Jockey Dean Holland has been suspended and fined for breaching the whip rules on Zacada, who was beaten a nose in the A$2 million Sydney Cup.
Holland was put out for one week and hit with a A$3000 fine for using the whip 12 times before the 100-metre mark in yesterday's 3200-metre race, seven more strikes than allowed under the rules.
Zacada darted through along the inside in the straight to hit the front before going down in a photo finish to veteran stayer Who Shot Thebarman.
Holland was one of three jockeys suspended on the second day of The Championships. Andrew Adkins was banned for seven meetings after pleading guilty to careless riding aboard Daysee Doom in the Coolmore Legacy Stakes.
His suspension is due to start after next Saturday's Randwick meeting and he can resume riding on May 9.
Melbourne jockey Luke Currie will begin a seven-meeting suspension immediately after pleading guilty to careless riding in the Australian Oaks on eventual fourth placegetter Bring Me Roses.
