Yorkshire leave Notts reeling
Division One leaders Yorkshire forced Nottinghamshire to follow on as 16 wickets fell on the second day of their LV= County Championship clash at Trent Bridge.
The home team reached the close on 118-4 second time around, having earlier been shot out for 150 in reply to Yorkshire's impressive first-innings total of 407.
Steven Patterson made 40 with the bat - his highest score of the season - before then claiming career best bowling figures of 5-43 as Nottinghamshire were left facing a deficit of 257 after both sides had batted once.
The 29-year-old shared in a ninth-wicket stand of 91 with Jonny Bairstow, who was last out for 62 off 70 balls, as Yorkshire secured a fourth batting point in adding 80 their overnight score of 327-8.
Ryan Sidebottom dismissed Alex Hales and Michael Lumb for ducks before lunch and then Patterson struck immediately after the interval, Steven Mullaney edging the seamer through to wicketkeeper Bairstow to leave the score at 25-3.
Former England international Sidebottom removed Samit Patel, aided by a Phil Jaques catch at short midwicket, and had Riki Wessels caught behind to finish with fine figures of 4-35.
David Hussey and Chris Read were both sent on their way to lbw decisions against Patterson, who collected his fourth scalp as Luke Fletcher drove to Adil Rashid.
Having lost six wickets for 40, Notts were indebted to a heavy shower which delayed Yorkshire's charge. The resumption saw Andre Adams smash a belligerent 39 from just 17 deliveries before hitting Patterson to long leg.
Ajmal Shahzad ended with an unbeaten 41 as Rashid finished the innings with the wicket of Harry Gurney, allowing visiting captain Andrew Gale to ask Nottinghamshire to have another go.
Both Hales and Lumb avoided being dismissed for a 'pair' but still fell cheaply, while Mullaney became Sidebottom's fifth victim of the day.
Patel made 37 from 43 balls but was caught one-handed by substitute fielder Richard Pyrah off the bowling of Liam Plunkett, leaving Hussey (22 not out) and Wessels (12 no) to steer the home county through to the close.
