Middlesex and Glamorgan have not met in one-day cricket since 2007. That match was played at the picturesque Eugene Cross Park in Ebbw Vale, which was the last time it was used by Glamorgan in a first XI game.
You have to go back to the last Century to find the last Glamorgan one-day win at Lord's against the Panthers - April 1999 to be exact when the Welshmen won by 35 runs.
Matthew Maynard's 151 not out for Glamorgan against Middlesex in 1996 remains the highest score by a visiting batsman in domestic one-day cricket at the game 'Headquarters'.
Glamorgan were unable to win any of their last four matches in the 2012 CB40 (lost 3, no-result 1), while Middlesex didn't lose in their last four (won three, tied one v Worcestershire).
