Formerly trained by Tony McEvoy, Miss Siska joined Begg for her current campaign and first-up on Saturday in Bendigo Gold Bracelet raced to an impressive win.
Begg said Miss Siska arrived at his Pinecliff stable in great order only a “few weeks” before lining up on Saturday.
“It's great for her to come here today because it looked a light race with the set-weights and penalties,” Begg said.
“She came to us and was ready to go but had missed a lot of the autumn which might be a bit of a blessing in disguise.
“We want to get her going for the spring so I said to the connections we need to get her rating up a bit more if we want to get a run in those better races.”
