He was the leading wicket taker in the 2007–08 Carib Beer Challenge and in June 2008 he won his first One Day International cap with the West Indies.
The following year he made his Test debut for a weakened West Indies team during a contract dispute.
As of June 2013, Miller boasted the lowest First Class bowling average (15.51) of any active player in world cricket.
Despite this, he has been overlooked for West Indies selection in favour of other spinners Devendra Bishoo (FC Ave: 29.77), Sulieman Benn (27.58) and Veerasammy Permaul (24.36).
[1][5] In the final game of the regular season he took seven wickets against the Windward Islands, including 406 in one innings, as Jamaica won to win the league.
"I was looking out for it [earlier] because I had a good season so I always kept my mind in tune for that call so that I won't be surprised," said Miller.
[11] Mill made his West Indian debut on 4 July 2008, his first international wicket coming when he dismissed Michael Clarke lbw.
He was part of an understrength team fielded by the West Indies against Bangladesh; the 15-man squad included nine uncapped players.
Including Miller, seven West Indies players made their debut and the side was captained by Floyd Reifer who had played the last of his four Tests ten years earlier.
The first XI had made themselves unavailable due to a pay dispute with the West Indies Cricket Board.
In one day cricket he took 4–47 against Zimbabwe helping the West Indies to a rare series win,[19] and 3–15 against Canada.
He played for West Indies A against Sri Lanka A, scoring 6-141 and making 50 not out in one game, and taking 6-51 and 2–23 in the one dayers.
In November 2016 during the 2016–17 Regional Four Day Competition, he took 5–22 against the Windward Islands, helping Jamaica to a narrow victory.
"The one thing I'd say about criticism of whether I could replicate my domestic performances at Test level, and can only speak for myself – I have played in A team cricket in 2013 versus India and Sri Lanka, playing against guys like [Virender] Sehwag, [Gautam] Gambhir, [Cheteshwar] Pujara, Yuvraj [Singh] and got five-wicket hauls and was the leading West Indies A wicket-taker.
Miller had been overlooked in favour of Shane Shillingford, Devendra Bishoo, Sunil Narine, Veerasammy Permaul and Jomel Warrican.
There are times when he may rub authorities the wrong way with his willingness to speak up, but others have played far more often for the West Indies with far greater baggage on their resume.
