Top jockey Hollie Doyle shares her thoughts on a busy Saturday of racing action in her exclusive blog. Archie Watson sends two promising young horses to Thirsk, where Doyle will be in action, starting with the debut of two-year-old Niewiadoma in the British EBF Fillies' Novice Stakes.

Doyle has been impressed with Niewiadoma's natural speed and lovely attitude in preparation for her first outing. However, the field is full of unknowns, including Karl Burke's expensive daughter of Blue Point, Bai Tong. Merlier, who has been progressive on the All-Weather, will be Doyle's ride in the Stirrup Bar For Deli-Style Dining Packages Handicap. He has earned an opening rating of 85 after winning at Newcastle and Wolverhampton.

Zavateri, the standard-setter, will face Albert Einstein in the Watership Down Stud Too Darn Hot Greenham Stakes at Newbury. Zavateri rounded off his juvenile campaign with a Group 1 win in Ireland and is the one to beat.

Doyle will ride Warm Spell in the Join Racing TV Today Handicap, who has been eased to a career-low mark. She expects him to go close, given his nice races in defeat for Mark Loughnane and his ability to go well fresh.

Doyle will also ride Idyllic in the Happy 21st Birthday Lily Watkinson Handicap for veteran trainer Wilf Storey, a course and distance winner who should enjoy similar conditions. Meanwhile, Solar Biricz will make his debut for Mark Walford in the Nick Simpson Cannot Be 60 Handicap, stepping up to six furlongs for the first time. The Group 3 Dubai Duty Free Stakes, also known as the Fred Darling, looks like an open renewal, with several fillies holding similar prospects. Doyle is convinced that Shadwell's Touleen is better than she showed in the Rockfel last autumn and will need to be to win this traditional Classic trial.

Urban Lion could achieve a notable success if he can add the Win Unique Experiences At OLBG Prizes Spring Cup Handicap to his win in the Lincoln. Doyle expects Simon and Ed Crisford's Shout to fare better than he did at Doncaster.

Finally, Doyle hopes to see old Al Aasy win the Dubai Duty Free Finest Surprise Stakes for Tom Marquand and William Haggas, as the nine-year-old loves the track and can keep Karl Burke's likely favourite Convergent on his toes.
