She raced up on the pace and scored a three-quarter length win for Damien Oliver, her seventh win from 13 starts with prizemoney topping $330,000.
Jamaican Rain was bred and sold by Newhaven Park, fetching $90,000 at the Magic Millions Yearling Sale when bought by Homann Bloodstock with Newhaven Park retaining a share in her ownership.
She is the best of two winners from Heriz, an unraced Redoute's Choice mare from an international family that features Group I winners Asi Siempre and Outstrip.
Heriz has not had a foal in the past two years but was covered last spring by Pierro.

Line breeding to blue hen Shantha's Choice, the dam of Redoute's Choice and Manhattan Rain, has been done quite a bit.
So far the stats for line breeding to Shantha's Choice according to Arion show it has produced 98 named foals, with 30 winners from 56 runners or 53.6% winners to runners.
There are three stakes-winners bred this way in Group II winner Summer Sham ( 3 x 3), who is by Not a Single Doubt from a grand-daughter of Shantha's Choice and New Zealand stakes-winner Manhattan Street (2 x 3), who is bred the same way as Jamaican Rain.
Two further stakes horses include Group I placed Man of Choice, who is also by Manhattan Rain from a daughter of Redoute's Choice and if you were wondering about the stats on that specific cross it has produced 20 named foals, 19 have raced and 10 have won.
Manhattan Rain stands at Blue Gum Farm in Victoria and covered 80 mares at a fee of $19,250 last spring.
