Vinci may be no artist, but she's a tough competitor and a proven winner, who helped Italy win the Fed Cup this month and who will certainly enhance the doubles event, as well as set the standard in the singles.
On her one previous visit, in 2012, 30-year-old Vinci lost in the second round to Russian Elena Vesnina, who is back and fifth seed, and hoping to go one better than being beaten finalist four years ago.
There are four Americans in the field, headed by fast-rising Jamie Hampton, and one former champion in Belgian Yanina Wickmayer, while New Zealand's best player, Marina Erakovic, sits 11th on rankings.
Williams was due to appear in 2011 but was a late withdrawal due to illness. Budge is confident there won't be a repeat. "Based on what we're paying her you can see very clearly Venus wants to be here and playing."
The entry cutoff is 71, seven spots better than a year ago. The tournament starts on December 30.
