Janice Tjen’s Career Finals (2024–2026) — Results, Opponents, Rankings and Chennai Open Title Defense.
In June 2024, Janice Tjen was winning $15,000 ITF tournaments in Monastir, Tunisia. Her WTA ranking was initially unlisted, and by the time she collected her third title that month, she was still outside the world’s top 1,000.
Less than two and a half years later, the Indonesian is preparing to defend her first WTA Tour singles title.
On Saturday, November 7, Tjen defeated American Robin Montgomery 6-3, 6-4 in the Chennai Open semifinals, setting up Sunday’s championship match against Magda Linette of Poland.
The victory places Tjen within one match of consecutive Chennai titles, an achievement that would have seemed distant when she began collecting professional trophies in 2024.
Her record in completed professional singles finals is already impressive: 15 victories and four defeats across 19 championship matches.

Those finals tell the story of a remarkable climb through the rankings, a sequence of titles that few players could hope to match, and three consecutive defeats that preceded her biggest successes.
June 2024: Three Finals in Monastir and Three Titles
Tjen’s first three professional singles titles came in June 2024 at the ITF W15 tournaments in Monastir.
She defeated Lithuania’s Patricija Paukštytė 6-1, 7-6(1), Belarusian Anna Kubareva 6-2, 6-3 and France’s Marine Szostak 6-1, 6-0.
The final against Szostak came with Tjen ranked world No. 1,046. Her opponent was No. 820.
The numbers illustrate just how far removed those early victories were from the WTA Tour.
Yet Tjen had already established a useful habit: when she reached a final, she usually won it.
Her next championship match came in August 2024 in Wanfercée-Baulet, Belgium.
Ranked No. 716, she defeated Luxembourg’s Marie Weckerle, then No. 564, 6-2, 6-2 to claim her fourth professional singles title.
Unlike the Monastir victories, which came on hard courts, this triumph was achieved on clay.
Seven Consecutive Finals Without a Defeat
Tjen continued winning finals throughout the remainder of 2024.
In November, she claimed another clay-court title at the ITF W15 event in Antalya, Turkey, defeating Canada’s Nadia Lagaev 6-1, 6-2.
She then traveled to New Zealand, where she added two more trophies in December.
At the W15 tournament in Wellington, Tjen defeated Japan’s Shiho Akita 6-4, 6-4.
A week later, at the higher-level W35 event in Tauranga, she beat another Japanese opponent, Hiromi Abe, 6-2, 6-1.
The Tauranga victory was particularly encouraging. Tjen was ranked No. 521 and Abe No. 498, making it another success against a higher-ranked opponent.
By the end of 2024, Tjen had contested seven professional singles finals and won every one of them.
She had also climbed from outside the rankings to the vicinity of the top 500.
Her first defeat in a final would not come until the following April.
April 2025: The First Final Defeat
Tjen entered the ITF W35 final in Goyang, South Korea, ranked world No. 371.
Her opponent was Japan’s Rina Saigo, then No. 407.
Tjen took the opening set, but Saigo recovered to win 2-6, 6-4, 6-1, ending the Indonesian’s perfect record in championship matches.
After seven consecutive victories, Tjen had finally lost a final.
What followed over the next two months was extraordinary.
Six ITF Titles in Seven Weeks
Between May and June 2025, Tjen won six ITF singles titles in just seven weeks.
She began by returning to Goyang, the same city where she had lost her first professional final.
This time, ranked No. 372, she defeated China’s Lin Zhu 6-4, 6-1.
Another title followed in Andong, South Korea, where she beat Ye Xin Ma 6-4, 6-2.
Then came four victories in China and Taiwan.
The Taipei final provided the toughest examination of that remarkable sequence.
Facing Japan’s Momoko Kobori, Tjen lost the opening set 4-6 before recovering to win 6-1, 6-2.
By then, her ranking had risen to No. 210.
At the beginning of May, she had been outside the top 300.
Six titles later, the top 200 was within reach.
But moving into stronger tournaments meant facing stronger opposition, and the next three finals would all end in defeat.
Three Straight Final Defeats as the Opposition Gets Stronger
In July 2025, Tjen reached the ITF W75 final in Lexington, Kentucky.
