[2] Chriselliam's dam Danielli failed to win a race but was a half-sister of the Moyglare Stud Stakes winner Priory Belle.
[3] The filly became the property of a partnership of Willie Carson, Emily Asprey and Christopher Wright and was sent into training with Charles Hills at Lambourn.
Chriselliam made no impact on her racecourse debut, finishing ninth of fourteen runners in a six furlong maiden race at Haydock Park in May.
She reappeared in July for a seven furlong maiden race at Warwick Racecourse, and recorded her first success, winning by two and a half lengths at odds of 5/1.
Ridden by Gerald Mosse, she took the lead in the straight but was overtaken in the final strides and beaten a neck by the Richard Hannon Sr.-trained colt Chief Barker.
The Moyglare Stud Stakes winner Rizeena was made the 7/4 favourite, while Chriselliam, ridden for the first time by Richard Hughes started a 28/1 outsider.
[7] On her final appearance of the season, Chriselliam was sent to California to contest the Grade I Breeders' Cup Juvenile Fillies Turf over one mile at Santa Anita Park.
