The first team match saw the two unbeaten teams in the division go head to head.
Redbourn, winning the toss and batting first, got off to a flyer, reaching 29 within 3 overs before Gareth Jones found the edge of opener Hales, and Evetts did the rest with a smart low catch to his right.
This brought Conor Yorath to the wicket and from the off, the number three looked composed and calm. He eased his way to 50 but wickets continued to fall around him.
The game could have been so different had ex Knebworth player Alex Salter not survived after a huge edge off the bowling Richmond when he was only on 13. Salter (53) and Yorath then cruised through toward the end of the innings with Yorath eventually falling for and excellent 138 and Redbourn being bowled out for 301. Matt Hutchinson, who has made a welcome return to the cricket field after some time out was the pick of the Knebworth bowlers, finishing with figures of 4-41.
Knebworth never really got going in their reply and fell behind the run rate. The form of Archie Stephens continued as he worked his way to a well-played 44 before falling shortly after drinks. Alex Richmond (30) and some great hitting at the end by Neil Hart (35) saw Knebworth reach 210 all out, gaining 17 points from the day and enough to keep them on top of the table.
