Black Caviar will have just eight rivals in Saturday's group 1 Goodwood in Adelaide as the champion mare shoots for her 21st consecutive victory.

The Peter Moody-trained Black Caviar came up with barrier eight for the $500,000 feature at Morphettville.

Black Caviar, with Luke Nolen to ride, will carry top weight with 57kg, a half kilogram more than the Mark Kavanagh-trained Catapulted who came up with barrier two.

The Goodwood, a 1200metre sprint, will be Black Caviar's final appearance before she heads to England for the group 1 Diamond Jubilee at Royal Ascot.

The world's highest-rated sprinter, Black Caviar is at $1.04 with TAB Sportsbet to win Adelaide's premier sprint.

Go The Knuckle, who has barrier three, is next in the market at $21.

Black Caviar attracted a crowd of 30,000 when she won the Sportingbet Classic at Morphettville last month.

South Australian racing officials are expecting another sell-out crowd on Saturday.

■ MEANWHILE, Secret Indulgence, raced in the same ownership as Black Caviar, may have her first metropolitan start on her home track on Saturday after nominating for a $70,000 fillies and mares handicap over 2000m at Caulfield.

The three-year-old filly is nicely-bred, being by boom stallion Fastnet Rock and is a half-sister to Victoria Derby winner Amalfi.

She has had four starts at the provincials and broke through for her first win last start when trainer Peter Moody stepped her up in distance to 1900m in a three-year-old maiden race at Geelong on April 27.

Secret Indulgence romped in by 4¾ lengths from Vincente when second-up from a spell, indicating that there are better wins to come.

She races in similar colours of salmon and black but while Black Caviar sports black spots, Secret Indulgence carries black diamonds.

Honest mare Placement, from the Danny O'Brien stable, heads the weights with 60kg ahead of last Saturday's Flemington 1700m winner Gail (55kg) and Manila Jewel (54.5kg) with the rest of the 22 nominations on the minimum 54kg.

Also on the Caulfield program is the second heat of the All Victorian Sprint Series over 1100m in which the Mick Kent-trained Philda heads the weights with 60kg. AAP
