Robert Key ranked his match-winning 93 at Old Trafford above his double century in the opening match of the series against West Indies.
Key shared an unbroken stand of 120 with Andrew Flintoff to seal victory.
"To get 200 is a great feeling but that was even better, especially to do it with Freddie, who's a great friend," said Key after the seven-wicket win.
"It was hard work but we managed to get through, had a bit of luck, and the wicket got pretty good at the end."
Of a battling 84-run stand with captain Michael Vaughan he said: "I tried to blank everything out and get through the first hour and I surprised myself to end up [still in] at the end."
Vaughan was full of praise for Key, but paid triubute to a West Indies side that showed far more fight in the third match of the series than they had in the opening exchanges.
"We knew that one player had to get in and see us home and Rob's done that fantastically," said Vaughan.
"But you've got to give West Indies credit for the way they played in this Test match.
"They put us under a lot of pressure and to be honest we didn't play that well.
"In the last two days we showed a lot of fighting spirit - to come out and bowl them out then fight those runs down today is a great testimony to the team."
