Are you the
Slow left arm wrist-spin bowling technique formerly known as Chinaman?
A part of me is famous for a drink,
Since we are talking about cricket, the drink is probably tea, which is a drink famously from China, and also served in china teacups. ("Punch bowl" also crossed my mind, but I liked the other one better)
I'll make the batsman out in a blink!
The chinaman spin is surprisingly strong, and in a surprising direction, so it's easy to miss altogether, resulting in the batsman instantly losing his wicket
Sometimes I may be equivalent to a wrong'un,
In cricket terminology, a "wrong'un" is a delivery that spins "the other way" than usual. A chinaman bowler is always left-handed, but the spin is like that of a right-handed spin bowler, so that probably counts.
