Why? Surely this is anachronistic?
In a batsmen's world of bigger bats, shorter boundaries and limited-overs bowling restrictions, Jan's sleight of hand is just what the sport needs to add an element of surprise.
Batsmen can switch-hit at will, without fear of reprisal through a reversal of the lbw law. Their ability to adapt unexpectedly is celebrated. Likewise, bowlers should have ambidextrism as a means of counterattack in their repertoire.
Jan runs to the crease with the ball in one hand and switches grips as he approaches his delivery stride. A natural right-armer by birth, he has worked on his party-trick since childhood.
Such prodigies, particularly in the spin world, have emerged before, but no one has sustained the practice.
Until he was discovered by former Pakistan pace bowler Aaqib Javed in a nationwide talent hunt, Jan worked with his brothers in his family's vegetable shop. Aaqib has form for talent-spotting, too. He is the man who brought 2.16m Mohammad Irfan to the international stage.
Jan has been signed on a 10-year developmental contract by the Lahore Qalandars franchise in the Pakistan Super League. He is expected to be ready to play top-level cricket in a year. Like all pioneers, the cricket world would be better for seeing his rare skill flourish.
In the meantime, he could come under the mentoring of Brendon McCullum in the practice nets. The former New Zealand captain is expected to be signed as the franchise's captain at the October 19 player auction in Dubai.
