West Ham manager David Moyes tried to defend Joe Hart but the goalkeeper's hopes of going to the World Cup with England are once again in danger of slipping through his fingers.
Hart, who lost his West Ham place earlier this season, gifted Stoke a goal on Monday night when he fumbled a straightforward shot from Xherdan Shaqiri, allowing Peter Crouch to stab the ball home.
It was not an isolated incident, either, with Hart making a similar mistake against Burnley last month, although that error was somewhat overlooked amid supporter protests and pitch invasions.
This time, however, England manager Gareth Southgate was in attendance, running the rule over Hart and opposite number Jack Butland.
"He had two similar shots in the first half and took them comfortably, so it was a surprise that it spilled out," Moyes said. "But if you are a goalkeeper it's going to happen. Just like last week when he made some fantastic saves at Chelsea I didn't go over the top.
"I just told him 'well done' and now I'll just tell him he should have done better with that one."
At least the blunder did not cost West Ham as Andy Carroll emerged from his latest spell in cold storage to hit a last-minute equaliser and snatch a 1-1 draw.
The injury-hit striker has been out since the turn of the year following ankle surgery but took just four minutes to secure a point which edged the Hammers closer to survival.
Stoke remain in trouble, five points from safety with just four games to play, and left manager Paul Lambert cursing his luck even though West Ham had three goals disallowed including a late 'winner' for Javier Hernandez.
"I must have walked under a ladder or broken a mirror," said Lambert.
"I thought we deserved something from the game, we played a really good game and if we keep playing like that we will win games.
"If there is a little bit of lady luck it hasn't come our way but the performances have been very good."
