A Kevin Lisbie goal has given Leyton Orient a 1-0 lead over home side Tranmere Rovers in League One.
Orient went close in the opening minutes when Moses Odubajo broke through Tranmere's defence, but he could not control his shot and blasted wide.
Tranmere almost took the lead in the 20th minute when Danny Holmes found Max Power, who crashed his shot wide from 20 yards.
Rovers were made to pay minutes later as striker Lisbie finished neatly after great work from Lloyd James, who broke through Tranmere's midfield too easily.
Tranmere's Ash Taylor almost hit back as he headed a Chris Atkinson free kick towards goal, which required goalkeeper Jamie Jones to turn the ball onto the post to keep his side in the lead going into half time.
