The series was the conclusion of the 2018 Overwatch League playoffs and was played between the London Spitfire and the Philadelphia Fusion at the Barclays Center in Brooklyn, New York.

London Spitfire defeated Philadelphia Fusion in the first and second matches by scores of 3–1 and 3–0, respectively, to claim the title of Overwatch League Grand Finals Champions before a two-day attendance of 22,434 spectators.

The team then became the first-ever stage playoffs champions, after achieving victories over the Houston Outlaws (3–1) and the New York Excelsior (3–2) in a reverse sweep.

[9] On March 7, midway through Stage 2, the Spitfire parted ways with head coach Lee "Bishop" Beom-joon for undisclosed reasons.

[21] Using the stage-break to catch up on lost practice time and welcoming the arrival of Israeli DPS player Josue "Eqo" Corana, Stage 2 would prove to be a turning point for the team.

[24] After Dallas Fuel's upset 3–1 win over the Los Angeles Valiant on June 15, Philadelphia needed a 4–0 sweep over the London Spitfire in order to make the Stage 4 Playoffs.

[25] Philadelphia Fusion claimed the 6th seed in the Season Playoffs on June 15, after Seoul Dynasty lost to the Los Angeles Gladiators.

[29] Overwatch League commissioner Nate Nanzer emphasized that two factors influenced the decision to select the Barclays Center as the grand finals host: the venue's location in a prominent global city and its world-class status.

[41] The Nielsen ratings for the Grand Finals broadcasts on ESPN and ABC were relatively low compared to other programs that aired in similar time slots.

However, Nielsen estimates are based on television-owning households in the United States and don not provide a comprehensive view of viewership patterns.

Blizzard reported that the United States accounted for 289,175 of the average minute viewers, encompassing both the Twitch stream and the ESPN broadcast.

A notable point of contention surrounding DJ Khaled's performance stemmed from his past remarks, which were deemed sexist in nature.

Overwatch League host Malik Forté also expressed his thoughts on the artist choice on Twitter, emphasizing the importance of mutual respect and equal treatment within relationships.

While DJ Khaled demonstrated professionalism by completing the entire 15-minute performance, the overall reception was mixed, with some viewers questioning whether he was the most suitable choice for the Overwatch League event.

As the payload reached its final destination inside the building at the end of Dorado, the Philadelphia Fusion seemed to awaken to the urgency of the situation.

With just meters remaining for the payload to reach its final destination and nearly three minutes on the clock, the Spitfire encountered a formidable obstacle against the Fusion's defense, led by Eqo on Hanzo and Carpe on Widowmaker.

In combination with the effective coordination of Hotba on D.Va and Sado on Winston, who provided crucial cleanup support, the Fusion managed to hold their ground and turn the tables on the Spitfire.

The Spitfire swiftly secured control of the capture area, establishing a dominant offensive presence, led by Fury's Roadhog and Birdring's Hanzo.

Led by Gesture and Bdosin, who played Zenyatta, the Spitfire took charge and successfully cleared out most of the Philadelphia damage heroes, seizing control of the point for themselves.

However, after the initial capture and a brief push of the payload, the London Spitfire regrouped and took advantage of Philadelphia's challenging choke point position on the map.

Nonetheless, the Spitfire's tank line, particularly Gesture's Winston, dominated the remainder of the match and halted Philadelphia's progress along the way.

However, with about 50 seconds remaining, the Spitfire executed a decisive push and successfully captured the point, thanks in part to Gesture's performance on Winston, which proved instrumental once again.

Needing a win to save the series, the Philadelphia Fusion encountered initial challenges, struggling to make significant progress on the opening point against the defense of the Spitfire.

Despite the tough start, the Fusion found a glimmer of hope when a few careless mistakes by the Spitfire players allowed Poko on D.Va and Eqo on Zarya to execute a near team kill.

Unconventional in their approach, the Fusion adopted a more aggressive defensive style, led by Hotba on Roadhog, which proved highly successful in nearly fully holding London off the point.

Despite facing a tight situation and limited time on the clock, the Spitfire secured a crucial elimination on Mercy, shifting the momentum in their favor and capturing Point A.

[51] However, in the closing moments, Profit swapped to Tracer and picked up five critical final blows in a span of 93 seconds, and the Spitfire captured Point B, securing the victory in the series.

[54] On London's attack, Gesture on Orisa and Bdosin on Roadhog consistently combined their abilities to create a force that proved challenging for the Philadelphia Fusion to defend against.

On the first sub-map, Night Market, the Spitfire completely dismantled the Fusion, strategically forcing them into vulnerable positions and capitalizing on those opportunities to pick off their opponents.

[53] London executed their game plan flawlessly, preventing the Fusion from gaining a single percentage on Night Market, resulting in a decisive victory for the Spitfire.
