Preamble Good day. It's gonna be a good day today. I don't know about you, but I've been unable to sit still all morning, a bairn impatiently waiting for play to start. There are approximately 160 days of Test cricket each year. Plenty are compelling; a few are mediocre; one or two build a four-bedroom semi with all mod cons in the memory bank. Today could well be one of those days. South Africa will resume on 145 for three, a lead of 139; a Test of rare intensity and importance is crescendoing beautifully. Can anyone score me some beta-blockers please? Valium? A hot toddy?
