Andrew Strauss defended England's batsmen after the hosts lost four wickets in the final session on day one of the second Test against Australia.
Strauss was unbeaten on 161 but a late flurry of wickets left England on 364-6 and reinvigorated Australia's resolve.
But the England captain said: "The guys generally got pretty good balls.
"From 196-0 to six down is a little disappointing, but if you can get to 450-odd tomorrow then you are always in a good position in the game."
Strauss shared a superb first-wicket stand with Alastair Cook, surpassing England's previous opening partnership best against Australia at Lord's, set 83 years previously by Jack Hobbs and Herbert Sutcliffe.
Cook fell five runs short of a deserved century but Strauss continued to cut, pull and drive his way to his 18th Test century, finishing 16 runs short of his best score for England.
"You always get value for your shots at Lord's," Strauss told BBC Radio 5 Live. "I feel in good rhythm in my batting.
"When you are in good rhythm, you don't put yourself under too much pressure.
We were looking down the barrel of a very long day, so it could have been a lot worse

"If we can get 450 we're in the game - if you can get to 500, you control the game.
"We lost four wickets in that final session, it put a little more responsibility on my shoulders to be there at the end. Thankfully I was able to do that.
"I'll try to have a good night's sleep and hopefully get some more runs tomorrow."
After an indifferent first-session display, Australia's bowlers began to swing the older ball in the final session in overcast, humid conditions.
However, Strauss believes the movement will encourage England's seam quartet just as much as Australia's quicks.
"There was certainly more in this wicket than there was in Cardiff, when the ball started swinging it made batting quite difficult," he said.
"But there are wicket-taking balls out there, in between scoring opportunities. It's a good cricket wicket.
"Hopefully we can get the ball swinging. That's going to be crucial for us - hopefully we can get some good overhead conditions and shape the ball around."
