Just one year after making history as a 17-year-old in Guadalajara, Mexico, South Bay prodigy Iva Jovic is a WTA champion once again.

The 18-year-old Torrance native successfully defended her Guadalajara Open title on Saturday, defeating Peyton Stearns 6-4, 6-2 in an all-American final to capture the second WTA singles title of her career.

Bringing the same relentless SoCal grit to Mexico that fueled her junior days, Jovic put on a serving masterclass under pressure in the final. She won 70 percent of her service points, did not face a single break point, and converted three of her five break opportunities in a dominant 86 minute victory over Stearns.

The win made Jovic the first player to successfully defend the Guadalajara title since the tournament’s inception in 2021, earning her a $185,500 winner’s check and propelling her to a career-high world No. 13 in the PIF WTA Rankings.

“I’m just happy with the improvements I’ve made throughout the year,” Jovic said after the final. “I think I’ve shown that I’m a more complete and better player than I was this time around last year.”

Looking ahead at her rapid rise, Jovic knows maintaining that momentum takes relentless consistency.

“The age will obviously go up, but the ranking hopefully goes down,” Jovic said with a smile. “If you want to be in the Top 20, Top 10, you need to be doing very well every single week, and I’ve been doing a good job of that.”

A Flawless Week in Mexico

Jovic’s title defense was nothing short of commanding. Arriving in “La Perla Tapatía” as the No. 2 seed, she didn’t drop a single set all week at the Pan American Tennis Center’s Skarch Stadium, stringing together victories over Turkey’s Zeynep Sonmez, Poland’s Magdalena Frech, and Spain’s Cristina Bucsa on her way to the final. The championship extended her undefeated career record in Guadalajara to 9-0.

Her semifinal performance against Bucsa proved pivotal. Capitalizing on 50 percent of her break opportunities (4-for-8), Jovic fended off 11 of 12 break points against the sixth seed. After building an early 3-0 lead, Jovic faced heavy pressure as Bucsa fought back and created a 0-40 opening with Jovic serving at 5-4, but she held her nerve to save all three break points before breaking Bucsa in the very next game to take the opening set. Jovic carried that momentum into the second, reeling off five straight games and saving all six break points she faced to close out a 6-4, 6-1 victory.

“Last year was one of the best moments of my career. It was a crazy week and definitely a little unexpected to lift the title,” Jovic noted after her semifinal. “It meant so much to me. There’s so much support from the fans here, and that motivated me to keep winning and playing my best tennis. I love playing here.”

Building Momentum from New York

Jovic arrived in Mexico directly from the biggest US Open run of her young career.

Seeded No. 14 at Flushing Meadows, she advanced to the fourth round of her home Grand Slam for the first time. It was also her first time competing as a seeded player at her home major.

She opened her tournament with a 7-5, 6-3 victory over Magdalena Frech, whom she would defeat again two weeks later in Mexico, advancing to the second round at the US Open for the third consecutive year.

Her fortnight was highlighted by an electrifying, three-hour third-round battle inside Arthur Ashe Stadium against fellow rising star Alexandra Eala. Overcoming a 4-2 deficit in the third set, Jovic fired 44 winners to claim a 7-5, 3-6, 7-5 marathon victory.

“That felt like a marathon,” Jovic reflected following the win. “I felt like I lost my sanity five times over to win that match. But it is really worth it for this feeling.”

Although her run in Flushing Meadows ended against 2023 champion Coco Gauff, the momentum carried seamlessly into Guadalajara.

The SoCal Pipeline to Tour Success

When Jovic won her first WTA title in Guadalajara in September 2025 against Colombia’s Emiliana Arango, she became the youngest American to win a WTA Tour-level title since Coco Gauff in 2021 and the youngest WTA 500 champion since Martina Hingis in 1998. Her victory also propelled her 37 spots up the rankings to No. 36. A year later, her steady climb continues—built on a foundation developed on Southern California courts.

Former world No. 1 Kim Clijsters recently praised Jovic’s aggressive baseline identity, noting her ability to step inside the court, dictate play from high positions, and generate her own power. That attacking style was refined at the Jack Kramer Club in Rolling Hills Estates and through the competitive USTA Southern California section where Jovic grew up competing.

“I grew up in Southern California; our section is incredibly strong, so I was very fortunate with that,” Jovic said. “We have a lot of great tournaments, a lot of great players. Playing those USTA tournaments really was the first step for me and then moving on to the ITFs, and then onto the Pro Circuit.”

Jovic grew up training at the historic Jack Kramer Club in Rolling Hills Estates. One of her earliest breakthroughs came at the USTA Easter Bowl, where she won the 14s title as a 13-year-old. That same year, she won the USTA Southern California Girls’ 18s Junior Sectionals title.

One of her earliest breakthroughs came at the USTA Easter Bowl, where she won the 14s title as a 13-year-old. That same year, she won the USTA Southern California Girls’ 18s Junior Sectionals title, an achievement she still considers one of her most special USTA experiences.

“The [USTA Southern California] Junior Sectionals was super special for me. I won that one in the 18s, and that is just a very historic part of Southern California,” she said.

Her progression accelerated quickly. At 14, Jovic reached the final of a $15,000 professional event on her home courts at the Jack Kramer Club. At 16, she swept the singles and doubles titles at the USTA Billie Jean King Girls’ 18s National Championships at the Barnes Tennis Center in San Diego, earning her Grand Slam main draw debut at the 2024 US Open.

Jovic made her US Open debut at just 16 years old and defeated Magda Linette in the first round, becoming the youngest American to win a women’s singles match at the US Open since 2000.

Now boasting an Australian Open quarterfinal appearance, back-to-back Guadalajara titles, and a Top 15 ranking, Jovic’s progression reflects the step-by-step development she now encourages in the next generation. For the young Southern California players following a similar path, her message remains simple.

“Take it one step at a time,” Jovic encouraged. “You’re not as far as you think you are. Everyone needs to start at the USTA, and then you move onto the ITF, so just take it one step at a time and try to get better with every match, every day.”

Her latest championship adds another chapter to that journey as she turns her attention to the final stretch of the 2026 season, beginning with the China Open in Beijing.
