Northamptonshire 279 and 472 for 8 dec (McManus 168, Vasconcelos 99, Procter 98) drew with Glamorgan 490 (Crane 56*, Procter 3-51) and 207 for 8 (Labuschagne 64, Patterson-White 3-101)
Having been 211 runs behind on first innings, Northamptonshire had nine catchers around the bat in the closing overs as they pushed for the win.
Glamorgan finished on 207 for eight with Northamptonshire two wickets short of victory.
In the absence of Harris, Labuschagne came on to bowl seam and he generated some decent pace, albeit without managing a breakthrough. He also sent down a few overs of leg spin once the shine was off the new ball.
The first wicket of the day came in the second session when Timm van der Gugten trapped Procter for 98, the second Northamptonshire batter to get out in the nineties in this innings after Ricardo Vasconcelos fell for 99 late on day three.
Lewis McManus had past his hundred from 150 balls just before the fall of Procter’s wicket and he looked to be more attacking once he had reached his milestone, scoring at better than a run a ball as he looked to set a target for Glamorgan to chase.
McManus passed 150 for the first time in first class cricket and took four consecutive sixes off Crane in the last over before Northamptonshire declared to leave Glamorgan needing to score at seven an over to win.
Glamorgan were 30 for one at the tea break and after the interval they made a real push to keep the required rate under control, but that desire for quick runs brought about the demise of Billy Root when Labuschagne called him through for a very sharp single and both batters ended up at the same end.
Carlson and Labuschagne kept up the intensity in their stand of 62 from 57 balls. Carlson was bowled by Alex Russell when he attempted a big shot to the shorter boundary on the Grandstand side of the ground.
Labuschagne looked very keen to secure a win in his last home game in the Championship this season but he chipped a catch to point off the bowling of Liam Patterson-White for 64.
Chris Cooke continued to attack but he fell for 27 looking to hit Russell over long off. Mason Crane was dismissed for a duck and Harry Podmore was bowled for 1 as Northamptonshire continued the late push to complete the comeback but Timm van der Gugten saw out the last over to secure the draw.
