2/24 (GP): Fountain of Youth (Gr. II)

Coa has ridden Anak and Court Vision and now on E. Fields.
I find this interesting. I have no idea about arrangements
and trainers likes and dislikes with Jockey's "fitting" certain
horses. Is it that Coa made this choice and will it be as
bad as Calvin's decision to take Turf war getting off the
winner...?
I dont often trust the Jockey's decisions if they are given
that privilege.
