Roland-Jones routs Northants
Toby Roland-Jones finished with 12 wickets as Middlesex blew away Northamptonshire by an innings and 84 runs to go top of Division One.
Roland-Jones' career-best match figures of 12 for 105 helped his side complete a convincing victory as the hosts were bowled out for 176 in 87.5 overs at Wantage Road.
The 26-year-old's return of six for 50 also equals his best figures for a single innings.
The win is Middlesex's fourth from their six matches so far and means they move 19 points clear of second-placed Yorkshire, who have a game in hand.
Entering the final day on 88 for four, Northants needed another 172 just to make their opponents bat again and avoid a fourth defeat in five games, with early wickets all but ending any hopes of a comeback.
Rob Newton (18), Andrew Hall (six) and David Murphy (nought) were all dismissed in the first nine overs of the day and having added just 19 runs to the scoreboard.
Newton and Hall were both caught behind off the bowling of Tim Murtagh (two for 40) and Roland-Jones respectively, and two overs later, Roland-Jones had Murphy too as he clean bowled the wicketkeeper-batsman to leave the score 103 for seven.
It was then only a matter of time before Middlesex wrapped up the victory but they were made to work for their win as Ben Duckett (56 off 136 balls) and Ian Butler (14 of a staggering 119 deliveries) occupied the crease and made sure play went beyond lunch.
The pair dug their heels in, scoring just 23 runs in 27.4 overs before the interval but the resistance was finally broken when Butler was caught behind off Roland-Jones in the 84th over.
The final two wickets then came easily as Duckett's vigil ended soon after by Roland-Jones before the result was confirmed when Dawid Malan ran out Mohammad Azharullah.
