Abigail Wallace became the first Horspath player to hit a century in the Home Counties Women's Cricket League with a brilliant 109 in a monumental 115-run win over Haddenham at the Recreation Ground.
The opener's runs came off just 78 balls and included 18 fours as Horspath posted their highest score of 297-3 after electing to bat in the Division 3C encounter.
She shared a stunning 184-run first-wicket stand with Tracey Isaac, who made a fine 73 from 56 deliveries with 11 fours.
Abigail continued the run spree in a second-wicket partnership of 89 with Victoria Montgomery (38), completing her century before her wonderful innings ended when she was bowled by Olivia Shaw.
Horspath's total, which included 74 extras, comfortably surpassed their previous best score of 200-2 in their opening day win against Chesham 2nd in June.
With the match played in an excellent atmosphere as both home and away supporters watched the action throughout the day, Abigail (3-34) and Victoria (3-35) shone with the ball as Haddenham were then held to 182-6.
Irum Ibrahim opened up with an accurate spell of five overs for 24 runs, before wickets fell after Victoria Shaw (51) and Edie Hayes (49) shone for the Bucks club.
However, Haddenham never threatened Horspath's huge score, although it didn't produce a record margin of victory, which remains the 134-run triumph against Chesham.
Horspath will be looking to repeat the feat when they travel to Haddenham for the reverse fixture on Sunday.
The victory saw Horspath bounce back to winning ways following a six-wicket defeat at Dinton in their previous outing despite posting a challenging 177-5.
Tracey (56 ret no) and Abigail (25) gave the visitors a good start with 58 for the first wicket after they chose to bat. Victoria (42) then joined Tracey to put on 103 for the second wicket.
However, it didn't prove enough as Freya McCrea (102no) steered Dinton to 178-4 as Abigail took two wickets and captain Munaza Dogar and Tracey picked up one apiece.
It was a much improved performance by the visitors after they had gone down by nine wickets in the home fixture against the Bucks club two weeks earlier.
Horspath were bowled out for 83 after being put in to bat with Kathryn Goodliffe (19) top-scoring, before Dinton replied with 84-1.
High Wycombe also proved formidable opponents back in June, rattling up 248-3 after electing to bat on their home ground to set up a 178-run win.
Munaza claimed 2-37 and Anushka Satish also picked up a wicket as Sophia Sketchley (103no) and Sue Benson (82) piled up the runs.
Munaza (13) top-scored for Horspath but the side were 70 all out with Ruby Juster-White (4-11) and Anna Cooper (3-13) leading the way for Wycombe.
Horspath's fixtures also took them to Chalfont St Peter, who came out on top by six wickets.
Frances Goodliffe (14) was the main contributor as the visitors were bowled out for 85 after choosing to bat, before taking 2-13 in the hosts' 89-4.
Meanwhile, Horspath Hurricanes have been in action in the Oxfordshire Women's Hundred where Harshi Wijernerathna has been the side's star performer.
She smashed 85 not out in a 74-run loss at home to Oxford after making an unbeaten 66 in a four-wicket defeat by Moreton at the Rec where Victoria chipped in with 28 not out.
Horspath are back in Hundred action at home to Steventon on Friday (August 14).
