          Kiwoom	44	95	5	0.3165	42.0

To construct the scenario, we start with the current standings:
            Team	W	L	D	GL	PCT	GB
              LG	79	49	3	13	0.617	0.0
          Hanwha	76	52	3	13	0.594	3.0
             SSG	65	60	4	15	0.520	12.5
              KT	65	62	4	13	0.512	13.5
         Samsung	65	64	2	13	0.504	14.5
           Lotte	63	64	6	11	0.496	15.5
              NC	60	62	6	16	0.492	16.0
             KIA	61	64	4	15	0.488	16.5

          Kiwoom	42	86	4	12	0.328	37.0

The next two tables show, respectively, how many of their remaining games each team wins and ties against each of the other teams in the scenario:
