Australia spinner Ashton Agar mentioned that Bangladesh pacer Mustafizur Rahman's skill set is incredible and admitted having immense difficulty in picking up the slower balls of the left-arm paceman.

"Man, he is a difficult customer," is how Agar reacted when asked about Mustafizur during a press conference today.  

"He is really good. His ability to bowl that slower ball [is very good]. If you watch it in slow motion, [you will see] he pretty much does it with his wrist and his fingers. It's incredible, incredible skill. Amazing revolution," added Agar. 

Mustafizur was pivotal in helping Bangladesh restrict Australia to a sub-par 121 for seven yesterday and eventually win the second T20I by five-wicket. The ace-left arm paceman remained the pick of the bowlers for the Tigers with his figures of three for 23 in four overs.

He first had Australia opener Josh Philippe fooled with a trademark Mustafizur slower delivery. Philippe totally misread the pace and length of the ball as he moved across the stumps to play on the leg side but only saw his leg stump take flight. 

Mustafizur then removed Australia skipper Matthew Wade almost in a similar fashion before deceiving Agar with a slower bouncer that took the left-handed batter completely by surprise, leading him to edge it back to the wicketkeeper.

And unsurprisingly, Agar, who was Mustafizur's last victim in yesterday's game, was left stunned by the amount of variation the left-arm seamer is able to bring into his game.  

"It's a great slower ball as well because it's not too slow and It's got a lot of revolution. It might kick quite a bit off the surface, it might go low, might not or it might spin a lot. It's super variable. And he gives himself that opportunity to put [variations] as much as he can on the ball," said Agar. 

Mustafizur was also instrumental in the Tigers' first T20I victory over the Aussies on Tuesday as he scalped two wickets for just 16 runs in four overs in that game.
