Jonny Bairstow and Joe Root celebrated their call-up to England's Test squad by sharing an unbroken stand of 81 for the Lions on the third day against New Zealand.
Rain wiped out two sessions of play at Grace Road, but the Yorkshire duo took their chance to overtake the visitors' target of 285 all out in the 22 permitted overs for the day.
Bairstow (45no) and skipper Root (143no) took the young Lions onto 315-4 - a lead of 30 runs in a match which is highly likely to end in a draw at some point on Sunday.
Nightwatchman Chris Wright (5) lasted four overs, edging Trent Boult to slip when the left-armer found just enough movement slanted across him.
Then James Taylor mustered two runs on what was once his home ground before falling to a shot he would doubtless prefer to forget quickly, sparring on the back foot and edging behind off Boult.
Bairstow, who can once more expect to bat at number six at Lord's next week, came in to make some quick-fire runs.
Afterwards, the 23-year-old from Bradford stressed that recent runs are much more significant than the knowledge he fared so well on his last Test visit to Lord's when he impressed with scores of 95 and 54 against South Africa last summer.
"I've obviously got very fond memories of that game. But that's a very long time ago now," he said.
"It was a very good Test match for me. I was very pleased with the way I did.
"But you don't tend to look back six months to that; you tend to recall much more recent innings and performances to build confidence."
Meanwhile, New Zealand seamer Tim Southee will take no part on the final day of the tour match, after hurting his left foot in the course of bowling five overs this morning.
He is due to see a specialist, but is not yet considered a doubt for the Lord's Test.
