St Kilda's newest G-Train, as she's known around the club, is Caitlin Greiser, a 21-year-old soccer convert who played for South Melbourne and turned down an American college offer to play AFLW.

Greiser kicked two goals in St Kilda's first AFLW win at Moorabbin on Friday night, including the winning goal from 50 metres out. She also kicked two goals in the loss to Adelaide the round before.

The former soccer striker - who once scored eight goals in a match - said after the game that she was honoured to take on the G-Train mantle from St Kilda legend Fraser Gehrig.

“It’s pretty special to be honest [the nickname], it’s really big at the club so I want to make sure I play my best," she said.
