Magda Linette produced a stunning upset over world number one Iga Świątek at Miami, the WTA Masters 1000 event on hard court in the first round, winning 1–6, 7–5, 6–3. Świątek, the overwhelming pre-match favourite at odds of 1.03, was broken down after losing the opening set decisively. Linette, an 12.25 outsider, clawed her way back into the match during the second set, converting her opportunities in a tight tiebreaker-style battle before running away with the third. The Polish domestic rivals' encounter saw Linette reverse the expected narrative entirely, claiming a career-defining victory that will reshape their head-to-head record and raise serious questions about Świątek's form heading into the season's key hardcourt swing.