Ranked No. 195, she faced China’s Xiyu Wang, then No. 158.
Wang won 3-6, 6-2, 6-4.
The following month, Tjen contested the ITF W100 final in Landisville, Pennsylvania, against Croatia’s Petra Marcinko.
The Croatian, ranked No. 134, prevailed 7-6(4), 3-6, 6-4 after two hours and 29 minutes.
Those two defeats came against higher-ranked opponents and at stronger ITF events than the tournaments Tjen had been dominating earlier in the summer.
September brought her first WTA Tour-level singles final.
At the Sao Paulo Open, the Indonesian was ranked No. 130 when she faced France’s Tiantsoa Sarah Rakotomanga Rajaonah, then No. 214.
The Frenchwoman won 6-3, 6-4 in one hour and 26 minutes.
It was Tjen’s third consecutive defeat in a final.
Her ITF successes had brought her rapidly up the rankings, but winning a championship match on the WTA Tour presented a different challenge.
She would not have to wait long for another opportunity.
October 2025: Two Finals and the Biggest Titles of Her Career
In October, Tjen traveled to China for the Jinan WTA 125 tournament.
Ranked No. 98, she reached the final against Hungary’s Anna Bondar, the world No. 90.
The Indonesian won 6-4, 4-6, 6-4 after two hours and 25 minutes, claiming her first WTA 125 singles title.
More importantly, the victory ended her run of three consecutive final defeats.
Her next championship match came at the Chennai Open.
Tjen arrived ranked No. 82 and faced Australia’s Kimberly Birrell, then No. 117, in the final.
She won 6-4, 6-3 in two hours, securing her first WTA Tour-level singles title.
The victory completed an astonishing transformation.
In June 2024, Tjen had been competing at the lowest professional tournament level, with no established WTA ranking.
By October 2025, she had won a WTA Tour title and risen to No. 82.
Her overall professional singles finals record now stood at 15 wins and four losses.
Janice Tjen’s Career Finals Record by Level
Of her 15 titles, 13 came on the ITF circuit, one at WTA 125 level and one on the WTA Tour.
Her second Chennai Open final, scheduled for Sunday, November 8, 2026, will be her 20th professional singles final and third at WTA Tour level.
Tjen Beats Robin Montgomery to Return to the Chennai Final
Tjen’s latest final appearance was secured with a straight-sets victory over American Robin Montgomery, ranked world No. 151.
The Indonesian top seed, ranked No. 75, started Saturday’s semifinal confidently, holding her opening service game before breaking Montgomery for a 3-1 lead.
After consolidating, Tjen broke again to move ahead 5-1.
Montgomery briefly threatened a comeback, breaking the Indonesian’s serve for 5-2 before holding to reduce the deficit to 5-3.
But Tjen responded by serving out the opening set 6-3.
The second set was considerably more competitive.
Both players held serve through the opening six games, with Tjen facing two break points while serving at 2-3.
She saved both to reach 3-3.
The decisive breakthrough came in the seventh game, when Tjen converted her fourth break-point opportunity to lead 4-3.
She consolidated for 5-3 before Montgomery held serve to keep the match alive.
Tjen then served out the contest 6-4, finishing on her first match point.
There was no extended celebration needed to explain the result: the defending champion was back in the Chennai final.

Magda Linette Is Tjen’s Final Obstacle on Sunday
Poland’s Magda Linette will face Janice Tjen in Sunday’s Chennai Open final.
Tjen has won the title before, but she has never successfully defended a WTA Tour singles championship.
Linette now has the opportunity to prevent that from happening.
Saturday’s semifinal showed how difficult Tjen can be to break down when her serve is working.
Montgomery managed just one break despite creating seven opportunities, and Tjen won nine of her ten service games.
Whether she can maintain that level against Linette will be one of Sunday’s important questions.
The final also carries a special significance for Chennai. With the tournament’s WTA 250 license expected to move to Manila in 2027, Sunday’s champion could be the last winner under the current arrangement.
Janice Tjen was the player who lifted the trophy in 2025. Magda Linette Linette now has one match to stop her from keeping it in 2026.
