Plymouth secured the League One title with a 3-1 win at Port Vale on the final day. Argyle finished the season three points clear of second‑placed Ipswich, who were held to a 2-2 draw at Fleetwood, as they came from behind to win at Vale Park and move on to 101 points. Plymouth fell behind three minutes in as James Plant slotted home for the hosts, but Adam Randell levelled before Joe Edwards put them in front and Finn Azaz added a third. Ipswich scored their 100th and 101st league goals of the season but it was not enough as their former player Jack Marriott scored twice for the hosts. Freddie Ladapo brought up the century of goals to put them ahead in the 49th minute. Marriott levelled 12 minutes later, and then again after Marcus Harness got a second for Ipswich. Ipswich frustrations boiled over late on as Harry Clarke was booked twice inside seven minutes to see red in stoppage time. Derby missed out on a playoff place as they went down 1-0 at Sheffield Wednesday, allowing Peterborough to snatch sixth place with a 2-0 win at Barnsley. It all went wrong for Derby late in the first half when the captain, Curtis Davies, was sent off for a foul on Marvin Johnson in the box, with Michael Smith converting the penalty. Peterborough took full advantage as goals from Jonson Clarke-Harris and Jack Taylor delivered victory at Oakwell, setting up a playoff semi-final against Wednesday. Barnsley will face Bolton, who got ready for the playoffs with a 3-2 win at Bristol Rovers. Shola Shoretire’s goal was cancelled out by Luca Hoole but Daniel Nlundulu and Aaron Morley put the Trotters in command before John Marquis pulled one back late on. Cambridge secured their League One future with a 2-0 win against basement boys Forest Green. They had been in the relegation zone since January but climbed out on the final day with goals from Harrison Dunk and Sam Smith – their victory condemned MK Dons, who were held to a goalless draw at Burton Albion. Morecambe are also heading to League Two after going down 3-2 at Exeter, who were inspired by a hat-trick from on-loan Fulham forward Jay Stansfield. Cole Stockton had cancelled out Stansfield’s first, but the home-town boy would have the last word. Accrington’s relegation, all but mathematically certain before kick-off, was confirmed despite a 2-1 comeback win at Oxford, who survived by two points. John Coleman’s side always needed an highly improbable goal swing, but went down fighting as Korede Adedoyin and Aaron Pressley scored to cancel out Billy Bodin’s opener. Alfie May’s late strike earned Cheltenham a 2-2 draw with Charlton, who had led twice. Aidan Keena cancelled out Scott Fraser’s opener, with Jack Payne putting Charlton back in front before May struck at the death. Paddy Lane’s first Portsmouth goal earned them a 2-2 draw at home to Wycombe. Marlon Pack cancelled out Garath McCleary’s goal for Wanderers late in the first half, while Lane’s effort was needed after Lewis Wing put the visitors back in front with a spectacular long-range effort. Rounding off the action in the division before playoffs take centre stage, Matty Virtue’s 73rd-minute strike gave Lincoln a 1-0 win against Shrewsbury.
