ELWORTH professional Ian Mitchell hit a century to help his side claim a Premier League scalp in the first round of the Sentinel Talbot Cup on Sunday.
High-flying Porthill Park were sent crashing out of the competition as First Division Elworth produced an all-round performance to upset the odds.
South African Mitchell bludgeoned 15 fours and a six in his magnificent 106 to pave the victory foundations.
The all-rounder took to the hard, dry batting track as he added 94 runs for the second wicket with opener Mike Robinson (29). Skipper Dave Palin (39) then helped pile on the agony for Porthill as Elworth amassed 223-6.
Park started well in reply but when Staffordshire batsman Jamie Jervis was bowled by a Paul Crompton inswinger, Elworth sensed their chance.
Spinner Jim Higgins exploded into action, picking up the vital wicket of Park's South African professional Pierre Joubert with his second ball.
Higgins went on to take 4-27 from his stint, but Cotton (42) and Elsmore (19) helped Park to 96-5 after 26 overs.
Mitchell then removed Cotton in his second over before going on to claim 3-34 from seven overs, as Park sacrificed wickets to maintain their challenge.
It was a gamble which didn't pay off as Park were bowled for 174 in the 40th over to help Elworth earn a shock second-round date at Moddershall.
Betley cruised into round two with an eight-wicket defeat of Barlaston.
After restricting their visitors to 200-8, Simon Cork smashed 85 and Darren Brierley an unbeaten 72 to guide Betley home at 201-2.
Former Derbyshire and England star Kim Bennett almost single-handedly put Crewe out of the competition.
Now playing for Premier League Checkley, Barnett took 4-26 off nine tight overs and followed up with a superb 81 not out to guide the visitors to an eight-wicket victory.
Crewe's total of 145-8 was built around Aamir Iqbal's patient 52, with support from Mark Hurst (25), Tom Gower (17) and Matt Dawson (15).
The only Crewe bowler to taste success was Dawson with 2-29 as Checkley eased home with four overs to spare.
Aston suffered a shock setback as they fell to a nine-wicket defeat against Trinity at Bramhall in the Cheshire Building Society Alliance Cup.
Aston went for 125 with Ron Bedson (62) and Andy Leese (33) their only players to score more than a single. Trinity cruised to victory at 127-1.
Weston were also sent tumbling out of the J Whitfield Senior Knockout Cup at Oakamoor.
Home pro Sohail Rauf did the damage, taking 3-20 in Weston's innings of 78-9 before hitting an unbeaten 44 in Oakamoor's reply of 81-2. Readers Talbot Shield scores - Round one: Barlaston 138-2, Crewe 134-8; Checkley 81-2, Betley 79ao; Rode Park 160ao, Haslington 96-8; Stone 190-7, Elworth 193-4.
