SHE Will Reign, the fastest juvenile in training, raced into Golden Slipper favouritism with another stunning win at Royal Randwick on Saturday.

The unbeaten filly began slowly but accelerated through to lead within 200m and was never challenged as she romped away with the $500,000 Inglis Nursery (1000m).

The Gary Portelli-trained She Will Reign handled the heavy track expertly as she sprinted clear to win by four lengths easing down, running 58.57sec and breaking 35sec for the last 600m despite the heavy 8 track rating.

“She is fast, strong, a natural,’’ Portelli said.

“At the start, she half went backwards and it took a little while to get to the lead but when she quickens she puts it beyond doubt very quickly.

“Up to 1100m, there is not too many around that can beat her. The jury is out on how far she will get, but our next job to teach her to run the trip.’’

She Will Reign was so impressive, TAB Fixed Odds price assessors elevated her to $8 outright favouritism for the $3.5 million Golden Slipper (1200m) at Rosehill Gardens on March 18.

The Inglis Nursery is a restricted sales race and the $270,000 prizemoney She Will Reign earned on Saturday does not count towards Slipper qualification.

But Mossfun won the Inglis Nursery in 2013 before winning the Golden Slipper in 2014 and this is the path Portelli will take.

She Will Reign ($2.10 to $1.90 favourite) was simply too fast and too good for first starter Diamond Tathagata ($41) with a short-head to African Rainbow ($81).

Serena Bay also missed the start but, unlike She Will Reign, did not have the speed to get up on the pace before working home to run fourth.
