Carlton Morris’s 20th goal of the season completed Luton’s comeback as they kept their momentum going with a 2-1 home win over Middlesbrough. The Hatters, unbeaten since mid-February, were a place above Boro in third going into the game and the winners knew that victory would keep alive their slim hopes of going up automatically to the Premier League at the expense of Sheffield United. It had looked like it would be the visitors after a dominant opening 45 minutes. They led through Cameron Archer, only for Town to fight back, strikes from Tom Lockyer and Morris’s penalty, claiming all three points, although Middlesbrough were left disappointed by the decision to award the spot-kick in the first place. Michael Carrick, the visitors’ manager, said: “A penalty like that, luckily we can laugh it off today in some ways, but I do wonder, with the referees being in the Premier League and then used to VAR and then not having it, I think it gives them a bit of insurance. “This is not directly to the referee tonight, it’s something in general to look at. Tonight didn’t count for too much in the end but it could be a crucial decision at some point. Whether it’s this season or next season, referees coming down it is very different when you haven’t got the security for the big, big decisions. I’m not moaning about tonight, it is what it is, it was never a penalty, of course it wasn’t, but it’s something to think about moving forward.” The visitors began impressively, Marc Bola firing well over the top from 25 yards. The Luton forward Elijah Adebayo tested Zack Steffen, the Manchester City loanee goalkeeper easily claiming his left-footed drive. Steffen’s opposite number, Ethan Horvath, was out well at the feet of Archer, while Michael Carrick’s side should have at least tested the USA international on 20 minutes, Isaiah Jones in acres of space on the right and picking out Matt Crooks who side-footed over the top. Boro took the lead five minutes before half-time with Archer racing on to Crooks’s pass over the top and beating the attempt of Horvath to clear, the keeper completely missing his kick and allowing the forward to take it round Sonny Bradley and walk the ball into the net. Luton came out for the second half a different side, though, and after forcing two quick corners they were level from the second just four minutes in, Alfie Doughty’s set piece met by Lockyer, who guided his header in via the the post. Boro might have led again after 55 minutes, Ryan Giles getting away on the left and his cross slammed wide by Crooks from 10 yards out. Doughty sent an ambitious volley way over from the angle of the penalty area but Town completed the turnaround after 67 minutes when the substitute Jordan Clark picked up a ball and sent Morris away. His first touch was not the greatest but he still got there ahead of Steffen, who clipped him for a spot-kick. It was Morris who assumed the responsibility, tucking away confidently into the bottom corner. Boro were not out of it as the dangerous Giles got away on the left but his cross was put wide by a stretching Bola. Luton then brought on the teenager Joe Johnson for his Championship debut for the final seven minutes and they managed to see out five minutes of stoppage time for victory. Luton, who have two games to play, are four points behind Sheffield United, who have two matches in hand. The Blades will be promoted with Burnley if they win any of their remaining fixtures, starting at home to West Brom on Wednesday. Luton, like Boro, are guaranteed a playoff spot.
