She ran sixth in her only run as a two-year-old in 2018 and showed promise in the following spring when she won on her seasonal debut and then finished third in the Fillies' Trial Stakes.
Star Catcher is a bay filly with no white markings bred in England by her owner Anthony Oppenheimer's Hascombe and Valiant Stud.
[7] Star Catcher made her first and only appearance as a juvenile in a maiden race over one mile on the synthetic Polytrack surface at Chelmsford City Racecourse on 20 December.
Ridden by Robert Havlin she was made the 4/5 favourite but never recovered from a slow start and came home sixth of the twelve runners, six and a quarter lengths behind the winner Mister Chiang.
The other nine runners included Queen Power and Frankellina (second in the Musidora Stakes) as well as Star Catcher's well-fancied stablemates Fanny Logan and Sparkle Roll.
Star Catcher raced in mid-division before taking the lead early in the straight and pulled away in the final strides to win by one and a half lengths from Fleeting.
Star Catcher led from the start, accelerated clear of her opponents in the straight, and held off a late challenge from Fleeting to win by half a length.
[13] After a late summer break, Star Catcher returned on 15 September at Longchamp Racecourse when she was matched against older fillies and mares in the Group 1 Prix Vermeille over 2400 metres.
Star Catcher took the lead at the start and made all the running, staying on well in the straight to win by three quarters of a length from Musis Amica.
