"This whole event is for sure in memory of him. We wouldn't have this event if he did not pour his heart and soul into this track."
Semenuk said ever since he first roomed with McGarry they became good mates.
"I hung out with him a lot. I can't remember the first time I met him, but I remember the first time I roomed with him at an event.
"He came in and his arm was all bandaged up from the event before, and he was just the nicest guy ever, we got along instantly.
"Then he had a crash the next day on the course and his arm was even more battered, and he had a cast on it.
"But just being Kelly he took the cast off and still rode the event and killed it. And that goes to show how awesome he was ... and he just wanted to be apart of what we have."
Semenuk was rapt to win today after crashing out of contention last year at the same event.
"It feels good always to lay down a good run and walk away with a win, I'm so stoked. And I love this course so to get the run I wanted feels good."
Nicholi Rogatkin (US) finished second with last year's champion Brett Rheeder (Canada) finishing third. Semenuk won $20,000 for winning the event.
