King Pulse - welcome back!

Untapped four-year-old King Pulse will be among contenders trying to topple Black Caviar for the first time in the Lightning Stakes at Flemington.

The gelding was among 13 nominations for Saturday's 1000-metre weight-for-age sprint but was also entered for The Big 6 Hcp (1200m).

"We were planning to run in the 1200 metre race but it worried us that it would be pretty tough on him because he hasn't had a run for such a long time," trainer Mike Moroney said.

"He is not well placed at weight-for-age by any means but 1000 metres seems better for him than 1200 even though it will be a stronger field."

King Pulse has been off the scene for 11 months after being badly injured in the devastating hailstorm that hit Flemington minutes after he finished fourth to Black Caviar's stablemate Wanted in the Newmarket Handicap (1200m).

The chestnut suffered a hairline shoulder blade fracture and a dropped hip when he took fright in the storm but Moroney said he was encouraged by his recovery and keen on his chances of regaining his best form.

"He seems to be back where he was," Moroney said.

"He has trialled up very well and won a jump out quite impressively last week."

King Pulse has only raced four times, featuring two impressive wins at Geelong and Caulfield and a Group One second to Headway when beaten in a photo finish in the 2009 Group One Coolmore Stud Stakes (1200m) at Flemington.

"He is untapped and we will be happy if he is competitive on Saturday," Moroney said.
