Solar Charged showed why trainer John O'Shea had been so keenly anticipating her debut when she scored a commanding five-length win at Randwick.

The Randwick horseman is sending the filly to the paddock and will bring her back for the autumn two-year-old features after she set a course record of 57.97 seconds for the Kensington track, eclipsing the previous record held by Savabeel (58.68s) who went on to win the 2004 Cox Plate.

Solar Charged is by the former O'Shea-trained Group One winner Charge Forward and punters expected something above average too, sending her out the $2.40 favourite in the Jim Beam Handicap (1000m).

Out of the Danehill mare Soul Singer, Solar Charged was coming off a 4-3/4 length barrier trial win at Randwick on November 13.

Solar Charged is bred and owned by Peter Horwitz who also raced Charge Forward, the winner of the 2005 Group One The Galaxy (1100m).

Connections originally thought the filly would be given 53.5kg and not the 54.5kg she had at Randwick and so Corey Brown claimed the ride from regular stable rider Hugh Bowman, who rode the unplaced Platinum Choice.

Solar Charged jumped well from her wide alley and led on settling before Platinum Choice took over near the halfway point.

Platinum Choice led at the 400 metres but was under pressure while Brown cruised up to join him on Solar Charged shortly after and she exploded away in the closing stages to defeat Extreme Mover ($4) easily with Miss Opulence ($31) 1-1/2 lengths third.

"You hope for those sorts of things and you think those sorts of things but you don't want to say them out loud," O'Shea said.

"I said to Peter (Horwitz) yesterday that I didn't think there was much between her and her father at the same stage," O'Shea said.

Melbourne Cup-winning jockey Brown was glowing in his praise of the filly.

"I haven't ridden a Golden Slipper winner but she is one of the most impressive two-year-olds I've ever ridden," Brown said.

Charge Forward won the Group Two Todman Stakes as a juvenile before running a short neck second to Dance Hero in the 2004 Golden Slipper.
