Lancashire 301 for 9 dec. (Jennings 64, Bohannon 53) drew with Glamorgan 344 (Lloyd 78, Douthwaite 61, Taylor 58)
Honours finished even at Emirates Old Trafford in the LV=Insurance County Championship clash between Lancashire and Glamorgan with both sides collecting 14 points each from a rain-affected draw.
With Lancashire restarting on 22 for the loss of no wickets in reply to Glamorgan's 344, Michael Neser immediately began posing questions and quickly dismissed Alex Davies with a beauty which the opener could only feather behind for 15, adding just one to his overnight score.
Luke Wells came to the crease for his home debut and together with Jennings, the pair compiled a second-wicket partnership of 62, before the former Sussex batter skied spinner Andrew Salter to Dan Douthwaite at mid-on for 30.
In-form Jennings continued to press his England credentials as he cruised to a third successive half-century off 163 balls with a delightful off drive for four off Neser.
It was a shock then, when he gifted Salter a second wicket after slicing a drive to Callum Taylor at backward point to depart for 64.
Batting had been slow-going by this point but Liam Livingstone's introduction brought an immediate injection of entertainment with the tall Cumbrian getting off the mark with a towering six off Salter.
At the other end, Bohannon followed suit with Marnus Labuschagne's legspin also targeted as the run rate increased.
The 50 partnership came off just 57 balls but Livingstone's frenetic innings ended soon after when he holed out to Joe Cooke on the leg side boundary off Timm van der Gugten for 25 with Lancashire on 183 for 4.
Bohannon brought up his third half-century of the season from 105 balls but fell soon after when cutting Taylor to Salter at backward point for 53.
Twelve overs were lost through a combination of rain and bad light and when play was resumed at 4.35pm, Lancashire began to throw the bat with Dane Vilas caught at third man by Cooke off Douthwaite for 25 and Luke Wood top-edging the same bowler to keeper Chris Cooke for 28.
Saqib Mahmood hit a couple of boundaries before he fell to a stunning one-handed caught-and-bowled by Neser, with Danny Lamb the ninth wicket to fall clean bowled by David Lloyd for 22 which brought England's James Anderson to the crease.
Together with Matt Parkinson, who finished unbeaten on 16, the last-wicket pair scrambled their way to a batting point with Anderson finishing on 5 not out as Lancashire passed 300 and declared on 301 for 9, bringing the game to a close.
