Royal London One-Day Cup table-toppers Essex and Worcestershire discovered their prospective semi-final opponents early after rain washed out three matches in the last round of South Group fixtures.
Essex already learned, with their group match the only one to survive a Wednesday afternoon deluge and therefore still going on into the evening against Kent at Canterbury, that they will host the winners of next month's quarter-final eliminator between Somerset and Nottinghamshire at Taunton.
Worcestershire's opponents at New Road will be either Yorkshire, runners-up behind them in the North Group, or 2015 and 2016 finalists Surrey - who will meet in their eliminator match at Headingley.
The Lord's final will take place on Saturday July 1.
Eliminator quarter-finals (to be played on June 13): Somerset v Nottinghamshire and Yorkshire v Surrey
Semi-finals (to be played June 16/17): Essex v Somerset/Nottinghamshire and Worcestershire v Yorkshire/Surrey
