Much dust

Lunch: Yorkshire 374 for 2 (122 overs). Sayers 149, McGrath 122.

The 250 partnership came up from 471 balls just before lunch. Warwickshire have persevered innocuously to increasingly defensive fields.

These batsmen are on the threshold of history. Yorkshire's record third-wicket stand against the Bears is 258 by JT Brown senior and F Mitchell at Bradford in 1901.

Much dust is blowing across the ground as the groundstaff wield their brooms on this dry, brown pitch.
