Christian Stuani scored twice on his first Middlesbrough start as they beat Oldham 3-1 in the Capital One Cup first round.

There was early drama as Diego Fabbrini was brought down in the box by David Cornell. The goalkeeper made amends by saving Adam Clayton's penalty.

Boro did take the lead in the 23rd minute through Yanic Wildschut's low drive and doubled their advantage when Fabbrini crossed for Stuani to nod in.

Stuani doubled his tally with a close-range finish from James Husband's cross, before Danny Philliskirk grabbed an injury-time consolation for Oldham.

In a week littered with cup upsets, Championship team Boro were always in control against their League One opponents.

They missed a golden chance to go ahead on seven minutes as Fabbrini burst into the Oldham box and tried to round goalkeeper David Cornell, who brought him down to concede a penalty.

But Cornell, on his Oldham debut, made amends from Adam Clayton's spot-kick as he dived to his right and clawed the ball to safety.

Boro missed more early chances and their pressure told after 23 minutes when Albert Adomah's through-ball sent Wildschut racing behind the defence to slot home from 12 yards.

The lead was doubled on 41 minutes when Fabbrini showed pace and trickery down the left before crossing for Uruguay international striker Stuani to glance in and eight-yard header.

New signing Stuani killed off the home side after 61 minutes with a simple far post tap-in from James Husband's excellent low cross.

Oldham's consolation goal came deep in stoppage time when Lee Croft's ball from the left was headed in from eight yards by Philliskirk.
