Cheteshwar Pujara, an expert in Test cricket for India, scored his third century in the Royal London One-Day Cup on Tuesday.
Pujara, playing for Sussex, smashed 132 off 90 balls to assist his team in reaching 400 for 4 against Middlesex in 50 overs.
His offensive knock contained 20 fours and a few sixes.
Tom Alsop, who started the game, led the scoring with 189 off 155 balls.
