Few players are more worthy of a chance to showcase their talents at a higher level, with Bates having been a stalwart at provincial level for years. He was the winner of the 2009-10 overall domestic MVP and has a knack for bowling convincing spells at the death to help Auckland excel in recent seasons.
Bates benefited from learning off New Zealand bowlers like Andre Adams, Kyle Mills, Chris Martin and Daryl Tuffey in the Auckland squad after debuting in 2003-04. He has taken on more responsibility in recent seasons with the various absences of that quartet.
In contrast, Nethula is viewed as a reinforcement and possible long-term replacement for Daniel Vettori in tests, overleaping Jeetan Patel in the reckoning. Tomorrow's ODI represents a chance on an insulated 10-over scale to see whether the Central Districts leg-spinner's rip passes muster, given a test spin bowling succession plan is one of New Zealand's biggest medium-term problems.
Nethula has taken 16 wickets at an average of 19.62 in the Plunket Shield. He generates plenty of top and side spin but, like many leg-spinners, can be vulnerable to inconsistency in his efforts to get more revolutions on the ball.
Patience, tenacity and attack tend to be a leg spinner's watchwords - not an ideal marriage in the limited overs game - but given stand-in captain Brendon McCullum's penchant for aggression Nethula will know he should get a decent chance to present his case. If successful, Nethula will be a candidate to get a test run later in the summer against South Africa and during the year on spin conducive pitches in the West Indies, India and Sri Lanka.
