Why Danielle Kelly matters in grappling
Danielle Kelly became one of the most visible athletes in the first wave of ONE Championship’s women’s submission-grappling division. Her run from a draw in ONE’s 2022 debut to the inaugural atomweight title in 2023 provides a compact study of back attacks, leg-entry awareness, and tactical adaptation against opponents from sambo, judo, and modern sport jiu-jitsu.
Kelly’s best work often begins when she can attach to an opponent’s hips during a turn. She uses that connection to climb toward the back, threaten the neck, or switch to a leg when the upper body becomes difficult to control. Against judoka Ayaka Miura, the challenge was surviving scarf-hold pressure and creating back exposure; against Mariia Molchanova, the opening came much earlier and led to a fast rear-naked choke. The contrast shows why the entry and opponent’s base matter as much as the finishing technique.
The two 2024 losses to Mayssa Bastos provide an important boundary on the analysis. Against a specialist with elite guard retention and positional timing, Kelly had fewer prolonged back-control opportunities, showing that her strongest route still depends on winning the transitional exchange first.

Training takeaways
Back attacks begin with hip connection. Practice following the opponent’s turn before reaching for the neck, especially against opponents who can explode out of loose control.
Kelly’s matches show the value of opponent-specific preparation: scarf-hold defense, sambo posture, and sport-BJJ guard exchanges create different routes to the same preferred position.
