17 wickets fall on second day between Gloucs and Lancs

Rather ominously for Gloucestershire, Jennings looked well set and he drove Bell expansively through the covers to bring up the 50 partnership. Making his first appearance of the season, the tall left hander then guided a ball from Taylor through third man to register a chanceless half century from 87 balls via his seventh boundary.

Bohannon never looked truly secure in an innings that spanned 78 deliveries, Taylor bowling him for 21 with a yorker-length delivery that reduced the visitors to 120-2. Lancashire were in front soon afterwards, Marcus Harris stepping down the pitch and hoisting Graeme van Buuren over long-off for a huge six.

But Gloucestershire's slow left armer struck an important blow later in the same over, Jennings attempted to hit over the top, dragging the ball to Williams at mid-on and falling into the trap set for him.

Suddenly, Gloucestershire tails were up, and Taylor was rewarded for his persistence when Ollie Price took a fine catch low down at first slip to send back Michael Jones for a duck with the score 141-4.

When Bell trapped fellow Australian Harris in the crease for 12, Lancashire were 145-5 and under pressure, having lost four wickets in nine overs. Shetty was next to go, taking on Brookes and holing out to Boorman at deep square leg as Lancashire reached tea on 170-6.

That quickly became 180-8, Taylor having Balderson caught in the slips by Bancroft and then pinning Paul Coughlin in front to record his ninth first-class five-wicket haul.

Instead of running through the tail though, Gloucestershire were frustrated by a stubborn ninth-wicket stand of 58 between Matty Hurst and Ollie Sutton, a substitute for injured fast bowler Ajeet Singh Dale.

Hurst managed the tail-end resistance supremely well in a patient innings of 39 to extend Lancashire's lead to three figures as the bowlers tired. He was eventually bowled by Bell, while Taylor returned to remove Sutton for 19.

Lancashire finished the day well and truly on top, Balderson having Bancroft caught at the wicket, Anderson dismissing Price lbw and Coughlin persuading Ben Charlesworth to edge to second slip as Gloucestershire's top order floundered once more.

Miles Hammond and James Bracey reached the close without further mishap, but the home side will be required to muster a level of resistance beyond anything seen previously this season if they are to extricate themselves from a tricky situation.
