With the first week of the Rocket League Championship Series wrapped up, it's time to go over the power rankings look back at the biggest matches from the start of the season.

Note: Power rankings are starting fresh in RLCS, and will only be based off results in official RLCS competition. Teams are ordered by standing, and their Power Rank (PR) is noted next to the record.

North America

1. Selfless Gaming

2-0 match record (6-2 game record) Power Rank: 3

Week 1 was a solid start for Selfless, beating Genesis and Set To DestroyX. The pace at which Selfless played was tough to deal with and is why the team deserves a spot in the top three.

2. NRG eSports

2-0 (6-2) PR: 2

NRG took down Atelier and Set To DestroyX but didn't look entirely convincing doing it. NRG has the skill to be a top team, but it seemed like there were few kinks to work out before they can achieve that potential

3. G2 Esports

2-0 (6-2) PR: 1

G2 had the match of the day versus Atelier before moving on to a very solid sweep over Denial. If the G2 that played Denial shows up consistently, it will earn the squad a spot at the top of the rankings.

4. Denial Esports

1-1 (3-3) PR: 4

Denial got swept, but also did some sweeping of its own. Getting swept by an in-form G2 isn't embarrassing for Denial and the sweep of Take 3 looks very good.

5. Genesis

0-1 (1-3) PR: 5

Trevor "Insolences" Carmody is possibly the most in-form player in North America, but unfortunately it wasn't enough for Genesis to overcome the offense of Selfless.

6. Take 3

0-1 (0-3) PR: 6

Take 3 got swept by Denial and never really looked to be in the series. Scoring only two goals in three games, Take 3 doesn't look great right now. The team will need to pick up some offensive firepower if it wants to move up the standings

7. Atelier

0-2 (3-6) PR: 7

Atelier looked better than its score would indicate, but it remains to be seen how the team will stack up against Take 3 and Genesis (the teams around them in the rankings). Those matches will be huge for Atelier as it looks to make a push into playoffs.

8. Set to DestroyX

0-2 (2-6) PR: 8

Set To DestroyX played the two top teams in North America, and taking two games out of those matches is a good performance from the team formerly known as Radiance.

Key Matches

Atelier versus G2: G2 battled back from two games down, and after being three goals down in Game 5, the team rallied to take down Atelier 3-2. Atelier went 0-2 in Week 1, but facing up against G2 and NRG is always going to be brutal and Atelier will take heart from how well they did overall. If you missed this series, it is mandatory viewing, truly a match of the year contender.

Selfless versus Genesis: Selfless started the day with an electric offensive performance, taking out Genesis to make a statement. Selfless' speed was second to none as it stamped its authority that it is ready to take the step up and compete with the top teams. It is worth noting that Selfless was in the first game of the day, so a lack of time spent "warming up" could have led to Selfless' pace advantage.

Europe

1. The Leftovers

2-0 (6-4) PR: 2

The Leftovers completed what could easily be one of the most incredible single day group of results in Rocket League. Taking down both Flipsid3 and Northern Gaming 3-2. It is not possible for The Leftovers to start stronger, and if the squad takes down Pocket Aces, it could become a consistent number one team.

2. Pocket Aces

1-0 (3-1) PR: 1

Pocket had one game in Week 1 and it was against Mock-it Esports, who were dispatched soundly 3-1. Pocket looked good, but we need to see games against the other elite teams in Europe.

3. Cow Nose

1-1 (5-4) PR: 6

Cow Nose had a great day taking down Secrecy before pushing PENTA to five games before being defeated. A solid start for the underdogs of the group, but if Cow Noses wants to hold onto a playoff spot, there is a hard grind ahead.

4. FlipSid3 Tactics

1-1 (5-5) PR: 3

What happened to FlipSid3 Tactics? Being reverse swept by The Leftovers before a small return to form beating Mock-it in five games is not the start anyone was expecting.

5. Northern Gaming

1-1 (5-5) PR: 4

Northern had a bad day at the office, squeaking past PENTA 3-2 before losing to Leftovers 3-2. Northern, who many had second in the world coming into RLCS, will need to improve.

6. Penta Sports

1-1 (5-5) PR: 5

Penta, who only made it with a last-chance qualifier due to the disqualification of ZentoX, had an up and down Week 1. Sneaking past a surging Cow Nose 3-2 isn't up to par, but taking Northern Gaming to five games will be a good base to build on for Penta in RLCS.

7. Team Secrecy

0-1 (1-3) PR: 8

Team Secrecy only played one match this week and after its dismal performance against Cow Nose, that will be a godsend. Secrecy have a lot to work to do if it wants to compete with the top squads in Europe.

8 Mock-it Esports

0-2 (3-5) PR: 7

Mock-it's struggles would have been the shock of the week if Leftovers hadn't made an incredible statement. Mock-it dropped to both Pocket Aces and FlipSid3, and when there are only seven matches to make playoffs starting off with two losses is brutal -- especially for a team with the lofty aspirations of Mock-it.

Key Matches

PENTA versus Northern: Northern took down a PENTA team which only qualified as the replacement for the disqualified ZentoX. The surprise came when PENTA took Northern to a fifth game where eventually the skill of Northern -- spearheaded by David "Deevo" Morrow -- came through. This set shows just how competitive Europe is shaping up to be in Season 3, and if this level of play continues, the expected European dominance in international play seems quite likely.

Leftovers versus Northern and FlipSid3: The Leftovers took down both Northern and Flipsid3 with a 3-2 scoreline and it was easily one of the most impressive performances by any team on a single day. Both matches went to five games with Leftovers continuing its incredible form from the qualifiers with solid defensive play in all 10 games Leftovers made a statement for both the playoffs and perhaps beyond. If there is a single team to keep an eye on after Week 1, it is Leftovers.
