Essex 377 (Westley 81, Elgar 79, Khushi 53) beat Lancashire 146 (Snater 4-42) and 107 (Snater 3-17, Porter 3-24) by an innings and 124 runs

Porter set the ball rolling with the first of nine Lancashire wickets to fall in the session to finish with 3 for 24 before Snater took his match figures to 7 for 59 with 3 for 17 in the second innings. Essex's second win of the season, worth 22 points, took them further clear at the top of the Vitality County Championship with only three games played.

"We have started the season fantastically well," Essex captain Tom Westley said. "Even that last game against Kent we were a bit unlucky with the weather so potentially, it could have been three wins from three.

"We've been successful for a while now as a club so every game is a big game and we look to win every single game. We've just played some fantastic cricket and I think this is one of our better, most complete performances.

"I thought the bowlers bowled amazingly well and I think our challenge is to maintain this momentum and keep the standards as high as they currently are.

"We know what a good side Lancashire are, they are always identified at the start of the year as contenders to win the division. So to control the game and win every session is a huge pat on the back for Essex."

Lancashire had started day three on 10 for 1 and requiring another 221 runs to make Essex bat again. They lost five wickets in the first hour and never recovered with the game wrapped up in extra time before the scheduled lunch interval.

Essex were forced to field 19-year-old Ronnie McKenna as substitute behind the stumps when Michael Pepper pulled out with a finger injury suffered the night before. The Basildon-born 2nd XI wicketkeeper, the third to do the job for Essex in three Championship matches this season, had four leg byes sail past him down the leg side in the first over from Cook.

However, 11 balls into his first-team appearance, he was celebrating a first significant contribution as nightwatcher Will Williams edged Porter into his gloves having hung around for 36 balls.

That precipitated a catastrophic collapse with four wickets falling in 16 balls. Josh Bohannon lasted 25 balls before he walked across a delivery from Cook and was lbw, while Luke Wells was beaten all ends up by Snater to be bowled for a 54-ball 21. In the same Snater over George Balderson saw the umpire's finger go up as he played down the wrong line before Tom Bruce had his off stump sent cartwheeling by Porter.

There was a 10-over hiatus while Matty Hurst and George Bell put on 30 runs before the wicketkeeper scooped Snater into square leg's hands.

Offspinner Simon Harmer had not bowled much on this seamer's paradise, but in his fourth over of the innings he had Tom Bailey walking down the wicket and patting the ball back for a simple caught and bowled. Next over Jack Blatherwick followed Bailey's lead and gave Harmer more catching practice by chipping the ball back to the bowler.

Bell had hung around for 40 balls and appeared to be heading for a third fifty in four innings at Chelmsford when he nicked Cook to Dean Elgar at first slip to wrap up the match.
