"We were down 23-15 with five minutes to go. Alex Hartford kicked a penalty to make it 23-18. In the last minute, we had the ball on our ten-meter line," Syme told College Sport Media.
"I took an offload from Campbell Reid which put me in a gap. I managed to beat the fullback and score under the posts. Alex kicked the conversion and we won the game."
"When I got onto the field, I thought I was just going to make a few tackles and pass the ball around, I never thought I'd actually get the try," he said to The Christchurch Star.
That exhilarating two-minute cameo catapulted Syme into the 1st XV's starting side on a permenant basis, allowing him to showcase his spectacular array of skills, highlighting his outrageous flick passes and electric pace.
As a result, he was called into the Crusaders under-18 side as an injury replacement to play the Hurricanes under-18 team at Westpac Stadium, a match the Crusaders side went on to lose 25-10.
Back at Christchurch Boys', Syme helped his side to the UC Championship title, defeating Timaru Boys' High School 28-10 in the final. However, their National Top Four aspirations were snatched away from them in the final minute of the South Island qualifying final against Southland Boys', going down 36-31 to the Highlanders champions in Invercargill earlier this month.
While that marked the end of the season for CBHS, Syme's outstanding campaign was rewarded by being named as one of two Chirstchurch Boys' players in the 49-man New Zealand Schools rugby development camp last week.
Following a three day camp starting on Friday, the enlarged squad will be split into the New Zealand Schools squad, which will play three matches in Sydney, and the New Zealand Barbarians Schools side, which will play two games in Palmerston North.
No matter which squad Syme ends up being apart of, his selection for national honours caps off a whirlwind three months after making his 1st XV debut just 13 weeks ago.
Syme will join the Crusaders academy next year to begin his journey into professional rugby, an astonishing feat for a player who, prior to this year, last played rugby in year 10.
