TSM crushed XDG Gaming without any objection, and Cloud 9's superior teamfight coordination got them a win over Coast.  
OddOne explains the flaws of Zuna's Kha'Zix pick.     XDG started out with a smart plan to send Xmithie and Bloodwater top to get the first turret while TSM could not effectively damage the turret in the bottom lane with a melee support.  TheOddOne's Elise pick, however, allowed him to solo an early dragon, and Bjergsen dominated the mid lane, keeping TSM ahead in gold.   Zuna struggled to maintain the same map pressure as TheOddOne on a champion he seemed uncomfortable with, and Bjergsen used his lead to splitpush in other lanes.  XDG tried to combat the lead with a desperate baron attempt, but they lost two towers and a kill in response, and TSM continued to slowly strangle the game until a decisive teamfight top that won them the game.   Cloud 9 and Coast shake over a game that seemed close early.     Despite both solo lanes winning for Cloud 9, Coast managed to take a small lead with Shiphtur's roam bottom.  Cloud 9, however, managed to take uncontested dragons and play reactively until they could get the fights they wanted.     Balls used his lead from top lane to turn him into a massive, zone-controlling threat on Renekton that neither ZionSpartan nor NintendudeX and his ult could match.  NintendudeX couldn't get in position to get optimal ultimates to combo with Katarina, and Cloud 9 continued to win fights and take objectives until they won at forty minutes.
