New Zealand retiring skipper Brendon McCullum has insisted that he is committed to remain at the top of his game in the upcoming ODI series against Sri Lanka.
The 34-year-old swashbuckling opener said that his side had got a bumper calendar with Sri Lanka, adding that he would try to make maximum contribution towards his side in the forthcoming series, Sport24 reported.
Earlier, McCullum had announced that he would retire from all forms of international cricket in February next year.
McCullum, who recently bagged the ICC Spirit of Cricket award, will play his 100th Test against Australia in Wellington from February 12 and will retire after the second and final Test of that series, in Christchurch from February 20.
Meanwhile, New Zealand, who clinched the two-match Test series 2-0 against Sri Lanka, will now play in the five-match ODI series, starting from Saturday at the Hagley Oval.
