AB de Villiers was delighted to have contributed at a crucial time to guide South Africa to a series victory in the fifth one-day international with England.
Playing in his 200th ODI, De Villiers looked back to his destructive best in Cape Town as he blasted 11 fours and one six on his way to 101 not out from 97 deliveries.
The Proteas' skipper has struggled for runs in the series so far with 73 in Port Elizabeth the only score of note before his 24th ODI century on Sunday.
His unbeaten innings was key as South Africa claimed a five-wicket win at Newlands, completing a comeback from 2-0 down in the series.
"I've been a bit off my game in the last month or so, so it's nice to finish like that," De Villiers said at the post-match presentation.
"It's an integral part of being a captain, you've got to lead from the front, you can't just chip in with small performances.
"I didn't think we were that far off in the first two ODIs so the belief was still there, we just had to find a little bit of confidence and that's where things turned around."
Meanwhile, England skipper Eoin Morgan rued another lacklustre display from his side, the tourists' batsmen struggling as they could only post 236 - a total South Africa chased down with six overs to spare.
He told Sky Sports: "I don't think we did enough, we were outplayed here today. We did have chances in previous games to wrap up the series but we weren't good enough.
"The opportunities would have been executed if we had more experience in the side, but we're growing and learning.
"We pushed them so hard even though we underperformed, we started with the ball exceptionally well, but it just wasn't enough."
