Lady Mariko is our pick on profile: she was fourth last time out just 15 days ago, has run over today's trip and going, and our 80 rating ranks her second of 11, though she's yet to win in her last six starts.
AI verdict

SR 73 is competitive — each-way claims if conditions suit on the day.

Lahan Kingman arrives in cracking nick, runner-up last time out, and she has finished second in three of her last five, with a fourth two starts back and another fourth three starts back. She has run over today's trip and is fresh enough after 19 days, but she's yet to win in that spell, and that remains the one concern.
AI verdict

SR 66 suggests ability but 17/2 reflects a stiff ask in this field.

Vishaka has a win four starts back, and she is fresh from a run just 13 days ago, having run over today's trip before. Our 81 rating tops the field of 11 against an official 70, but the main risk is a seventh last time out and a sliding run of finishes since that win.
AI verdict

SR 55 is modest for this company — needs everything to go right at 16/1.

Diamondinthedark showed she can be competitive with a third two starts back and a second four starts back, and she's fresh enough after 19 days, with experience of today's trip. Our rating of 73 sits above her official 70, though she's winless in her last five and was eighth last time out.

SR 67 suggests ability but 17/2 reflects a stiff ask in this field.

Happier arrives in sound form, third last time out and a winner two starts back, with three wins in her last six outings, and she has run over today's trip. Against that, she carries 135 lb from draw 10 after 30 days off, and our rating of 69 ranks her only eighth of eleven.

Leonie has been in and around it lately, a winner three starts back and two thirds before that, but she's been unplaced last time out and sixth two starts ago. Fit after 19 days, she has run over today's trip and going, though 135 lb from stall 9 and a seventh-ranked rating of 70 suggest a midfield finish.

SR 64 suggests ability but 14/1 reflects a stiff ask in this field.

Second last time out and a winner four starts back, Amelia's Joy has run over today's trip and going, but a seventh two starts back and 49 days off the track temper the case. She carries 135 lb from draw 3, and our rating of 72 ranks her sixth of 11.

SR 76 is competitive — each-way claims if conditions suit on the day.

Duskaura is fresh off a fifth last time out, 15 days ago, and has run over today's trip, but a sixth and an eighth before that show she's been short of winning form since a victory four starts back. Our rating of 72 sits above her official 68, though she carries 135 lb from draw 11.

SR 49 is modest for this company — needs everything to go right at 22/1.

Magna has tailed off since back-to-back wins five and six starts back, finishing a third, a seventh, a fourth, then a sixth last time out, and she returns after 51 days. She has run over today's trip and going, but 134 lb from stall 1 and a tenth-of-eleven ranking make her hard to fancy.

Nzuri arrives in cracking nick, a winner last time out and again two starts back, and she has run over today's trip and going, but 133 lb off a mark of 66 is a big ask. Our figures rank her last of eleven, with a modest speed rating of 56.

Winless in her last five, Jenny Jerome has been creeping closer with a third last time out and a fourth before that, and she's back quickly after seven days, and she has run over today's trip and going before. Ranked ninth of eleven on our figures, she's hard to fancy, though 127 lb off 60 gives her a little to work with.
AI verdict

SR 53 is modest for this company — needs everything to go right at 16/1.

Lady Mariko
Confidence: Speculative

Lady Mariko (SR 73, 10/3) leads the field on SR and carries top-weight of 9-12, but the market has backed her in 15% to shortest price in the race, signalling strong confidence. She holds a Course:W1P1 record at Kempton AW and her MarkMv:-4 means she is running off a mark 4lb lower than her last win — a meaningful advantage in a Class 5 sprint. The form string 606004 looks rough but the recent visor application combined with the drop in mark and strong market move into 10/3 suggests connections are targeting this race. At 11 runners she is a clear class edge at SR 73 and the weight burden, while real, is only 1lb over most of the shortlist. Each-way alternative: Magna. Main danger: Magna — Magna (SR 68, 6/1) is the Tony Carroll yard's confirmed number one with Rossa Ryan booked, has steamed in 27% in the market, carries a favourable 9-8, and boasts a remarkable Course:W1P7 record at Kempton — she handles this track better than any other runner in the field.

Case against 4 clamped
  • Form string 606004 shows six consecutive runs without a win, including a 0 (last place) two runs ago — the visor is first-time headgear change but connections have been firing blanks for months.
  • Amelia's Joy (SR 76) and Happier (SR 75) both post higher Speed Ratings than Lady Mariko (SR 73) and carry 3lb less weight — Lady Mariko is not actually the class edge at the weights.
  • Happier arrives on form 112413 — won twice in last five starts and is backed in 12% to 11/2, offering a more compelling recent winning profile versus Lady Mariko's current losing run of six.
  • Magna holds a dominant Course:W1P7 record at Kempton AW — eight career runs at this track against Lady Mariko's two — and has been backed in 27%, suggesting sharper course-specific fitness.
