Barnsley's Jack Shepherd saw red after just nine minutes before Vimal Yoganathan put the hosts ahead.

Mark Harris drew Oxford level in the second half but the U's were not able to complete the comeback.

With two minutes left on the clock, Jamie Cumming was sent off for a challenge well outside of his penalty area.

Here is how we rated the Yellows on a disappointing afternoon...

Jamie Cumming - 4.5

Big save in the second half moments before getting sent off.

Did not look like there was much wrong with the tackle other than perhaps excessive force, but did he even need to come for the ball in the first place?

Brodie Spencer - 5

Lost possession 10 times in the first half and was booked after 11 minutes.

Michal Helik - 6

Eight defensive contributions and comfortable on the ball, helping pin Barnsley into their own third.

Had one header blocked from a corner.

Sam Long - 6

A mixed bag for Long who looked like a safe pair of hands until a big error in his own box.

Then played a lovely ball which led to the equaliser.

Jack Currie - 6

Created one big chance and offered a threat on the overlap.

Kai Andrews - 5.5

Three key passes and saw four shots blocked, all from outside the box.

Louie Sibley - 7

Beat Shepherd to the ball which resulted in the red card.

Some moments of neat footwork, worked hard to win the ball back and created one big chance with four key passes.

Luka Lynch - 5.5

Did not have as much joy on the right as his replacement Aidomo Emakhu.

Did not threaten enough, finding it hard to get into the box.

Tyler Goodrham - 6.5

A bit lightweight at times, but thought he offered a lot at Oakwell.

Five key passes and one big chance created whilst also rattling the crossbar with a great strike in the second half.

Found some good areas in the box in the first half but had one pass to Harris in space go begging in the second.

Siriki Dembele - 5.5

A dipping shot came close after putting one wide early on but did not offer much threat out wide.

Mark Harris - 7

A goal similar to that against Stockport, working a yard in the box to sweep home.

Two goals in two matches for the Wales international with five shots against the Tykes which all came fairly close.

Substitutes:

Peter Kioso (46') - 6.5

Worked well with Emakhu on the right and had a shot cleared off the line.

Aidomo Emakhu (46') - 7

Added directness and trickery to the right wing, assisting the goal.

Kept persisting and had a great effort saved impressively.

Gatlin O'Donkor (57') - 6

Mo Missanga (77') - N/A

Simon Eastwood (89') - N/A
