Dillon Pennington claimed a five-wicket haul before unbeaten twin fifties for Joe Clarke and Jack Haynes helped Nottinghamshire seize the initiative on day two against Somerset in Taunton.

Pennington returned figures of 5/65 from 26.5 overs, taking all four wickets to fall on the second morning, as the hosts were bowled out for 347.

Clarke and Haynes then picked up the mantle, striking 70 and 53 respectively in an unbroken stand ultimately worth 90 by the end of the day, as the Green and Golds closed on 218-3, in arrears by 129.

The first half of the day, however, very much belonged to Pennington, as Somerset, resuming on their overnight 292-6, added only 55 further runs before their innings was wrapped up.

Jack Leach miscued to Ben Slater in the covers after only 15 minutes, before Migael Pretorius heaved at a straight one and became Pennington’s second victim of the day.

Both of those two batters had made 11, and both of the next pair to go hit two each, with Alfie Ogborne chopping on before Jake Ball was impressively caught by Haynes at third slip.

Ogborne’s dismissal saw Notts secure maximum bowling bonus points, but it was Ball’s wicket that proved more consequential, wrapping up the innings and handing Pennington his five.

Buoyed by a plan coming together, Green and Gold openers Haseeb Hameed and Ben Slater set off assertedly, reaching 36 without loss at lunch and extending their stand to 59 afterwards.

Both fell to Pretorius in quick succession in the early afternoon with the floodlights turned up, but new pair Clarke and Freddie McCann survived through to tea after taking the score into three figures.

Pretorius did remove McCann for 31 early on in what was intended to be an extended evening session, but that only brought Haynes out to join Clarke.

Both went to their fifties after a first brief stoppage for bad light, with Clarke doing so first from 99 balls, before Haynes followed shortly afterwards off 76.

Although the duo had batted patiently for the most part, reaching their fifties allowed them more freedom to unfurl, and they continued to slash the Somerset lead by moving past 200.

It was unfortunate timing, therefore, that bad light again intervened to end the day early for the second time in succession.

Ball had seen an over go for 13, and Leach added to that by conceding seven, as Clarke and Haynes batted with increasing confidence, only for play to conclude 13 overs short of the allotted amount.
