Zenyatta has drawn post 5 in a field of six for Sunday's $250,000 Vanity Handicap, where the 6-year-old mare will be attempting to stretch her unbeaten streak to 17 races. The rest of the field, in post position order, is Miss Silver Brook, St Trinians, Zardana, Will O Way, and Cherryblossommiss. Zenyatta will be ridden by Mike Smith, who will make a public appearance to discuss the mare's career in the Hollywood Park paddock at noon Saturday.
