Introduction
A six-runner dash over 275 metres at Doncaster in an Open Race grade — and our prediction models can't quite agree on who should be favourite, which is exactly the kind of race I love getting my teeth into. The Composite Rating model has Jays Pippin narrowly ahead with a rating of 40, with Java Kate breathing down her neck at 39. Flip to the Form Rating model, though, and it's a completely different story — Reign Of Power storms to the top on 74, with Mossend Chip second and Jays Pippin third. That's a genuine clash worth exploring.
Doncaster over 275 metres is a sharp, unforgiving test. There's almost no time to recover from a bad break or a first-bend incident — positions are made and often settled within the first three seconds. It rewards early pace, clean beginnings, and dogs with the composure to navigate what can be a notoriously congested early bend. This is a competitive little sprint.

What To Expect
The trap bias data from the last 90 days at Doncaster tells an interesting story. Trap 3 leads the way with a 22.7% win rate from 620 races — that's a meaningful edge over the field. Trap 6 follows at 21.3%, with Trap 1 at 20.8%. At the bottom sit Traps 4 and 5, at 17.2% and 17.9% respectively. That's a significant disadvantage for Reign Of Power in Trap 4 and Mossend Chip in Trap 5.
Our composite model's top pick, Jays Pippin, draws in Trap 2 — a solid 19.6% strike rate, comfortably mid-table. It won't deliver a natural rails advantage, but it's far from a death draw either. The data profile here leans toward dogs drawn in the low-to-middle traps, and that broadly supports the composite model's top two.

Form
Matching Jamas is stepping up from D2 company into Open Race grade, which is a significant jump and not one I'd make too much of for now. That said, she did win here over 275m on 1 June in a time of 17.28s, which shows she's capable of getting competitive at this venue and distance. Her most recent effort on 8 June saw her finish fifth in D2 with a slow away and mid-rail release — not a form line to inspire confidence stepping into tougher territory.
Jays Pippin is the one who catches the eye on raw ratings, but the form profile requires a little context. Her last two runs at Doncaster were both over 450 metres, and she finished fifth and sixth in those — admittedly with notes like "badly bumped at one" and "missed break, crowded two." Before that, she was a model of consistency at Hove over 285m, running four consecutive second-place finishes at Open grade. She was running against good animals there, and her best time of 16.02 seconds speaks volumes about raw speed. The switch back to a short sprint trip is the key question, but her Hove form over comparable distances gives strong reason to trust the model's faith in her.
Seven Brent has drifted a long way from her last competitive run — there are significant gaps in the form, including a five-month absence between July 2025 and January 2026. The most recent outing at Valley on 5 July was modest, finishing fourth with interference noted at the one-and-a-half mark. Most of her career form is over Monmore's 264m, which is a similar distance but a very different track. She did win at Monmore in D4 on 28 January, showing she can produce when things go right, but this Open grade field looks a step too far.
Reign Of Power is the one the form model loves, and I can see why. Strip away the 275m debut at Doncaster last Saturday — where she finished third after being crowded at one and bumped on the run-in — and you have a greyhound in excellent recent form. Two wins at Hove over 500m in May and June, both at A1/A2 grade, with race comments showing "quick away, railed, all-led" and "early pace, railed, soon led." The concern is the distance switch from 500 metres to 275 metres. Reign Of Power is built as a front-running stayer — can she recapture that same intensity over the bare minimum? Last week suggests she can compete, but the bump and crowding cost her.
Mossend Chip hasn't raced here before and comes from Sunderland and Star Pelaw tracks, which makes form comparison difficult. There's a void run in the recent record and she's stepping down from 450 metres. Her speed rating of 80/100 is noteworthy — there's genuine ability in there — but the first-bend rating of 0/100 is alarming for a 275-metre sprint where you cannot afford to be slow into the turn. This feels like a watching brief.
Java Kate, trained alongside Jays Pippin by R Fletcher, has her two most recent runs here at Doncaster over 275m — finishing fifth on both occasions. However, the race comments tell a more sympathetic story: "challenged and badly blocked at one" on 11 July, and "crowded from one to two and on the run-in" on 4 July. She's been desperately unlucky. Her First Bend Rating of 84/100 suggests she's actually a smart beginner, and the form at Doncaster over this exact trip, when unimpeded, looks potentially much better than those finishing positions suggest.

