          Kiwoom	45	95	4	0.3214	37.5

To construct the scenario, we start with the current standings:
            Team	W	L	D	GL	PCT	GB
              LG	79	48	3	14	0.622	0.0
          Hanwha	75	52	3	14	0.591	4.0
             SSG	65	59	4	16	0.524	12.5
              KT	64	62	4	14	0.508	14.5
         Samsung	65	63	2	14	0.508	14.5
           Lotte	62	64	6	12	0.492	16.5
              NC	59	62	6	17	0.488	17.0
             KIA	60	64	4	16	0.484	17.5
          Doosan	56	68	6	14	0.452	21.5
          Kiwoom	42	85	4	13	0.331	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:
