Giants Gaming defeated Reason Gaming 3-1 in the Summer Promotion Tournament to secure their return to the EU LCS on Saturday.

In the regular season, Giants Gaming just barely managed to avoid auto-relegation by defeating Meet Your Makers in a tie breaker game. They finished ninth overall in the standings just under ROCCAT.

Reason Gaming on the other hand, just barely made it into the EU CS playoffs as the lowest seed. They played well in the playoffs however, defeating a heavily favored Gamers2 squad in the third place match to advance to the Summer Promotion tournament.

Here's how the series played out:

Game 1

The early game advantage went to GIA as they secured a small gold lead through superior farming power. First Blood went to RG as Xayoo ganked PePiiNeRO around seven minutes into the game. GIA then, began securing global objectives to extend their lead. By 18 minutes, GIA went up 2-1 in turrets and 2-0 in dragons.

The first major team fight took place around the dragon pit as both teams were unwilling to give up the dragon for free. Fr3deric managed to steal the dragon with a well timed smite and GIA secured their third stack of the game. The only consolation for RG was a single kill on Werlyb.

Going into the late game, GIA continued to grow their lead by out-rotating their opponents. They secured their first Tier 2 turret before the 25 minute mark and held a massive advantage in all global objectives.

With the lead, GIA successfully baited RG into the top side jungle around 30 minutes in to the game. The ensuing team fight went to GIA as they secured three kills in the exchange. With three members down, RG had no choice but to allow GIA to take the Baron completely uncontested.

The Baron empowered GIA team was too much for RG as they moved into the mid lane and took the middle inhibitor with ease. They rotated down to the bottom lane and wiped out RG four-for-none before ending the game in 34 minutes.

Game 2

GIA once again, got out to the early game lead. They secured first blood in the top lane as Werlyb and Fr3deric dove Kubon in the top lane. The GIA team was superior in the laning phase, getting out to a massive creep score lead going into the mid game. By 16 minutes, GIA went up 2-0 in turrets and got out to a significant three thousand gold lead.

RG made an effort to try and come back in the mid game. They won a major fight inside their own jungle 21 minutes into the game as Celaver was left unchecked for too long. The fight lead to four kills for RG in exchange for just one death and RG closed in on the gold lead.

Even with RG closing in on the gold lead, the mid game combo of Corki and Lucian proved to be too much poke. GIA began to group up and took down all of the RG Tier 2 turrets by 27 minutes.

To counter the massive poke and lane pressure RG sent Celaver to split push the middle lane. This was massively successful as he alone secured the middle inhibitor. With the middle inhibitor down, GIA made a very smart decisive move to move into the Baron pit. RG attempted to contest but were caught out in several bad positions, leading to GIA securing Baron and three kills.

With the Baron buff in hand, GIA's poke and lane pressure allowed them to quickly finish the game. They took the middle inhibitor by 30 minutes and retreated for a short time to restock their inventories. With their fourth and fifth items, GIA moved to the top lane and secured yet another three kills before ending the game in 32 minutes.

Game 3

For the first time in the series, RG got out to the early game lead. They secured first blood in the top lane when an early gank by Fr3deric went horribly wrong. With the kill RG was allowed to dominate the top lane, securing two more kills in lane before the seven minute mark. By 16 minutes, RG got out to a one thousand gold lead, dominating the kill score 6-3.

The first major fight of the game took place in the bottom lane and it went to RG. They took down four GIA members in the extended exchange, leading to the bottom Tier 2 turret shortly after the fight.

Shortly after the turret fell, RG moved to the Baron pit, confident in their ability to take an early Baron. They secured Baron by 21 minutes completely uncontested, as GIA did not have vision around the pit. With the Baron buff, RG made their way down the middle lane and took the first inhibitor of the game.

The game slowed down soon after the turret fell, as RG did not take any risks, and elected to wait for a second Baron. Baron respawned around the 30 minute mark and a huge fight broke out. GIA had not choice but to contest RG around the Baron pit but RG absolutely demolished GIA in the fight and easily secured their second Baron buff of the game.

Empowered by Baron once again, RG moved down the bottom lane and wiped out their opponents one last time before ending the game in 31 minutes.

Game 4

First blood started an early game blood bath. The first kill went to RG just three minutes into the game as Werlyb fell to an early gank from Xayoo. GIA countered soon after, securing a revenge kill on Celaver in the top lane. Both teams continued to brawl, in the early game, trading kill for kill.

The mid game was even more chaotic as both teams just continuously battled each other. A long extended fight at the bottom lane around 17 minutes into the game ended in an eventual three-for-three as the kill score shot up to 19 kills by 18 minutes.

The dead lock was broken by GIA going into the late game. A key team fight took place around the middle lane around 25 minutes into the game. GIA took the fight convincingly as they secured three kills in the exchange.

Shortly after the fight, GIA pressured the top Tier 2 turret and found a pick off on Xayoo leading to a Baron attempt. They managed to secure Baron but were very low from the attempt and RG secured four kills as the GIA team made their way out of the pit.

GIA's team composition however, was better adept at catching the RG carries. They secured three quick kills in the middle lane securing the first inhibitor of the game by 31 minutes.

Just four minutes later, GIA confidently moved into the Baron pit having secured superior vision around the pit. RG were slow to react and GIA secured the Baron buff completely uncontested.

The ensuing team fight went horribly for RG as GIA were fully empowered by Baron. All five of the RG members fell in the extended exchange and GIA moved down the middle lane to take down the RG nexus in just over 36 minutes.
