Glamorgan captain Sam Northeast hit the highest first-class score recorded at Lord's as he made an unbeaten 335 against Middlesex on day two of the new County Championship season.

Northeast, 34, overtook Graham Gooch's 333 for England against India in 1990. The Englishman put on an unbeaten stand of 299 with Colin Ingram (132 not out) in Glamorgan's total of 620-3 declared.

Northeast's innings is also the highest Championship score ever recorded in April. Having come to the crease on Friday morning with Glamorgan's score at 16-1, Northeast faced 412 balls, hitting 36 fours and six sixes.

He put on 129 with Billy Root (67) for the second wicket and 176 with Kiran Carlson (77) for the third wicket. Middlesex replied strongly when they got the chance to bat, reaching 138-1 with Mark Stoneman on 62.

Northeast now has the two highest individual scores for Glamorgan after hitting 410 in 2022, with David Lloyd and Steve James also having treble centuries to their credit. Glamorgan accumulated relentlessly in the Saturday morning session as Northeast passed the county's previous best individual score against Middlesex, 226 by newly appointed chief executive Dan Cherry.

There were few fireworks in the first 90 minutes as Northeast and Ingram settled for four batting points. But Northeast stepped up the tempo with three legside sixes off Ryan Higgins before lunch as Middlesex went on the defensive.

Northeast was mostly impeccable but offered a gully catch and a stumping chance late in his innings, before setting his sights on the ground record. The closing stage of Glamorgan's highest team score against Middlesex was a one-sided affair as Ingram opened his shoulders to blitz into three figures after a mostly restrained knock by his standards, hitting 12 fours and four maximums.

With 471 needed to avoid the follow-on - and in turn condemn the match to an almost certain draw - Stoneman and Sam Robson showed little sign of scoreboard pressure getting to them. Glamorgan's bowlers, featuring newcomer Mir Hamza and loanee Craig Miles, toiled as the openers added 79 before Miles produced a peach of a delivery to bowl Robson through the gate for 43.

Left-handers Stoneman and Max Holden, both short of runs in division one in 2023, had few alarms in the closing stages as bat continued to dominate ball.
