In the 43rd minute, Will Grigg found the space to turn and shoot home, then the second period was less than two minutes old when Lewis Morgan was first to a loose ball after Jack Bonham had saved well, prodding home to give the visitors a cushion they never surrendered.
The Rovers line-up included Stuart Sinclair, starting a game for the first time since New Year’s Day, in place of the cup-tied Abu Ogogo. Joe Partington was due to start the game at right back, but James Clarke was drafted in as a late replacement, leaving Rovers with just six substitutes.
Sunderland’s side had two differences to the one that won 2-0 at the Mem ten days previously. Lewis Morgan had replaced Duncan Watmore on Saturday, when the Black Cats beat Plymouth, and kept his place. He was joined by Max Power, who came in to the side in place of Lee Cattermole.
Sunderland reminded the Gas of their capabilities inside ten minutes, when Aiden McGeady curled from the edge of the box with a shot destined for the top corner before Jack Bonham, at full stretch, pushed the ball round. From the corner, Tom Flanagan headed not far over.
Rovers soon got into the game themselves, though, and after a fairly even opening 20 minutes, created a long spell of pressure which nearly told. After Sunderland only half cleared their lines twice, Liam Sercombe teed up Ollie Clarke to cross, and his dangerous low ball was deflected only just wide. Tom Lockyer’s header down from the corner was helped on by Tom Nichols, but caught by goalkeeper Jon McLaughlin.
Sunderland began to reassert, prodding and probing around the Rovers area, but the quartered shirts repelled those with stripes, and looked to hit on the counter-attack. From one break, Nichols tore down the right, and squared to Clarke-Harris, who helped on to Sinclair, advancing to his left. The dynamic midfielder looked to have squandered a chance when he cut inside on his right foot, but he stayed calm and set up Clarke-Harris. The forward’s shot was saved, but spilled, and Sinclair very nearly followed up.
Soon after, Clarke-Harris was fouled, and his quick-thinking led to him taking a free-kick quickly, setting Sercombe away, and his cross was again spilled by the edgy Sunderland goalkeeper.
Nichols went in to the book for one of those tackles that splits a crowd down the middle. He got the ball, but was it dangerous? The referee decided on reckless, and showed a yellow card.
Just two minutes before half-time, Sunderland produced the killer pass they had searched for 43 minutes. Max Power feigned to shoot but instead fed Will Grigg, who spun quickly in the area, and shot low past Bonham.
Rovers responded with a superb multi-man move, eventually working the ball wide to James Clarke, and his cross was only just stopped from reaching Clarke-Harris at point-blank range because of a superb intervention by Jimmy Dunne.
The start of the second half was palindromic of the first. Only 100 seconds had elapsed and Sunderland had scored what felt like a killer second. McGeady’s effort from the edge of the area was parried, but Morgan got to the loose ball first and was faced with a simple finish, which he took with relish.
Rovers’ response was almost perfect. A deflected shot led to a corner, from which Lockyer found acres of space, ten yards out. He could only his header over the bar – what a momentum switcher it could have been had he been more clinical.
Sunderland looked for a third to ut Rovers totally beyond reach. Max Power hit a shot with…well, a lot of power, which Bonham shovelled away, and Morgan tried his luck from distance too, only to find Bonham’s arms.
At the other end, Rovers kept pushing. A smart incursion by Holmes-Dennis ended in McLaughlin saved well at his near post. This led to three consecutive corners, the second of which nearly yielded a goal, as James Clarke stole in at the near post but his flick was deflected wide.
With 20 minutes remaining, Graham Coughlan opted for a three-pronged change to try to get back in the game. Chris Lines, Alex Jakubiak and Michael Kelly came on, replacing Sinclair, Nichols and Ollie Clarke, with Rovers switching to a more orthodox 4-4-2 to try and utilise the width of the Mem.
Thanks largely to good game management by Sunderland, Rovers could not get a foothold in the tie. A corner or two cannoned around the area, and a cross or two looked promising before getting ejected from danger.
Congratulations to Sunderland, who we wish well in the final. For the Gas, attention can be entirely focused on the important business of staying in Sky Bet League One.
