The Korean midfielder missed a penalty but converted the rebound to help his team claim bragging rights in the traditional clash
Alex Weaver’s side went a goal down in the 15th minute when referee Abdul Malik awarded a penalty to the Protectors after Jeremy Chiang was adjudged to have brought down Lee in the box.
Goalkeeper Hassan Sunny denied the Korean from the spot but the midfielder followed up on the loose ball and lashed it in to give his side the lead.
There was no dominant side in the match as both teams had their fair share of possession, making use of the flanks for most of their attacks.
The Warriors defense was looking more organised and disciplined compared to their time under previous coach V. Selvaraj earlier in the season.
Weaver had experimented with his starting line-up by slotting captain Daniel Bennett into defensive midfield alongside ex-Japanese international Kazuyuki Toda, while deploying Sufian Anuar as a lone striker with star forward Mislav Karoglan suspended.
But Bennett lasted only 45 minutes as the Englishman brought on Erwan Gunawan in place of the former Singapore international at the start of the second half as they sought the equaliser.
Home could have doubled their lead on numerous occasions after the break but they were denied by the heroics of Hassan, who was having one of his best games of the season.
A minute after the hour mark, Indra Sahdan sent a delicate cross from the left to the far post but Ismail Yunos’s header was punched away for a corner by Hassan.
Although Warriors penetrated their opponent’s defense a few times in the final quarter of the match, they posed little threat to Home custodian Shahril Jantan with several off-target attempts.
Sufian cleverly shook off his marker and connected with his head to Tatsuro Inui’s corner, but the diminutive striker could only see his effort shave off the bar in the 76th minute in his team's best chance to level the game.
With the result, the Warriors are now a loss away from cementing their spot in the bottom six, with the S.League table set to split into two for the newly introduced half round after the first two rounds of games.
