Play-off finals from Sky Sports Vault: Leyton Orient 2-2 Rotherham (3-4 on pens), 2014

Ahead of play-off final weekend, we dig into the Sky Sports Vault to look back at a classic from 2014, when Rotherham beat Leyton Orient.

Rotherham earned promotion after beating Leyton Orient 4-3 on penalties in the League One play-off final at Wembley after a 2-2 draw.

Both sides missed one of their first four penalties before Richard Smallwood put Rotherham 4-3 ahead. That meant Orient's Chris Dagnall had to score but his spot-kick was saved by Rotherham goalkeeper Adam Collin, earning the club promotion to the Championship.

Orient had gone 2-0 up after first-half goals from Moses Odubajo and Dean Cox, but Rotherham's Alex Revell netted a second-half brace against his former club as the match went to extra-time and then spot-kicks.

There was more disappointment for Orient 12 months later, finishing 23rd in League One as they were relegated to the fourth tier.

Rotherham, meanwhile, stayed in the Championship by the skin of their teeth in 2015, before staying up in 21st place once more in May 2016.
