 Chelsea Rose missed the first part of the 2005 season, and returned to the track in the Silver Stakes over ten furlongs at Lepardstown on 8 June in which she was matched against male opposition and older horses including Sublimity, Solskjaer (Royal Whip Stakes) and Napper Tandy (Diamond Stakes).Carrying a seven-pound weight penalty for her Group 1 win she took the lead in the straight and rallied after being headed by the favourite Merger to regain the advantage and win by a head.In the Pretty Polly Stakes two weeks later she started second favourite but ran poorly and came home ninth of ten runners behind Alexander Goldrun.
