I won't call Quetta Gladiators' batting performance bad, I would put their poor bowling performance as the reason behind today's loss, although they took 2 wickets more than Peshawar Zalmi but they were very expansive in terms of runs and that was the reason for their loss.
For Quetta Gladiators, Naseem Shah and Mohammad Hasnain bowled their hearts out. These two had combined figures of 8-1-32-3. The problem is that they received zero support from the other players. For the rest, bowling figures are: 10.3-0-125-3. The spinners (Mohammad Nawaz and Qais Ahmad) failed to block the flow of runs in the middle overs. And that is the reason why Zalmi won, despite losing wickets at regular intervals. Quetta got the worst possible start to their season. They have played three matches, and won just one against the Karachi Kings.
And now if we talk about today's match then Quetta gladiators and Lahore qalandars both team conditions is nearly same . But even then I will choose Lahore qalandars in the win probability.
