Glamorgan’s former Kent, Hampshire, Yorkshire and Notts man Northeast made the highest score ever seen at Lord’s when he surpassed Graham Gooch’s ground record 333 to pile up 335 in the Championship back in April.
This time he made a mere 67 in 45 balls, including a crucial missed stumping – but it was more than good enough.
Middlesex got off to a great start with a 108-run opening stand between Martin Andersson, who hit 57 off 34 balls – his first T20 half-century – and Stephen Eskinazi (48).
But Middlesex then lost all 10 wickets for just 65 runs. Mason Crane (3-28) began the slide before a Timm Van der Gugten’s triple-wicket maiden, including the scalps of Luke Hollman, Tom Helm and Henry Brookes, sent Middlesex collapsing to 173 all out.
The visitors always looked comfortable in pursuit after Kiran Carlson’s five sixes in a opening salvo of 54 off only 21 balls.
Despite three wickets for Middlesex’s winter signing from Warwickshire Henry Brookes, Northeast’s miss proved costly as was dropping Chris Cooke (21) as the visitors chased down their target to reach 177-7 with 10 balls to spare.
