They trail the hosts by 61 runs going into day 4 of their County Championship Division Two fixture.
Dawid Malan and Billy Godleman joined something of an exclusive club as the game between Middlesex and Derbyshire meandered towards a draw on day three at Lord’s.
The respective captains became just the fifth and sixth batsmen in Division Two to reach Championship runs for the season on the campaign’s penultimate day. Only Warwickshire’s Dominic Sibley has managed the feat in Division One.
Malan’s came in a score 72 out of a Middlesex total of 260, while Godleman achieved four figures when reaching 19, going on to make 27 as Derbyshire replied with 199-4.
The loss of much of the first two days to rain means without contrivance this game will peter out on the final day of the season tomorrow.
Middlesex began a day which started 45 minutes late on 199-5 and Malan, left on 999 for the season overnight, raised his landmark by stroking his first ball to the cover boundary, but departed soon afterwards LBW to Luis Reece (4-54).
The left-hander was given a loud ovation by the members as he left the field and he responded by raising his bat to all sides of the ground perhaps fuelling speculation this week that this was his farewell game for the tenants of Lord’s.
Reece claimed a fourth wicket when Toby Roland-Jones was LBW playing no shot before Fynn Hudson-Prentice (3-65) mopped up the tail, leaving James Harris 25 not out.
Godleman and Reece started with a flurry of boundaries, the openers added 49 in less than 10 overs before Bamber removed the latter LBW for 26 with the score on 49.
When Wayne Madsen went the same way first ball Bamber was on a hat-trick, but excitement got the better of him as a leg-stump delivery on the hip was tucked away for two runs by new batsman Leus Du Plooy.
Nevertheless, Derbyshire were 55-3, having lost three wickets for six runs, when Godleman edged Roland-Jones to Malan at slip.
Du Plooy and Alex Hughes steadied matters with a stand of 48, but Murtagh returned to have the latter caught by Miguel Cummins at wide mid-off just prior to tea.
The third session saw Derbyshire in charge, Du Plooy finding an ally in wicketkeeper Harvey Hosein, the pair prospering against Middlesex’s seamers who persistently banged the ball in too short.
Hosein was first to reach 50 from 80 balls with six fours, while Du Plooy took 31 deliveries more, but with eight boundaries.
Bad light ended play shortly afterwards leaving meaning another 16 overs were lost in this weather ruined fixture.
