Alexandra Eala of the Philippines hits a return shot during the Wimbledon Tennis Championship.

Eala-mania will be in full force at Louis Armstrong Stadium on Tuesday night as Alexandra Eala faces Mary Stoiana in one of the day's final first-round matches.

Eala has quickly become one of the most popular players in the sport, and she comes into the US Open with added confidence after winning her first tour-level title in Washington this summer. The 21-year-old also advanced to the round of 16 at Wimbledon, easily her best result at a major. Could Eala go even farther at this year’s US Open?

Below, we’ll break down our Mary Stoiana vs. Alexandra Eala prediction, including recent form, match analysis, and a PrizePicks pick. The match is slated to start at approximately 8:40 p.m. ET on ESPN2.

Alexandra Eala has been packing stadiums all summer long, and that’s unlikely to change tonight in New York.

As a refresher, Eala’s strong play dates back to June. After plodding through a difficult stretch on clay, she regained her confidence during the grass swing, winning a WTA 125 title in Birmingham, reaching the semifinals in Berlin, and then advancing to the round of 16 at Wimbledon. 

Eala then brought that momentum stateside, claiming her first tour-level title in Washington. She’s up to a career-high 18th in the rankings after beginning 2026 ranked outside the top 50.  

Arguably the most impressive aspect of her recent success is who she’s beaten along the way. Over the past three months, she’s earned top-15 wins over Elena Rybakina, Elina Svitolina (twice), Iga Swiatek, Naomi Osaka, and Jessica Pegula. 

Although Eala followed her Washington title with earlier exits in both Toronto and Cincinnati, her recent losses came against Belinda Bencic and Amanda Anisimova, a pair of players currently ranked inside the top 12. The added rest ahead of the US Open could also be a positive after playing so many matches this summer, too.

Tonight, Eala will face qualifier Mary Stoiana, a player competing in her first major main draw.

This is a significant step up in competition for the 23-year-old Stoiana, who’s played almost exclusively in low-level tournaments. In fact, Eala will be her first opponent ranked inside the top 50 all year, let alone the top 20.

Despite being American, Stoiana won’t enjoy any sort of home-court advantage against the popular Eala either. 

In all, given Stoiana’s lack of experience playing on the big stage against top-flight competition, she could have a difficult time keeping up with an in-form Eala.
