The Mubadala DC Open semifinals feature some great matchups on Saturday, but the headliner may very well be this one between Naomi Osaka and Alexandra Eala.
Osaka needs no introduction as a four-time Grand Slam champion, while Eala is quickly becoming a household name as she continues to make waves this summer. After defeating Elina Svitolina in the quarterfinals, Eala now has six wins against top-10 opponents in 2026, four of which have come over the past two months.
Can the 21-year-old Filipino player pull off another upset? Or will Osaka take care of business on her best surface?
Below, we’ll break down our Naomi Osaka vs. Alexandra Eala prediction, including recent form, match analysis, and a PrizePicks pick. The match is slated to start at approximately 3:30 p.m. ET on Tennis Channel.

How to Watch: Tennis Channel
Alexandra Eala entered this tournament coming off an excellent grass season, winning a WTA 125 title in Birmingham and then reaching the fourth round at Wimbledon. She had previously never advanced past the second round of any major.
Therefore, we shouldn’t be surprised by Eala’s impressive run to the semifinals, highlighted by victories over Zheng Qinwen, defending Washington champion Leylah Fernandez, and Elina Svitolina. The fact that she bested Svitolina in straight sets is particularly notable.
On the other hand, Naomi Osaka ran into some trouble in the quarterfinals after dropping the opening set to world No. 71 Elisabetta Cocciaretto, but she ultimately prevailed with a 4-6, 6-4, 6-3 victory. Considering how well Eala has been playing, Osaka will likely need to raise her level if she’s to advance.
Still, Osaka entered this event with plenty of confidence herself after going 15-5 across the clay and grass swings. This included career-best results at both the French Open (fourth round) and Wimbledon (quarterfinals).
Now playing on her best surface, Osaka may only get stronger as she gears up for the US Open this summer. She owns a 67.4% career win rate on hard courts, and all seven of her tour-level titles have come on this surface.
Additionally, while Eala has found surprising success against top-10 players this season, she’s actually 6-9 when we expand out to top-20 opponents, so it’s not like she hasn’t had her struggles versus quality competition.
Ultimately, Osaka is the rightful favorite, particularly on hard courts. However, Eala’s recent form can’t be entirely ignored, and it’s unlikely she goes away quietly.
According to Tennis Abstract’s Elo ratings, Osaka projects for a 62.5% win probability over Eala.
