Dawid Malan made an unbeaten 154 as Middlesex put themselves in a position of dominance on day two of their LV= County Championship fixture against Northamptonshire at Lord's.
Malan's score, his highest of the summer so far, helped the hosts to 488/9 declared, and they had chipped away at the Northants top order by the close to leave them 89/3 when rain and bad light caused a premature end to proceedings.
James Kettleborough batted well for the visitors to reach 42 not out, but a wicket each for seamers Tim Murtagh, Steven Finn and Toby Roland-Jones put the Panthers in command.
Malan earlier batted throughout the remainder of the Middlesex innings after resuming on 72 not out.
Neil Dexter, his overnight partner, and Joe Denly came and went without making a big impression - making 20 and 17 respectively - but Malan found a partner in John Simpson.
The wicket-keeper batsman helped him put on 128 for the sixth wicket, a partnership which took the game completely into the hosts' hands before captain Chris Rogers called it a day with the fall of the ninth wicket.
