The race at the top is heating up in the Call of Duty World League, Presented by PlayStation 4. Week 6 brought change in both North America and Europe, as we saw two big names take hold of the top positions. Meanwhile Stage 2 is drawing to a close in Australia/New Zealand, and we have two teams battling to secure the final Playoff spot.

Check out the standings and stories from Week 6:

North America:

It always seemed a question of when OpTic Gaming would ascend into the top position in North America, and it finally happened after Week 6. After dispatching Dream Team 3-1, OpTic Gaming met FaZe Clan in the marquee Match of the Week. Despite FaZe going up 2-0 in the series, OpTic Gaming would storm all the way back in a reverse sweep to take the win and the 1st place position in the region.

Joining OpTic Gaming with a perfect 2-0 week was Luminosity Gaming. While the hype seemed to be around Parasite's reunion with compLexity Gaming, it was Nameless, the player he replaced, who had the bigger debut week with his new team. With a 4-6 record that puts them in a virtual tie for the 8th and final Playoff spot, Luminosity will definitely be a team to keep an eye on in these coming weeks.

Europe:

We officially have a two-team race at the top of the European region, as Splyce finally managed to grab the top spot away from HyperGames. After going five weeks without a loss, HyperGames finally fell in a 3-1 result to Exertus. That gave Splyce just the opening they needed, as their 2-0 week with just one map loss propelled them over HyperGames due to Map Win/Loss %. The timing couldn't be more perfect for these two teams to go back-and-forth: Splyce and HyperGames will face-off against each other next week.

Australia/New Zealand:

There's only one week left in Australia/New Zealand Stage 2 and one Playoff spot still up for grabs. Tainted Minds have pulled to within one game of Team Immunity, but they'll need some help if they're to overtake them for 4th place. Both teams will play against eXcellence and Mindfreak in their final week of Stage 2, making this as fair as it gets to decide the final Playoff contender.

North America: 2pm PDT/5pm EDT
