I was surprised they chose it over Park Avenue and Sheffield, but it is a lovely ground. Not sure the wicket is really "first class" though...
They've had the Diamonds there in the last couple of years, some T20 warm up games and some 2nd team games. It is also where they train a some of the time too.
Top facilities too since the clubhouse was rebuilt.
Will be interesting to see how the track plays for them over 4 days, it's generally quite a road or always used to be.
