Middlesbrough claimed their first win at the King Power Stadium with a 2-1 victory over Championship leaders Leicester. After the hosts missed two big chances to take the lead, Finn Azaz opened the scoring in the 24th minute with a clever finish from Lewis O’Brien’s square pass before Samuel Silvera’s emphatic strike after 37 minutes extended Boro’s advantage. Jamie Vardy halved the deficit in the 85th minute, but Middlesbrough held on to end a four-game winless run and complete the double over Leicester. The Foxes, who lost at home for the first time since November, are now nine points in front of second-placed Leeds – their opponents on Friday. Leeds kept up the pressure with what their manager, Daniel Farke, called a “mature” display in a comfortable 2-0 win at Plymouth. The victory came thanks to goals from Wilfried Gnonto and Georginio Rutter. “The Championship is relentless,” said Farke. “We must not forget we have one of the youngest sides in the division, especially near the top, so they have shown a lot of maturity. It’s all about consistency, which is what we are showing.” Ipswich kept up their push for an automatic promotion place as Conor Chaplin claimed a landmark winner in a 2-1 victory at Swansea. Chaplin scored his 50th Ipswich goal to restore a first-half lead that had been wiped out by Jerry Yates four minutes earlier. Nathan Broadhead had put Ipswich ahead. Coventry kept themselves in the playoff places with a hard-fought 1-0 win away at Stoke. Ellis Simms’ third goal in five games secured all three points for Mark Robins’ team, consolidating their sixth-place standing on goal difference. Defeat for Stoke means they have now lost five of their last six matches, leaving them just three points clear of the relegation zone. Norwich reeled off their fourth straight home win as they cruised past Cardiff 4-1 to maintain their playoff push. Jamilu Collins fired Cardiff ahead after 19 minutes against the run of play, but the hosts were in front by half-time thanks to two goals in five minutes from Josh Sargent and Gabriel Sara. Sargent went on to add his 10th of the season after the break, with a fourth from the substitute Christian Fassnacht completing a comfy win. The Hull captain, Jacob Greaves, snatched a dramatic stoppage-time winner as his side kept pace in the playoff race with a 2-1 victory at Huddersfield. Greaves had put Hull ahead in the seventh minute and, after Jack Rudoni had seemingly earned the home side a point in added time, netted a diving header in the dying stages to earn victory. Back-to-back wins following a disappointing home defeat by Swansea have left Liam Rosenior’s side out of the top six only on goal difference while Huddersfield lie two points above the relegation zone. John Eustace’s wait for a first win at Blackburn goes on after Preston battled back to claim a 2-2 draw at Deepdale. Eustace, whose first game in charge ended in defeat at former club Birmingham, saw his side let a 2-0 lead slip but still dented Preston’s playoff hopes. All four goals came in the first half as Sammie Szmodics regained his place as the division’s top scorer before Sam Gallagher doubled the visitors’ lead. But Robbie Brady’s 39th-minute strike and Emil Riis’s effort four minutes later secured Ryan Lowe’s hosts a point. Tony Mowbray celebrated back-to-back home wins against his most recent former clubs after Birmingham came from behind to beat Sunderland 2-1. Koji Miyoshi capped a magnificent comeback by City after Jordan James equalised on the hour to make it two home victories in five days after they beat Blackburn 1-0 on Tuesday night. Jack Clarke had given Sunderland the lead in the 22nd minute with his 15th goal of the season. Watford gave their season a much-needed boost with a 1-0 win at struggling Rotherham. Both teams went into the fixture out of form and on the back of three straight defeats but Yáser Asprilla’s second-half winner gave Valérien Ismaël team a lift – though they were clinging on by the end. Ilias Chair’s first-half goal boosted QPR’s survival chances with a 1-0 win over Bristol City at Ashton Gate. The key moment came three minutes before half-time when Lucas Andersen’s low cross from the right was stroked home right-footed by the unmarked Chair, who coolly passed the ball into the net from 12 yards. QPR remain in the relegation zone, but sit just a point behind fourth-bottom Millwall, whose winless run extended to eight matches with a 2-0 home defeat by Sheffield Wednesday. The Owls had only scored seven away goals all season, but were in front at the break after Anthony Musaba set up Ike Ugbo before finding the back of the net himself. Millwall improved in the second half but failed to carve out many chances on their way to their fourth consecutive defeat.
