YORKSHIRE are on the brink of defeat against Nottinghamshire at Trent Bridge.
At lunch on day four, the home side are 149-4, requiring another 25 for victory.
Opener Ben Slater has 64 and wicketkeeper Tom Moores is unbeaten on one.
Yorkshire took three wickets in the morning session after Notts began the day on 42-1.
First to go was Ben Duckett, moments after bringing up an 80-ball half-century, when he dragged on an attempted cover-drive off Jordan Thompson.
Duckett added 98 for the second-wicket with Ben Slater and his departure left the hosts 107-2.
Slater - dropped on 15 in the day’s third over by wicketkeeper Harry Duke off Ben Coad, diving in front of first slip Tom Kohler-Cadmore - reached his fifty from 83 balls with nine fours.
Notts slipped to 130-3 when first innings centurion Joe Clarke skied spinner Dom Bess to Kohler-Cadmore at mid-off to depart for 10, and then to 143-3 when Coad produced a fine ball to bowl Steven Mullaney for nine past the outside edge.
