The fastest three year old in the Southern Hemisphere

The fastest three year old in the Southern Hemisphere

Muscle Factory became the fastest three year old ever in the Southern Hemisphere with a stunning 1:49.6 win in the Group Two Simpson Memorial at Menangle on Saturday night. (Watch Replay)

The Group One winning son of Roll With Joe was first up as a three year old but that didn't stop him from making all the running and sprinting away for a historic win.

Bred by Jared Kahlefeldt, Muscle Factory is out of the Jeremes Jet mare Malena, she a grand daughter of the outstanding broodmare Mistron.

Given this was his first run for the season, Muscle Factory looks set for a big year!

Remarkably Roll With Joe can now lay claim to siring the fastest ever 2yo in the Southern Hemisphere (Ignatius) and the fastest ever 3yo in the Southern Hemisphere (Muscle Factory).
