Mark makes impressive debut but Saints are sunk by Church Gresley
Adam Warrington (Blackstones) is three wins away from the final of the Northants Federation two-bowl singles - a title he has won multiple times and on three occasions has gone on to lift the national championship at Skegness.
After beating Crowland's Peter Holmes, he faces an intriguing third round tussle at home to Market Deeping-based Sean Fenlon, representing the West Ward club in Peterborough.
Also through is John Holroyd, who outbowled Howard Shipp 21-4 in wet and miserable conditions and will meet Mick Humphreys (Blackstones) who scored a similar win over Jeff Clipston at the Peterborough & District green.
A victim of the enigmatic Whittlesey Town green was last year's county two-bowl s singles runner-up Dave Roberts (Market Deeping) who was beaten 21-8 by Ralph Barker.
Humphreys was beaten 21-14 by club mate Stephen Harris in the four-bowl singles while Stamford Town's Richard Allam beat Cliff Watson (P&D) and will play Lee Welsford (Whittlesey Manor) for a place in the quarter-finals.
In the champion of champions singles Vanguard's Malcolm Mann beat Harris 21-17 and faces Parkway's former English triples champion James Harford, while Peter Cox (Langtoft) - a 21-20 winner over Tony Mace (Whittlesey Manor) - will play Cliff Watson.
Wittering duo Dave Burton and Ally McNaughton have reached the quarter-finals of the pairs, defeating Ketton's Dick Ford and Bob Warters 19-13.
In the two bowls triples the rinks of Mick Humphreys and Richard Allam will play each other for a place in the semi-finals after defeating the respective Blackstones triples of Paul Bailey and Tom Fielding.
Ketton's Ken White, Phil Hoare and Charlie Underwood put up stubborn resistance in the three bowl triples before losing 11-13 to Stuart Reynolds' Parkway trio.
In the women's pairs there was mixed fortunes for Ketton. Elizabeth Wallace and Carol Warters beat Doris Flowers and Joan Padley (Yaxley) 22-10 and in the quarter- final will face Kath Browning and Viv Hempsall, who beat Shirley Suffling and Chris Ford (Ketton) 19-10.
Ahead of Northants Women's Federation's series of county matches in the Donald Steward Trophy and Silver Jubilee Vase, Ketton's Christine Ford staged her President's Day at her home club at which more than 30 bowlers attended.
As part of their 45th anniversary celebrations, Ketton Bowls Club will host matches in the Donald Steward competition against North Essex (June 12, 1pm), Norfolk (June 19) and North Cambs (June 26). The team will be away to Suffolk and Hunts on July 3 and 10 respectively.

Mark Hebden underlined his debut for the Stamford Saints in the English Indoor Bowls Fantastic Fives League with an impressive 11-8 singles win over Church Gresley's Mark O'Connell.
He trailed 5-8 but picked up six shots in the last three ends of this 12-end contest to give his team a flying start.
Sadly however, though Jeannette Bourne, David Howarth, Chris Barnes and Roger Graham drew the fours 8-8 - after trailing by two with an end to play - the match ended in a 9-15 defeat for the pairs (Barnes and Hebden) and the triples (5-18).
Stamford Bulls were due to play Charnwood on Wednesday.
