In the week of 13 April 2026, Tagger jumped 20 ranking places — from No. 117 to No. 97 — to become the youngest player in the WTA top 100 and the first player born in 2008 to reach it. The surge came from her first WTA 500 quarterfinal, on home soil in Linz, where she beat Paula Badosa and then Liudmila Samsonova 6-2, 7-6(11) — her first win over a top-30 opponent, sealed in one of the longest tiebreaks of the 2026 season.

The rise had been building for months. Ranked outside the top 700 in January 2025, she won the junior French Open in June, reached a tour-level final in Jiujiang on her WTA main-draw debut in the autumn, and added a WTA 125 final in Mumbai in February 2026. Working since her early teens with Francesca Schiavone — the 2010 Roland-Garros champion and a fellow one-handed-backhand player — she has climbed to a career-high No. 74 within thirteen months of her first ITF title.
