MERSTHAM have marked their 150th anniversary year with promotion and will now battle with Chaldon for the Division Two title.
Merstham chose to bowl and dismissed their hosts Wandgas for 153 in the 39th over, before overhauling the total with seven wickets down.
They made quick inroads, with Nav Javid taking two quick wickets to reduce the hosts to 2-1 and 4-2 but they had to wait a while before taking a third, making the score 40-3.
That was because Phil McDonnell took the scoring strike, making 84 before becoming the seventh wicket, eventually snared by Ammar Tahir lbw.
McDonnell had taken the initiative with most partners, Tharusha Tilakarathne being the only other player to reach double figures before going for 17, caught by Jonathan Deans off Asim Jafferi, who now has 24 wickets this season.
Two late run-outs also helped Merstham's cause after Humayoon Nasir bowled three middle order batsmen in an economical spell of 3-29, despite no maidens, also taking his wickets tally to 24.
Javid's damage, including a caught and bowled, gave him figures of 3-37 while Tahir took 1-14 and has a top-scoring 34 wickets for the side this summer.
In reply, Merstham did not have things all their own way, losing seven wickets as they negotiated victory in 40 overs.
Asher Syed took his runs for the season past 300 with an opening 29, forming an opening partnership of 39 with Jason Kyte (31) before being caught.
Another 30 was added between Syed and Andy Rivers before the latter was caught and bowled for 17 by Alex Marsh.
After Kyte's dismissal, Noman Kiyani also added the same score, 31, but the next three batsmen were out cheaply.
Captain Naveed Saeed (13no) came to the crease and, with Wasil Mohar (11no) steered Merstham over the line.
