5. Ajay Sharma:

His average in domestic cricket was 67.46, which was the third-highest in the all-time list. He got an opportunity to play for India, precisely for this reason. For some reason or the other, he played only a lone Test match and has, however, starred in 31 ODIs.
This stroke maker from Delhi hardly lived up to expectations as he could make only 424 runs out of the total ODIs played by him. He was the biggest disappointment, having achieved virtually nothing like an international batsman.
