A superb unbeaten 142 not out helped Nawton Grange to a crucial home win against fellow Readers Beckett Premier Division strugglers Cloughton.
In a high-scoring encounter Lush dominated as Grange posted 239-8 on a day when many other sides in the top flight struggled with the bat.
Tom Garbutt's 27 was the only other home innings of note, Aaron Virr bagging 3-55, Henry Whelan 2-29 and Callum Ferrie 2-35.
Ben Luntley struck 62 and Paul Virr made 58 in reply, but their teammates failed to follow their lead as they were dismissed just 10 runs short of Grange's tally, Josh Greenlay, Garbutt and Nathan Marwood picking up two wickets apiece.

Forge Valley remain second after holding their nerve at Ebberston, Nasar Khan's 6-22 firing the Ayton side to victory.
Tom Varey's 44 proved to be vital as Valley were made to work hard for their 141-7, Ian Atkinson and Tom Holmes taking two wickets each.
Matty Turnbull fell three short of his half-century, but his teammates failed to deal well with bowling of Khan as the hosts slipped to 121 all out.
Fifteen wickets fell with only 163 runs scored at Clarence Drive, where Filey edged past Scalby by five wickets.
Josh Dawson was the main main for Filey, taking 5-33 as Scalby collapsed to 81 all out, Phil Dickens chipping in with 3-14.
The hosts then look in deep trouble until an unbeaten sixth-wicket stand between Dawson (35no) and Aaron Howard (20no) saw Filey home.

Heslerton’s title challenge faltered as they lost out by 35 runs on their own pitch against Seamer.
The hosts made a great start to the match, reducing Seamer to 29-4 within the first 13 overs but a 54-run partnership between Corey Towell (30) and Craig Baker (17) arrested the slide leaving a final forceful 45 from Jamie Griffin to take the final total to 146 after 42 overs, Adam Spaven finishing with 4-37 and Dan Jeminson 3-28, the home team’s cause not being helped by a spate of dropped catches.
Replying Heslerton lost an early wicket but Rob Middlewood (29) and Tom Benthall (23) increased the total to 48.
When both departed only a belligerent innings from Sam Triffitt (18) put any doubts in a rampant Seamer team as the home team gained a relatively easy victory by 35 runs, Adam Morris claiming 4-27 and Griffin 4-22, the last seven wickets falling for only 18 runs.
