Bolton Wanderers suffered a heavy defeat in London as Leyton Orient put four past them at the Breyer Group Stadium.
Although Billy Crellin made a penalty save inside the first 30 seconds, Wanderers succumbed to three first half goals when Danny Johnson, Jobi McAnuff and Connor Wilkinson struck.
A fourth from Craig Clay in the second half ensured Orient ran out comprehensive winners.
Ian Evatt named an unchanged side from the team that picked up a midweek victory against Bradford City at the University of Bolton Stadium.
Tom White was named among the substitutes after recovering from the knee injury which he sustained against Shrewsbury Town in the Papa John’s Trophy earlier in the month.
Wanderers got off to a somewhat bizarre start when after barley 20 seconds they had conceded a penalty. Alex Baptiste’s back pass was intercepted by Danny Johnson and as the Orient striker was about to round Billy Crellin, the Wanderers keeper upended him for a penalty.
Crellin, who had saved a penalty in midweek, repeated the feat as he denied Johnson, who had picked himself up to take the spot kick, by diving to his left.
In the fifth minute, Ali Crawford put a ball over the top for Arthur Gnahoua to latch on to, he managed to round Lawrence Vigouroux, but his flick lacked the direction and pace to land in the Orient net before it was cleared to safety.
Johnson atoned for his earlier miss when he slotted home from close range after getting in front of his marker to convert a left-sided cross from James Brophy.
Harry Brockbank spurned a good chance to equalise when he got on the end of a low cross from D0elfouneso. The wing-back’s header bounced off the ground and went over the bar. In fairness, it was a difficult chance with the ball coming at an awkward height for him.
The visitors suffered a further blow when they lost Delfouneso through injury midway through the first half. Ronan Darcy came on in his place as they were looking to snatch a quick equaliser.
Peter Kioso volleyed from a tight angle to hit the side-netting after Wanderers broke into the Orient third looking to get back into the game.
Ryan Delaney cleared off his own goalline after Crellin spilled Jobi McAnuff’s cross.
Andrew Tutte blasted high and wide after Crawford’s free-kick was taken short and found his fellow midfielder deep and in space.
Wanderers were making slight in-roads and Ricardo Almeida Santos’ clever ball found Antoni Sarcevic who took a touch and advanced into the box. His drag back narrowly failed to find Gnahoua who was well-placed.
Former Wanderers forward Wilkinson was fouled by Tutte 25 yards from goal and McAnuff curled in the resulting free-kick into the top right hand corner to give Crellin no chance.
Wilkinson made it three a couple of minutes later when his left-footed free-kick sneaked in the bottom corner after Almeida Santos had fouled him.
Evatt made a double change at the break, bringing on White and Gordon for Tutte and Baptiste respectively.
Crellin saved McAnuff’s free-kick five minutes after the restart after Santos was penalised for holding on to Johnson.
Clay made it four just before the hour mark curling in a right-footer from distance beyond Crellin.
Gordon headed wide from a deep Kioso cross as Wanderers looked for a consolation goal.
A cross from the right by Kioso found Crawford in space, but the Scot’s first-time effort was blocked at the expense of a corner.
Vigouroux made a theatrical save to keep out a curling effort from Craword with just under ten minutes of the game remaining.
Wanderers huffed and puffed in an attempt to find a way through the Orient defence, but they couldn't work their way back into the game and ultimately were heavily beaten in the capital.
