Roland-Jones hat-trick floors Derbyshire
A Toby Roland-Jones hat-trick coupled with a five-wicket haul from Tim Murtagh skittled Derbyshire for 60 and helped sweep Middlesex to a nine-wicket win with over a day to spare at Lord's.
Needing 77 for their second victory in as many games, Middlesex lost Sam Robson for a first-ball duck, bowled by Tony Palladino, but raced to victory courtesy of an unbroken second-wicket stand worth 76 between skipper Chris Rogers and Joe Denly who made 28 and 44 respectively.
Derbyshire, having fought hard to secure a slender first-innings lead of 16, crumbled haplessly on day three as they succumbed inside 35 overs for their lowest total against Middlesex.
West Indian Shivnarine Chanderpaul, the number-two batsman in the Test rankings, top-scored with 18 not out but he ran out of partners as wily swing bowler Murtagh started Derbyshire's rout.
A brace of in-duckers trapped Billy Godleman and Wes Durston lbw before Steven Finn responded to being deposited into the Grandstand by visiting captain Wayne Madsen in having him caught behind off the next delivery.
As the ball continued to swing under overcast skies, Murtagh made more inroads after lunch by sending back Dan Redfern and Chesney Hughes with successive deliveries.
Redfern pushed outside the line of an inswinger to become the fifth lbw victim of the day then, to the next ball, Hughes missed out on another off-cutter that pegged back off stump via his pads.
In his next over Murtagh swung one away in the air late, enticing Jonathan Clare to follow with a leaden-footed drive that he edged chest-high to Ollie Rayner at second slip to make it 26 for six and give Murtagh figures of 5-12.
Finn returned to break the resolve of Tom Poynton, one of only three batsmen to reach double figures, before Roland-Jones came on at the Nursery End to wrap up the tail with his hat-trick.
Palladino was caught behind, Tim Groenewald feathered to first slip then Mark Turner's off pole cartwheeled to end the innings and send the players in for an early tea.
The day had started with a rush of seven scalps in the first session as Derbyshire mopped up the four remaining Middlesex first-innings wickets inside an hour, only to then lose three before lunch themselves.
Middlesex lost Rayner leg before for 26 to Turner to bring an end to a seventh-wicket stand with Gareth Berg that added 61 inside 26 overs.
Turner plucked out the leg stump of Roland-Jones via an inside edge, then Clare had Murtagh caught at midwicket and snared Finn leg before with his next ball to finish with 4-40.
