Hot prospect Blue Shadow closed out her three-year-old campaign in style with a runaway success at Te Rapa.

The daughter of Dalghar was untroubled by the outside gate in Saturday's McMillan Equine Feeds 1200 and she didn't need to find top gear to win in a canter.

"She's very good, she's special," Cambridge trainer Graeme Hughes said. "It's a bit frightening really. She's an exciting sprinter and we're looking forward to the future."

Blue Shadow finished fifth in her April debut and she then broke her maiden at Matamata before beating a tidy line-up of three-year-olds at Te Rapa last month.

Her return to the Hamilton track on Saturday produced the best performance of her fledgling career. She showed good gate speed to cross the field to lead and travelled comfortably to the turn.

When rider Sam Spratt asked Blue Shadow to lengthen stride on straightening they coasted clear to score by nearly five lengths.

"I'm very happy with her, she's done everything right and this is her last start," Hughes said. "She can have a break now until the spring."

Blue Shadow is raced by Colin Bishop, his brother Des and their sister Astrid Morgan, the siblings having purchased the filly at Karaka from Seaton Park's 2015 Festival Sale draft for what now seems a bargain $18,000.

Mystery Show, who earlier this season placed in the Gr.3 Gold Trail Stakes and the Listed Soliloquy Stakes, was a distant second ahead of last season's Listed Trevor Eagle Memorial winner Alamer.
