Much-vaunted all-rounder Steve Whitwam put in a typically strong performance for the visitors, making 111 out of his side’s 209 for five and following up with two for 69 off 21.2 Overs.
However, Niall Lockley (69), skipper Paul Winrow (54) and Lorenzo Ingram (53 no) scored freely off Golcar’s other bowlers to win with 10 deliveries to spare.
Earlier, spinners Chris Goulden (three for 78) and Ingram (two for 73) had got through 35 overs between them to keep the visitors in reasonable check, although an injury to young bowler Jack Hendy was a worry for Elland.
Elland followed up in the Sykes Cup on Sunday with a 10-wicket flattening of minnows Emley Clarance.
Stuart Thompson enabled Illingworth to grab an unlikely victory at Horsforth and leapfrog their hosts into fifth position in the Aire/Wharfe League.
The visitors, chasing 196 to win, looked dead and buried at 114 for seven with 82 runs still needed off the last 20 overs.
However, Thompson and Alex Ledger added 49 before Ledger departed for 37 with 32 still to get. Thompson shunned thoughts of shutting up shop and settling for a draw. With Liam Kelly at the other end he made an unbeaten 47 off only 50 balls to clinch a two-wicket win.
Earlier, an Illingworth side without Jamie Moorhouse and Veryan Brooksby were unable to prevent Horsforth racing to 48 without loss after 10 overs.
Luke Brooksby eventually made the breakthrough and then ran out home skipper Chris Binks for 52 before Ledger kept the scoring down in the middle overs with one for 27 off 15 overs. The home side add 65 in the last 10 overs but their total proved not quite enough.
Northowram Fields slipped to eighth in the Central Yorkshire League’s top flight with a five-wicket defeat at home to bogey side Hunslet Nelson.
Skipper Tom Marsden (68) and teenager Jacob Waterson (78) were again among the runs after Marsden had elected to bat.
A total of 223 for seven looked reasonable but the Rams’ scoring lacked acceleration and left them vulnerable to the Nelson batsmen.
The visitors’ reply got off to a brisk start and they survived a blip when they lost their third and fourth wickets with the score on 107 to win a shade comfortably, spearheaded by half-centuries from Dan McTernan and Joe Smith.
Northowram made some amends in the Jack Hampshire Cup on Sunday when they beat division-lower Scholes by 11 runs.
They did it with the help of a half century from South African James McCartney, who followed up with two wickets in his first over when the visitors appeared to have the upper hand.
Lightcliffe picked up a useful away win in the top section of the Bradford League, Jonathan Wilson’s side beating Bradford and Bingley by 35 runs.
Chris Taylor (77) and Alex Lees (61) are now well into their strides after a slow start to the season and their second-wicket stand of 107 paved the way for a Lightcliffe total of 222 for five.
The hosts slipped from 65 for one to 106 for six and the loss of three more wickets with the total on 159 virtually sealed their fate, spinner Josh Wheatley’s four for 55 doing the trick for Lightcliffe.
Brighouse have only Idle below them in Division Two of the Bradford League after their bowlers were put to the sword by Baildon’s Gharib Razak.
The opener smashed 108 off 82 balls as Baildon raced to a target of 160 in 25.2 overs.
The visitors had not suspriringly elected to bat in glorious conditions but after making reasonable progress to 76 for two their innings fell away with only Umar Salim (43) and Dom Walsh (32) making significant contributions.
