"I don't know why people say we're lucky with the refereeing decision," Jones said, "The TMO has all the time in the world to make his decision."
Both teams relied on kicking games in constant drizzle and England were better at it against a Wales side rocked before the match by the withdrawal of fullback Leigh Halfpenny. That saw a first championship start for former Blues and Chiefs back Anscombe, who played well.
Halfpenny starred in the opening rout of Scotland, but a foot infection sidelined him, and without his nous, Wales were immediately exposed under the high ball. Anthony Watson outjumped Rhys Patchell, allowing Owen Farrell to arrow a low kick behind the Welsh defence for May to touch down in the third minute.

Halfpenny's goalkicking was also missed, as first-five Patchell missed an early penalty opportunity before turning down a couple of others that Halfpenny would have considered regulation. Where Wales struggled, England's Mike Brown excelled. He effortlessly plucked kick after kick out of the air to stymie Wales and launch counter-attacks.
"They [England] were very, very good in the air and dominated that aerial battle and as a result probably dominated a bit more territory and possession," Gatland said. "That was kind of what hurt us a little bit."
The influential Farrell was involved once more as England breached the Welsh in the 20th minute, finding out wide lock Joe Launchbury, who flicked a deft pass inside for May to grab his second try.
Anscombe then appeared to beat England wing Anthony Watson to the ball in-goal but TMO Glenn Newman advised referee Jerome Garces not to award the try. The disbelieving visitors were forced to settle for a Patchell penalty.
"I thought Gareth got there," said Gatland. "His hand was there and clearly there's downward pressure. It's human error, he makes a mistake, but at this level in front of 82,000 people when there's a lot at stake, guys have got to get those decisions right."
Anscombe moved to his preferred No 10 position and Josh Adams shifted from wing to fullback. The adjustment almost paid immediate dividends, only for Underhill, on in place of injured No 8 Sam Simmonds at halftime, to prevent a certain try by taking out Scott Williams' legs.
But Wales came again, North carried his side up the field with a storming run, leading to a penalty in front of the posts. Trailing by nine with just three minutes remaining, Anscombe converted the penalty to bring Wales within a converted try of victory.
The tension heightened around Twickenham but England produced a clinical defensive set from the kickoff to keep Wales inside their own half and close out a crucial victory.
