The match between Peshawar Zalmi and Quetta Gladiator is being held at the moment. And Peshawre has collected only 67 runs in 10 overs, by losing only 2 wickets. I bet on the victory of Quetta Gladiators in this match.
Interest is there. But since the tournament was suspended mid-way, and then resumed after a few months, it will take some time to build the momentum. Also, some of the big names have pulled out of the PSL (Rashid Khan, David Wiese, Alex Hales, Chris Lynn, Tom Banton, Liam Livingstone.etc). They are either participating in international duty, or playing in the Vitality T20 Blast in England. But I can say that there is interest from India. The matches are being shown in Ten Sports and a lot of cricket fans are watching them.
