1937 saw Glamorgan record two comprehensive victories over the New Zealand tourists. The first victory at the Arms Park saw Dick Duckfield compile an attractive century and off-spinner Closs Jones take 10/94 as the Welsh county won by six wickets. The second match at Swansea resulted in Glamorgan recording one of the most emphatic victories in their first-class history.

Seventeen wickets fell on the first day as Glamorgan were indebted to Emrys Davies for a fighting innings of 58 against the accurate Kiwi bowlers, supported by lively fielding, dismissed the Welsh side for 229. This was well short of what Maurice Turnbull had envisaged on what appeared to be a true Swansea wicket, but his new ball bowlers soon put Glamorgan back into the match. In particular, Austin Matthews caused the tourists problems with his lively seam bowling. He reduced the tourists to 21-3, before the left arm spin of Emrys Davies made short work of their lower order, taking 4/16 as New Zealand subsided to 127 with several of their batsmen falling to reckless strokes.

This turned out to be a fine match for Emrys Davies, as the experienced all-rounder shared in an opening partnership of 157 with Arnold Dyson to put Glamorgan into a commanding position. However, it was left to Cyril Smart to put the game out of the tourist`s reach, hitting three sixes and ten fours in a brisk innings which guided Glamorgan into an overall lead of 442.

By the final morning of the game, the Swansea wicket was responding more and more to spin bowling, and who better to exploit the turning surface than Johnnie Clay. The veteran off-spinner took 5/27 as the tourists stumbled to 89-8, and the vocal Glamorgan supporters started to clear their throats in anticipation of an overwhelming victory.

The final rites were delivered fittingly by Emrys Davies who took 5/30 as Glamorgan won by 332 runs. This still remains the club`s largest ever winning margin, and at the time it was clear proof that the club, under Maurice Turnbull`s inspirational leadership, had made huge forward strides. It was their tenth victory of the summer – the most they had ever recorded – whilst Clay`s bowling took his tally for the season to 141.
