Hull City kept alive their bid to avoid relegation after coming from behind to beat Middlesbrough 4-2 in the Premier League on Wednesday and pile more pressure on their beleaguered rivals.
However, it was extended to 40 in a pulsating contest at the KCOM Stadium, Lazar Markovic's first Hull goal and an Oumar Niasse strike turning the game on its head.
The Tigers have now taken 16 points from a possible 18 in their last six home league games to give their survival battle real momentum and Silva said his side's display was their best since he took charge in January. In the second half, we controlled the game.
Maguire's diagonal ball was crossed first time by Grosicki from the right and with Valdes stranded, Hernandez steered home his fourth league goal of the season.
Middlesbrough - winless in 13 matches - are second from bottom and seven points adrift of Hull.
Hull thought they had drawn first blood, but Niasse was deemed offside when he turned the ball home at the end of a slick move in the third minute and the first blow was landed by Boro two minutes later.
Hull now sit on 30 points having played 31 matches and captain Dawson is confident they can go on to retain their top-flight status.
The visitors did get one back in controversial circumstances in time added-on at the end of the first-half.
Andy Robertson's deflected cross in from the left caused confusion in the Middlesbrough defence and after Hernandez had seen his effort from close range blocked, Markovic followed up to poke the ball into the net.
There was initial confusion over whether the goal had been given as referee Michael Oliver went to consult with the linesman.
Hull gave themselves some much-needed breathing space and restored their two-goal cushion in the 70th minute when Maguire stole in unmarked at the far post to head home Robertson's curling cross. Middlesbrough: Victor Valdes 6, Antonio Barragan 5, Daniel Ayala 6, Ben Gibson 6, James Husband 5, Adama Traore 7, Adam Clayton 6, Marten de Roon 7, Stewart Downing 6, Alvaro Negredo 7, Rudy Gestede 6.
Boro, who have taken one point from three games since sacking Aitor Karanka last month, were backed by 2,500 travelling fans at the KCOM, where Agnew spent over two years as assistant boss to Steve Bruce.
