New-ball bowler Jack Brooks has left his former county Northamptonshire on the ropes with a five-wicket burst during a remarkable second afternoon of the LV= County Championship match at Headingley.
Brooks struck five times in his second spell to leave Northants at 65-7 in reply to 459-9 declared.
Ryan Sidebottom claimed four wickets and Liam Plunkett one as Northants were bowled out for 98 just before tea to cap an incredible afternoon which saw ten wickets fall.
Brooks bowled former Pudsey Congs and Bowling Old Lane all-rounder James Middlebrook before getting Rob Newton caught behind, Andrew Hall caught at third slip by Kane Williamson, David Willey caught in the gully by Plunkett and and Steven Crook caught at point by Adil Rashid.
The wickets of Newton and Hall came in the 17th over.
Sidebottom trapped Stephen Peters lbw and had Kyle Coetzer caught at second slip, leaving Northants at 27-3 in the 11th over.
When Plunkett later had David Murphy caught behind in the 24th over, Northants were 68-8.
Sidebottom wrapped up the innings by bowling Maurice Chambers and getting Azharullah caught at first slip to leave him on a hat-trick at the start of the Northants second innings. Brooks finished with 5-36 and Sidebottom 4-16.
