that he suddenly possesses a magic formula that will make Eala unbeatable.
It is that he can potentially help sharpen an already very good player.
Eala already has:
Left-handedness
↓
Aggressive baseline game
↓
Excellent return ability
↓
Early ball striking
↓
Top-level movement
↓
Experience against elite opponents
Add:
More effective serve
+
Better service patterns
+
Tactical discipline
+
Grand Slam mentality
and the ceiling rises considerably.
9. My US Open Prediction for Alex Eala
If Eala plays at the level she showed at Wimbledon and Washington, a second week is realistic.
Conservative expectation:
Round 3–4
Strong tournament:
Quarterfinal
Breakthrough tournament:
Semifinal
Dream scenario:
Final or champion
Winning seven matches at a Grand Slam is extraordinarily difficult, so predicting Eala to win the title would be aggressive.
But predicting that she cannot win it would be equally difficult to justify after what she has accomplished in 2026.
The biggest question may ultimately be:
Can Eala turn her serve from a potential weakness into a reliable first-strike weapon?
If Toni Nadal and Eala's existing team can make that improvement without disrupting the strengths that made her successful, her chances of beating the very best players increase dramatically.
Final Verdict: Can Eala Win the US Open?
Yes.
But I would frame it as possible rather than probable.
Eala is now good enough to beat Top-10 players. She has already won a WTA 500 title, reached the Wimbledon fourth round and climbed to World No. 18.
The next evolution is consistency.
The return is there.
The baseline game is there.
The confidence is there.
The experience is growing.
Now comes the serve.
And if the Toni Nadal input helps turn that serve into a more reliable weapon, the Philippines may have a genuine US Open second-week—and potentially title—contender in Alexandra Eala.
Her first-round match is against American Mary Stoiana, with the match scheduled for September 2 at the US Open.