Run Style
This is where the race becomes genuinely fascinating. My reading of the pace profiles points to a race with a chaotic early bend at the very least.
Jays Pippin is flagged as a Fader — Early 100/100, Closing 0/100. In plain English, this dog is electric out of the traps but tends to get caught late. Over 275 metres, that's arguably a feature rather than a flaw: if you can blaze to the bend and clear the traffic, there's barely enough track left for rivals to reel you in.
Java Kate shares the same pace profile — Early 83/100, Closing 0/100 — and she's trained by the same handler. Two early-pace dogs from adjacent traps could be a recipe for carnage at the first bend. Java Kate's run comments on both recent Doncaster starts confirm exactly that concern. She keeps running into trouble precisely because she's up with the pace.
Reign Of Power is the opposite — rated as a Closer, Early 17/100, Closing 100/100. At 500 metres, that's a winning formula. Over 275 metres, that late run may simply run out of real estate. Mossend Chip also profiles as a Closer with an early rating of 0/100 — she may spend this race watching everyone else disappear into the distance.
Expect a fast, messy opening few seconds, with Jays Pippin and Java Kate both trying to establish position from adjacent traps. Traffic dangers are high.

Speed
*seconds per 10 metres — lower is faster
The speed picture is dominated by one horse in the room: Jays Pippin. A Speed Rating of 100/100 — the maximum our model can award — is extraordinary, and it's backed up by real times. Her best of 16.02 seconds at Hove over 285m represents genuinely elite raw pace for this level. Her last recorded time of 16.08 seconds is almost as good. It's worth noting that these times come over 285 metres at Hove rather than Doncaster's 275m, so direct comparison requires a pinch of salt, but the underlying speed is unquestionable.
The Sec/10m column is broadly illustrative — note that Mossend Chip's figure of 0.37 looks anomalous and likely reflects a timing discrepancy with her best time recorded over 261m at Sunderland rather than a comparable sprint. Don't read too much into that specific number in isolation. What it does confirm is that Reign Of Power (0.63) and Seven Brent (0.64) are operating at a slower pace profile, consistent with dogs who are either stayers dropping in trip or modest-grade sprinters.
Java Kate's last time of 17.98 seconds — versus a best of 17.51 — reflects those two troubled recent Doncaster runs, where she was badly blocked and crowded both times. Strip away the interference and there's a more competitive greyhound lurking. Her First Bend Rating of 84/100 confirms she does actually break quickly; the times just don't show it yet on this track.

How The Race Might Unfold
My expectation is a genuinely rapid opening ten metres. Jays Pippin, with that 100/100 early pace rating, should be quickest from Trap 2 — and if she avoids being carried wide by Java Kate in Trap 6 making her usual early move, she could have the rail and clear daylight before the bend.
Java Kate will be fast enough to be at Jays Pippin's quarters approaching the bend, but with six dogs converging from both sides, the inside rails are going to be a battleground. Reign Of Power, despite showing early pace in her stayer's profile, is rated 17/100 for early speed at this trip — she'll likely be a length or two off the pace going into the bend, which at 275 metres means she's already chasing.
Matching Jamas from Trap 1 has the rails draw and showed she could lead at this venue and distance as recently as 1 June. If Jays Pippin misses her break even fractionally, Matching Jamas could sneak through on the inside.
Seven Brent in the advantageous Trap 3 will look for a clear run through the middle — she needs to avoid the inevitable early carnage. Mossend Chip from Trap 5, with zero early pace, may find herself shuffled back on the outside with nowhere to go.
My vision of this race: Jays Pippin leads into the bend, Java Kate causes interference trying to challenge, and the result is decided in the first three seconds.

Final Conclusions
Aligning with our composite model, Jays Pippin is my selection. The Speed Rating of 100/100, the First Bend Rating of 94/100, and the consistent form over comparable distances at Hove all paint the picture of a genuine-class sprinter. Yes, the last two runs over 450m at Doncaster were poor — but read the race comments and the excuses are legitimate. Stepping back to 275m, her natural trip, I expect a very different performance.
The main danger, in my view, is not Reign Of Power — despite the form model's enthusiasm. A horse-for-courses stayer stepping down to a sprint trip, drawn in a low-percentage trap, classified as a pure Closer — the stars don't align sufficiently. My danger is Java Kate. Same trainer as the selection, proven early pace, drawn wide in Trap 6 which can actually help her avoid the inner chaos. If she gets a clean run — and that's the caveat — she's capable of troubling the selection.
In terms of fair odds: Jays Pippin looks like a 6/4 chance, Java Kate around 9/4, and Reign Of Power available at 4/1 for those who trust the form model's reading.
THE VERDICT: Jays Pippin has the pace, the trip, and the class to lead this field from the front and hold on — back her to confirm it.
