Yorkshire were left struggling to keep their heads above water after another day of fluctuating fortunes in the LV= County Championship Roses clash at Headingley.
Set a victory target of 284, the hosts slumped to 136 for six at the close of the third day, 148 runs behind title-chasing Lancashire.
The visitors had earlier been indebted to their ninth-wicket partnership of Sajid Mahmood and Kyle Hogg, who combined for 80 runs to set a competitive score after the visitors were left wobbling on 87 for eight.
Both players completed half-centuries in what could yet prove to be a match-winning stand.
Yorkshire began their run-chase following an early tea, with Jacques Rudolph (35) and Joe Root (14) calming home nerves with the best opening stand of the match.
Rudolph cover-drove and edged Glen Chapple for boundaries and Root hooked Tom Smith for four but the colt was put down by wicketkeeper Gareth Cross on 12.
Moments later, Chapple had his man, Root’s edge held by Paul Horton at first slip.
Rudolph straight-drove Mahmood for four while Anthony McGrath (19) played some good strokes until both got out in consecutive overs to give Lancashire the upper hand. McGrath, moving forward, was lbw to Kyle Hogg, and Rudolph also stepped in front against Mahmood.
Skipper Andrew Gale and Jonny Bairstow each got off the mark with first-ball boundaries but with 24.4 overs gone the umpires took the players off for bad light.
