Yup I thought that Zimbabwe had their chances in this match specially when they were chasing the 298 runs. First they gave away too many runs as they could not take wickets in the dept when J Liyanage made 70 not out in only 47 balls and also Mendis made 57 runs and that was another fast innings.
While battling there were some great innings by Sikandar Raza and BJ Curran but no runs by one of the opener and BRM Taylor made the chase difficult and in the end they lost this game.
Actually, Zimbabwe could have won this match only if Zimbabwe had not lost their batsman Sikandar Raza, but unfortunately Sikandar Raza was dismissed after scoring 92. After his dismissal, Zimbabwe came under some pressure and at this time Tony Munyonga wasted some valuable balls with dots, which ultimately led to their defeat in the last over.
I think he was playing fewer big shots to complete his half-century, which is something that a responsible player should not have done at that time because in T20s, even if there was a possibility of wickets going down at this time, he should have played big shots.
