Sent out the $3 favourite, the son of Magnus made it two wins from three starts when he beat a crack field to win the rich juvenile event by a length.

Stored Energy made ground late, but The River’s win was never in doubt and the margin at the post was a length. The Celt was third home a further three and three quarter lengths back.

The win was the second in the race for jockey Shaun McGruddy, who rounded out the day with four winners, while it was a record fourth win for trainer Trevor Andrews.

The River was purchased by Andrews for $115,000 at last year’s Magic Millions Perth Yearling Sale from the draft of Western Breeders Alliance – bred by the Atwell family’s Darling View Thoroughbreds.

He debuted with a strong win on January 9 after a couple of trial wins and then was narrowly beaten at his most recent run, gunned down by stablemate Trademark by a half length at Ascot on January 23.

In form jockey Shaun McGruddy got the youngster into a lovely spot early and soon after straightening for home he was presented and the exciting juvenile showed a great turn of foot to race to the lead and win emphatically.

A son of Flying Spur’s Galaxy winner Magnus, The River is one of four winners, from four to race, for the Perth two-year-old winning Real Jester mare Jestceny.

Jestceny is doing a great job at stud having already produced three city performers from as many runners including the stakes perfomer Jestpatim.

The latest yearling from Jestceny, a colt by first season sire Your Song, will be offered early in this year’s Perth Yearling Sale – as Lot 3.

Meanwhile, stakes winning filly Let it Slip added another black type victory to her record when she scored a stunning win in the $150,000 Magic Millions WA 3YO Trophy (1200m) later in the afternoon.

Allowed to settle back in the third pair of runners, the Not a Single Doubt filly was able to burst through the field after a copybook ride from Jarrad Noske to win by almost half a length from The Cobbla, while Rhi’s Rocket was a breath back in third place in a busy finish.

Let it Slip provided trainer Daniel Pearce and jockey Jarrad Noske with their second wins in the Magic Millions 3YO feature. Pearce won with Testamezzo in 2014, while Noske won it a year earlier aboard Express Service.

From just eight starts to date Let it Slip boasts three wins and three minor placings from just eight starts – her two black type victories have helped her earnings soaring past $230,000 already.

Let it Slip is the first winner to date for the Sydney winning and well related General Nediym mare Oopsy Doopsy. She was bred by Dr Chris Gales and sold through the draft of Gervase Park Stud for $130,000 at the 2014 Magic Millions Perth Yearling Sale.

A winner of four races to 1350 metres, Oopsy Doopsy is a blood sister to Red Hot Mama (the stakes winning dam of Mama’s Choice) and half sister to the stakes performed Little Bit Ditsy.
