Match ends, Leyton Orient 0, Barnsley 0.
Leyton Orient 0-0 Barnsley
Barnsley goalkeeper Adam Davies pulled off a number of good saves as the Tykes extended their League One unbeaten run to seven games at Leyton Orient.
Jobi McAnuff's shot was well saved by Davies and team-mates Chris Dagnall and Darius Henderson also went close.
Davies then denied Ryan Hedges from close-range after the break.
Conor Hourihane's 20-yard free-kick was the closest Barnsley came to a goal as his side played out stoppage time with 10 men after Milan Lalkovic's red card.
Sub Lalkovic was sent off for a two-footed tackle on Nathan Clarke, as Orient dropped a place to 22nd in League One, three points from safety, while Barnsley still occupy the final play-off place.
Leyton Orient manager Fabio Liverani told BBC London 94.9:
"It was a big match. The performance was very good and I am happy for my team.
"We lacked precision and were not clinical in front of goal. The Barnsley goalkeeper is very good, but we had big chances and should have scored.
"It is a very balanced league. All games are important, but I trust in my team."
