Nya Kirby put Palace in front from the penalty spot on 27 minutes, but Rumarn Burrell continued his hot goal-scoring form as he equalised just before the break. 

Boro had already sealed a place in the knockout stages of the competition in the penultimate Premier League Cup outing by beating Blackburn Rovers 4-1. 

The first chance fell to Boro captain Tyrone O'Neill with just over ten minutes played, as he spun away from a Palace defender on the edge of the box but his attempt was off target. 

Heavy rain and strong winds played their part throughout with passes from both sides going astray, and it almost came to Boro's aid when an in-swinging Jack Robinson corner heading for the back post had to be tipped away by Eagles stopper Jacob Russell. 

Despite having the majority of possession, the hosts were behind just before the half hour mark as Brandon Aveiro started the counter attack in his own half to the Boro Box and David Boateng was pushed inside the penalty area, leaving the referee no option other than to point to the spot.

Kirby dispatched from 12 yards as he slotted it into the bottom right corner, sending Dejan Stojanovic the wrong way. 

Graeme Lee's side almost got back on terms only a few minutes after going behind as Sam Folarin unleashed a curling strike from the left side of the box, which Russell could only punch clear for a corner. 

Boro continued to press for a leveller, and O'Neill tried with two efforts, with his dipping volley on the edge of the box only just looping over the top of the crossbar before firing a powerful strike from 30 yards which was also over. 

Russell was equal to another effort from range by O'Neill, palming away his strike from a corner which Boro would profit from - Burrell meeting it from close range. 

Opportunities were limited in the opening exchanges of the second half, and Folarin's shot from outside the area did little to trouble Russell. 

Nathan Dale was inches away from giving Boro the advantage for the first time with 64 minutes gone on the clock as he took aim with a low drive that was just wide. 

Stojanovic was rarely tested throughout between the posts for Boro, but he had to push a well-struck attempt from range from Aveiro over his bar in the closing stages, before a sweeping strike fizzed just wide from the Palace number seven in stoppage time.
