"We have given her the work, but those scales have continued to go up.
"She was 512kg on Boxing Day (when runner-up in the Listed Hallmark Stud Handicap (1200m)), then 516kg on New Year's Day, she had a gallop in-between because she was doing so well and still put on four kilos in those six days. Now she has jumped to 522kg.
"We always take it as a positive when horses are putting on weight and racing really well, so we are expecting much of the same."
Ralph is hoping she can continue her winning ways on Saturday despite being hampered with more weight. "She is absolutely jumping out of her skin and we expect another good showing from her.
"I can't see why she won't perform well again on Saturday. I know the weights are going to be against her after she jumped 19 rating points (after her Railway victory). That's going to really level the playing field."
If all goes to plan on Saturday, Santa Monica will be aimed at the Gr.1 Newmarket Handicap (1200m) at Flemington on March 9.
"We would love to get her there, the Aussies think they're pretty good, but we've got a good horse too, so we would love to go over there and have a tango with them."
