Karachi Kings are likely to be dropped at the moment, as well as Quetta Gladiators that have won only 1 out of 6 matches. Karachi Kings threw a target of 201 runs in the 19th match of Islamabad United VS Karachi Kings. They needed to win 42 runs from 24 delivery. Since there are still enough wickets, Islamabad will win the match. But probably we have to wait till the last ball of the match. However, those overs are very much important for the two teams. It will be difficult to decide in the moment who will be the winner of the match.
Yes it seems that both Karachi kings and Quetta Gladiators will finish fifth and sixth position and therefore they will be eliminated from this tournament.
Check their performances and both of them have won a total of 3 matches of the 14 (8+6) matches they played. Karachi kings have played 8 matches and won only 2 of them. Similarly, Quetta Gladiators have played 6 matches and won only 1.
Do not think that now the remaining matches will be of no use as the top 4 teams would qualify. No, the position of the teams does matter as the team that finishes with 1st or 2nd position will get a double chance in the playoffs while the team ending up 3rd and 4th with play a knockout game.
