28,000gns yearling; by Kodi Bear; dam 6f AW winner (RPR 72), sister to Group-placed 1m 2yo winner Dark Rose Angel, half-sister to 7f-1m2f winner Dark Company; stable had a first-time-out 2yo winner over C&D this month; well worth a market check.

11,000gns foal, £21,000 yearling; Sergei Prokofiev half-sister to 5.7f 2yo winner Reality Queen (RPR 60); dam prolific 5f/6f winner (including 2yo; 84), half-sister to Group-placed 5f-7f winner May Sonic; bred to be sharp and is in good hands; plausible newcomer.

Built on her debut outing when third of nine over C&D (good to soft) on her second start but well held at Thirsk (5f, good) 11 days ago; each-way claims back here in this lower grade.

Shaped nicely on debut when second at Beverley (5f, good to soft) but then folded tamely when joint-favourite at Southwell (5f, AW); has obvious claims on that first run and this return to turf could be in her favour.

Last at Southwell (5f) and Ripon (6f); has shown some speed and her stable won a division of this race in 2024, but she needs cheekpieces to make a big difference.

Showed something to build on when 7l fourth of eight over C&D (good to firm; 25-1) two weeks ago, briefly looking a threat; open to improvement and could be the stable's first string judged on jockey bookings.
