As usual, Lancashire had brought a strong side but the home team was bolstered by the inclusion of both Andrew Gale and Tim Bresnan.
Yorkshire made two early breakthroughs as Oliver Robinson trapped Alex Davies with a long-hop, which Davies obligingly pulled to Eliot Callis at midwicket. That was 27/1 and, some 20 runs later, Karl Brown pulled a Moin Ashraf bouncer into the grateful hands of Will Rhodes who did not have to move at deep square leg, where he had been placed for exactly that shot.
But that only brought Jordan Clark out to partner Steven Croft and the pair took the total to 147/2 at lunch from 38 overs, an unbroken partnership of exactly 100. The Yorkshire spinners had been both ineffective and expensive and the post-lunch session looked like it was going to be a long slog for the seamers.
How wrong can you be ! The next two hours and twenty minutes saw those White Rose seamers turn in collectively one of the best displays of the season and Moin Ashraf led the way with a splendid return of 14-5-25-4, finding movement and bounce to disconcert all the opposition batsmen. Tim Bresnan chipped in with 13-7-17-2 and worked up some pace and bowled a full length as he searched for full fitness.
Oliver Robinson took another wicket and the persevering Karl Carver wheedled out Tom Bailey. In all, Yorkshire conceded 75 runs in the afternoon session from 40 overs but took eight wickets. It would have been even better if Gavin Griffiths and Adnan Ghaus had not added a spirited 34 for the last wicket.
This left Yorkshire with 25 overs to bat and they lost Callis almost immediately as he nicked one to Jordan Clark at third slip. But enter Andrew Gale and he and Jonathan Tattersall took the game into the final over of the day before Gale edged to keep Alex Davies who took a good tumbling catch. Tattersall survived on 24 in exactly 100 minutes at the crease.
