Teenage seamer Sebastian Morgan delivered a career-best four for 48 as Middlesex crushed Gloucestershire by an innings at Lord’s to launch their red-ball campaign with victory for the first time since 2018.

England Under-19 international Morgan, just 18, broke through Gloucestershire’s resistance with two wickets in as many balls before Ryan Higgins’ ruthless spell of three for 18 helped to seal a resounding win.

The Seaxes dismissed their visitors for 215 second time around to emulate the innings success against Gloucestershire at the same venue that closed their Rothesay County Championship season in 2025.

Middlesex are back at Lord’s for the second round of Division Two games on Friday, when they face Worcestershire, while Gloucestershire take on Durham at Bristol.

Needing another 109 at the start of play to make their hosts bat again, it was immediately evident that survival was Gloucestershire’s priority, with Ollie Price and Miles Hammond both curbing their attacking instincts.

Toby Roland-Jones opened with a string of maidens and the morning’s first 10 overs yielded only four scoring strokes, yet the Gloucestershire pair rarely looked under pressure until the introduction of Morgan.

The teenager induced Hammond to play and miss a couple before tempting him to slash a widish delivery through to Joe Cracknell and, when James Bracey was given out leg before to his first ball, the hat-trick opportunity was on.

Graeme van Buuren denied Morgan that prize and went on to cut him for the first boundary of the day, gliding another off Naavya Sharma that nudged the Gloucestershire total beyond 150.

However, Middlesex struck again either side of lunch with the new ball as Higgins flattened Van Buuren’s off stump, then trapped Craig Miles in front for a duck in the first over after the interval.

Higgins made it three wickets in 18 deliveries by removing Gloucestershire’s last recognised batter, with Price castled six short of his half-century, but Matt Taylor and Will Williams held their opponents up with a dogged ninth-wicket stand of 30 that lasted over an hour.

Williams blunted Zafar Gohar, punching him off the back foot for four as the pair edged their side above the 200 mark before a change of spin personnel, in the shape of Josh de Caires, brought about his downfall.

It looked as though Taylor’s battling unbeaten 23 might at least stave off an innings defeat but Gohar, switching to the Pavilion End, pierced last man Gabe Bell’s defences to apply the finishing touch.
