It's all change at the top of Timeform's two-year-old rankings, with two new winners from last week finding a place in the top three, including the first 'TDN Rising Star' in this division of 2026.5. BLESSED VOYAGER (IRE)Bayside Boy (Ire) – Elysium (Ire), by Belardo (Ire)Timeform performance rating: 81The G1 Queen Elizabeth II Stakes hero Bayside Boy was represented by his first winner when Blessed Voyager edged to victory in the 5f maiden run at Newbury on Friday. Described by Timeform as “one of the better types in the line-up”, he was always doing enough to make a successful debut after being produced to lead a furlong out, albeit it might have been a different story had the runner-up, Harry Knows (Mehmas), not conceded first run after being squeezed out early on.The first two were separated by just a head at the line, with both running to a Timeform performance rating of 81, having pulled two lengths clear of the rest. Needless to say, Harry Knows will be one to follow in a similar event next time, while Blessed Voyager can likewise build on this for Ralph Beckett, who has made a fast start with his two-year-olds, having also sent out the Brocklesby second Dance A Jig (Naval Crown) with his only other runner in this division.An €80,000 purchase at Book 1 of the Goffs Orby Yearling Sale, Blessed Voyager is the second foal and first runner out of the G3 Weld Park Stakes scorer Elysium who, in turn, is out of the Listed Chesham Stakes runner-up Sonning Rose (Hawk Wing). He should stay at least 6f and looks a fun type for Valmont and Michael Blencowe to go to war with in the coming weeks and months. 4. MAGIC EFFORT (GB)Good Effort (Ire) – Muhadathat (GB), by Showcasing (GB)Timeform performance rating: 83The 5f fillies' maiden run at Newmarket on April 15 also produced a tight finish, with Magic Effort proving the most clued up of the eight newcomers who went to post in getting the verdict by a head. Relatively unconsidered in the betting at 20/1, she was always right on the sharp end in the hands of Benoit de la Sayette, bef1ore finding plenty when tackled by Call Me Tomorrow (Minzaal) to keep that one at bay on the uphill climb to the line.Described by Timeform as “the clear pick of the field on looks”, with “plenty of strength for an early two-year-old”, Magic Effort seemingly has the attitude to match her impressive physique. This was certainly a promising start to her career – and, incidentally, that of Call Me Tomorrow, who also ran to a rating of 83 – with a tilt at something like the Listed Marygate Fillies' Stakes at York appealing as the obvious next step.Magic Effort is out of the dual winner Muhadathat, but perhaps more interesting is the backstory of her sire, which Emma Berry detailed in her Breeders' Notebook from Newmarket. In a nutshell, Magic Effort was the breakthrough winner from the small first crop of Abdulla Al Mansoori's stallion Good Effort, who reportedly has only four other juveniles to run for him in 2026. All five of them are owned by Al Mansoori and in training with Ismail Mohammed, who saddled Good Effort to win nine races in a career spanning 37 starts. 3. STAR PROSPECT (IRE)Starman (GB) – Swiss Kiss (GB), by Dansili (GB)Timeform performance rating: 90Joseph O'Brien's first two-year-old runner of the season, Star Prospect laid down a serious marker for those to come when easily winning the 5f contest which kicked off the Curragh's card on April 19, looking potentially smart in the way that he dispatched what was a strong field on paper.Held up in the early stages, the son of Starman appeared full of running when having to wait for a gap entering the final furlong. When he eventually did see some daylight, the response was immediate as he picked up in really taking fashion to seize control, ultimately winning by over a length from the Ballydoyle newcomer Carry The Flag (No Nay Never). Even in defeat, the runner-up ran to a rating of 85, showing form that would have been good enough to win most other maiden/novice events staged so far this year in Britain and Ireland.O'Brien described the winner as “all speed” in the aftermath, with all roads now leading to the G2 Norfolk Stakes at Royal Ascot if he can build on the immense promise of this debut. Bought for €135,000 at the Tattersalls Ireland September Yearling Sale, he is certainly bred to be fast as his dam – who has already produced four other winners – is a half-sister to the Group 3-winning sprinters Swiss Diva (Pivotal) and Swiss Spirit (Invincible Spirit). 2. ADAAY OF SCARLETT (IRE)Mehmas (Ire) – Adaay To Remember (GB), by Adaay (Ire)Timeform performance rating: 94The 5f novice run at Newmarket on April 14 probably wasn't the deepest renewal of that race ever staged, but it still produced an impressive debut winner in Adaay Of Scarlett, who proved himself in a different league to his four rivals. Positively ridden by Oisin Murphy, he travelled fluently from the outset and it was soon over as a contest once he moved to the front over a furlong out, drawing right away from there to win by over four lengths in emphatic fashion.Trainer Hugo Palmer confirmed afterwards that Royal Ascot is already uppermost in his thoughts, with an appearance on the Lockinge undercard at Newbury next month potentially being used as a stepping stone. Wherever he goes next, it will take a good performance to lower the colours of a colt who, with a Timeform master rating of 94p, finds himself behind only Adonius (Soldier's Call) (97) among the best juveniles we've seen so far in Britain.The second two-year-old winner for Mehmas in 2026 after Wait Geordie, also trained by Palmer, Adaay Of Scarlett is the first foal out of the G3 Summer Stakes runner-up Adaay To Remember who, in turn, is out of a half-sister to the G2 Sapphire Stakes winner and multiple Group 1-placed Stepper Point (Kyllachy). It's a pedigree which is all about speed and which persuaded his connections to part with €110,000 to secure him at last year's September Yearling Sale. 1. GREAT BARRIER REEF (IRE)No Nay Never – Gems (GB), by Haafhd (GB)Timeform performance rating: 97Having been backed as if defeat was out of the question, No Nay Never's Great Barrier Reef duly delivered a blockbuster debut effort when winning the 6f maiden run at the Curragh on April 19. At the line he was fully seven lengths clear of the chasing pack, with the testing conditions doing little to halt his momentum as he forged ahead late on, running out a resounding winner of the same maiden in which Ballydoyle introduced Little Big Bear in 2022 and then Whistlejacket in 2024.Whereas Little Big Bear and Whistlejacket were both turned over on their respective debuts, Great Barrier Reef immediately looks ready for a step up in grade, with his unbeaten record intact and the distinction of being the first two-year-old to earn 'TDN Rising Star' status in Europe in 2026. For good measure, he's also leapt to the top of Timeform's juvenile rankings with a master rating of 97p, with the 'p' attached to his figure – denoting that he is open to more improvement – setting him apart from Adonius.A full-brother to the G2 Superlative Stakes hero Mystery Power, Great Barrier Reef must be considered an obvious candidate for the G2 Coventry Stakes at Royal Ascot at this stage, albeit it's still very early days for those juveniles waiting for the 6f races. In Britain, they get underway during the week beginning April 20, three weeks earlier than in 2025, in response to feedback from trainers seeking earlier opportunities for juveniles over more than the minimum trip.
