Mark Noble's penalty 14 minutes from time gave West Ham a narrow 1-0 win over Hull City at London Stadium on Saturday.
Three days after his winner against Burnley, it was captain Noble who gave West Ham the three points again, rolling a penalty home after Tom Huddlestone brought down Michail Antonio.
Dieumerci Mbokani hit the post for Hull in the first half after capitalising on Aaron Cresswell's mistake, before Noble nearly diverted into his own net after half-time, hitting the bottom of the woodwork with a header.
The result leaves West Ham 13th following their first back-to-back Premier League wins at London Stadium, while Hull are now bottom, having won just once in 14 league games.
Andy Carroll started consecutive league games for the first time this season, while Mbokani came in for Adama Diomande for Hull.
Michael Dawson did well to block Dimitri Payet's effort from inside the area early on, but Hull had most of the chances in the first half in east London.
Mbokani struck inches wide from 20 yards, before the Congolese striker missed the best chance of the opening 45 minutes, hitting the inside of the post after latching onto Cresswell's poor backpass to go through on goal.
Darren Randolph then beat away Harry Maguire's header from a Robert Snodgrass corner, while Pedro Obiang nearly diverted the ball into his own net as he snuffed out Maguire in the area before the break.
Hull continued to create the chances after half-time, as Noble headed onto his own post past Randolph from Andrew Robertson's cross, before Robertson himself hit the post from inside the area with a fierce left-footed effort that looked destined for goal.
Robertson then cleared off the line from Andre Ayew's header from Payet's corner, while David Marshall saved well from Antonio's left-footed shot from an angle.
Edimilson Fernandes cleared off the line at the other end from Maguire's header, before the breakthrough came in the 76th minute.
After the ball bounced around the Hull area, Huddlestone dragged down Antonio, deemed by Lee Mason to be a foul, leaving Noble to slot the ball home for the winner.
Maguire could have equalised for Hull late on, but Randolph kept out the defender's effort from an angle when squaring for team-mates looked the better option.
