It was the All-Scars' first appearance at Big O, one of the biggest tournaments held annually in America.
There was no final/semi-final - teams were matched up before the events for these mostly sanctioned WFTDA (world ranking points) games.
The All-Scars world ranking has improved accordingly, bumping up to a New Zealand high of 52 after languishing at 87.
Conn commutes to training at the Trust Arena in Henderson multiple times weekly, car pooling with two other team mates from Hamilton.
"With playoffs only three weeks away, we are focusing on what we want to achieve in Pittsburgh," Conn told the Courier.
"We are implementing different strategies and adapting ourselves to the high level of play we'll be facing, which makes for exciting times within our league and also throughout New Zealand roller derby."
The Rachael Riley coached All-Scars have worked tirelessly to move up the international rankings over the last three years, none more so than Conn.
"During her time on the squad, Kareena has shown incredible tenacity and focus which has helped her to evolve into one of the regular rotation jammers (point scorers) who will be representing the team at the WFTDA division two playoffs in Pittsburgh," says Riley.
"Her strong hits and positive attitude on and off the track make her an asset and a pleasure to have on the team."
Conn got to play in the Tri-City, Chicago, Sydney and Windy City games.
"Windy City - the highest ranked team we played at #38 at the time and the only one we lost to - was incredibly challenging.
Although we lost, we were so grateful to be able to play such an amazing team. We definitely came away with a lot of ideas on how to improve.
"We owe a massive thanks to Sarah Hipel, Frightmare and Dual Hitizen, top US roller derby athletes, for bench managing us while we were over there.
Their wealth of knowledge - and maths - was incredibly helpful."
The All-Scars are peaking nicely for playoffs, having recently beaten Dunedin 332-61 and Whakatane 235-7.
Her team gets no funding, so fundraising is a massive part of their quest to compete in back-to-back tournaments in the USA.

FOOTNOTE: Roller derby is a contact sport played by two teams of five members roller skating in the same direction (counter-clockwise) around a track.
Game play consists of a series of short match ups (jams) in which both teams designate a jammer who scores points by lapping members of the opposing team.
The teams attempt to hinder the opposing jammer while assisting their own jammer - in effect, playing both offence and defence simultaneously.
The sport is played by approximately 1250 amateur leagues worldwide, nearly half of them outside the United States.
Modern roller derby is an international sport dominated by all-female amateur teams, in addition to a growing number of male, unisex and junior roller derby teams, and was under consideration for the 2020 Summer Olympics.
