In the 4th Test against South Africa Tom Halsey took his first 10-wicket haul in Test cricket in his 9th Test. He now has 34 wickets in 9 Tests. The "number one" spinner in CWLand - Neil Pickup - took his first 10-wicket haul in the 3rd Test - his 54th. Pickup now has 217 wickets in 55 Tests.
Pickup now averages 30.41 in Tests.
Halsey averages 24.26.
The question is how strong Pickup's claim is to the number one spinner's spot, given the impressive returns of Halsey on the international stage.
