The Olympic Winter Institute athlete successfully moved through the early qualifying rounds last Friday, and in the quarter finals today finished second to progress to the semi-finals, from where the top two from each would make it to the A Final.
Locket, 19, came up against two dominant Korean skaters in her semi and narrowly missed making to the final having finished a close third.
The B Final was cancelled, leaving Lockett officially in 6th place, adding to her 8th in the 1500 metres yesterday.
"The semi- final was difficult with the two Koreans, as they were looking to block me, but even though it's difficult I have to learn to deal with that,” Lockett said. “I suppose the positive about their tactics is that it shows they are thinking about me now.
"I used too much energy in my quarter finals, which is another thing I have to keep improving – knowing that I can save energy for the semi-final and hopefully final going forward."
"I am really happy with how my first World Cup of the season went, I have definitely improved but I still have a lot of things I know I need to work on and hopefully I can make further improvements during the season."
In the men’s competition both Nathaniel Henry and Lazenby Armstrong were in action in the 1000 metres, taking part in the repechage heats. Armstrong was knocked-out, finishing third for an official 32nd place overall. In a promising performance, Henry made it through both the repechage heats and the repechage quarterfinals to finish in 24th place.
The next round of the ISU Short Track World Cup will be held in Montreal Canada from November 14-16.
