Ipswich moved back up to second place in the Sky Bet Championship following a 2-0 win at Plymouth.
Kieffer Moore sealed Town’s win after Conor Chaplin’s shot was deflected in by home defender Brendan Galloway in the 63rd minute.
Argyle’s top scorer Morgan Whittaker forced an early save from Ipswich goalkeeper Vaclav Hladky.
The keeper palmed the ball to Darko Gyabi, but the Leeds loanee sent a fierce low drive just wide of the upright from the edge of the box.
Ipswich countered, with target man Moore’s header bringing a 14th-minute save from Argyle goalkeeper Conor Hazard.
Hladky did well to punch away Adam Randell’s inswinging corner as the home side again tried applying pressure on their high-flying visitors.
Omari Hutchinson saw a goal-bound shot blocked after being teed up by impressive midfielder Jeremy Sarmiento.
In the 35th minute, Whittaker’s 25-yard shot was blocked but fell to striker Ryan Hardie on the edge of the box and his rising drive flew just over.
And shortly afterwards Ipswich defender Luke Woolfenden made a brilliant clearance off the line to keep out Mickel Miller’s volley.
The half ended with Ipswich pressing and Leif Davis’s corner from the right needed to be cleared at the near post by a defender’s diving header.
Whittaker tried an audacious chip from 40 yards after spotting Hladky off his line early in the second half, but the ball flew just over.
Moore was again denied by Hazard in the 55th minute as the striker headed goalwards from Davis’s far-post cross from the left.
Hutchinson sent a curling shot just wide of the far upright after 56 minutes with Hazard beaten and then forced a superb diving save from the keeper on the hour.
The ball looped up to Chaplin and his header was helped on – and over the bar – by Moore.
Chaplin benefited from a huge slice of fortune three minutes later as his 18-yard shot deflected off Galloway, completely wrong-footing Hazard, with the ball spinning into the opposite corner of the goal.
Ipswich doubled their lead in the 74th minute as Davis sent over another cross from the right. Cameron Burgess headed the ball on to Chaplin and Moore finished with a half-volley at the far post.
Miller went closest for Plymouth with a 78th-minute shot on the run from outside the box that beat Hladky but smashed off the foot of a post and across the face of goal.
