Quick Take

Pre-match view

Context last updated 27 Sep 2026, 22:49 · Europe/Bucharest

Two players short of hard-court wins meet in the Jingshan first round, and the two serves decide the shape of it.

Jones wins 60.3% of first-serve points on hard (283/469) but averages 7.6 double faults per hard-court match (76 in 10); Kaji is 4-7 in her last 11. Kaji looks the likelier winner, and at 3.75 she is the one reviewed price worth backing. Jones at 1.29 is one to leave alone.

Context

Jones, 18 and ranked No. 133, enters Jingshan as the third seed, while Kaji, 31 and ranked No. 257, arrives unseeded against her in the first round; the 124-place ranking gap sets the pre-match baseline. The draw's top seed is world No. 93 Jessica Bouzas Maneiro, which underlines that this is a strong field for a 125-level event rather than a soft one. Seeding reflects entry ranking rather than current form on Chinese hard courts, so it frames the level of the fixture without settling how either player is playing this week.
- Jones is listed as the third seed, ranked No. 133, in the WTA 125 Jingshan main draw
- Kaji, ranked No. 257, is unseeded and drawn to face Jones in the first round on 28 September
- The top seed is Jessica Bouzas Maneiro, ranked No. 93

Jones is the higher-ranked player here, but her second serve is the part of her game that keeps opponents in rallies.
The 113 double faults in 15 tracked matches sit alongside a second-serve points-won rate of just 42.1% (236 of 560), so Jones is not only missing first serves but also losing most of the points that follow. Against a returner who can keep the ball in play, that is the clearest route into her service games, and it is the number most likely to shape how the sets are scored. It is an average over a small sample rather than a fixed rate for this match.
- 113 double faults across the 15 matches tracked in her recent record (7.5 per match)
- Second-serve points won: 42.1% (236 of 560) in the same 15-match sample
- First-serve points won in that sample: 61.9% (436 of 704), showing the gap between her two deliveries
Jones has been a slow starter on hard courts in this window, and her opening sets have run long rather than ending quickly.
She has averaged 5.2 games won against 6.0 lost in first sets across those 10 matches, with three of them going to a tiebreak, so the early part of her matches tends to be both competitive and drawn out. That is useful context for the start of this first round: Jones often gives her opponent a foothold before the match settles. The sample is only 10 matches, so it describes her recent hard-court run rather than a permanent pattern.
- First sets on hard: 2 wins, 8 losses across 10 completed matches (3 May – 22 September 2026)
- Opening sets average 5.2 games won and 6.0 games lost, 11.2 games in total
- Three of those 10 opening sets went to a tiebreak; four of the 10 matches featured a tiebreak at some stage
Jones reaches Jingshan having lost her Seoul opener 6-3 0-6 2-6 to qualifier Ye-Xin Ma, a match she led by a set before dropping the next two. That is her only completed match in more than a month, so it is the most recent on-court evidence of her level on hard courts going into the Jingshan first round. A single match is thin evidence of form, and the scoreline indicates a mid-match swing rather than a settled measure of her current level.
- Jones lost her Seoul opener 6-3 0-6 2-6 to Ye-Xin Ma
- Ma came through qualifying before beating Jones
- Jones's previous completed match was on 25 August
