Okay upper semi, how throwable is this match? Because there is a chance that they won't want to so much of their hands. If they wanna win, they'll probably skip a match but as shahzam and dapr said, having played an extra game on LAN isn't at all a disadvantage as u don't have to adjust in the more competitive matches.
On the other hand, 100Thieves looks like they want to finally win something in a long time and Sentinels has a winning mentality to cement themselves as NA best.
