Oxford United 1 Ipswich Town 0
A goal by David Smith - his third in 180 games - earned Oxford a precious win over Ipswich at the Manor Ground.
The visitors failed to clear a Bobby Ford corner and the ball rolled to the midfielder, who drove in through a crowded goalmouth.
Oxford them pulled off strikers Nicky Banger and Martin Aldridge for the last 20 minutes, brought on 18-year-old Welsh youth Rob Folland for his debut and their packed midfield stifled the visitors' late bid for an equaliser.
Neither side, who meet in the fourth round of the Coca-Cola Cup, impressed in a poor first half.
Kieron Dyer threatened Oxford with two dangerous crosses early on and only a brave save by on-loan goalkeeper Arjan Van Heusden denied Alex Mathie who dispossessed Les Robinson near goal.
Banger went close after 22 minutes when a weak punch at corner by Ipswich goalkeeper Richard Wright resulted in the striker swivelling and shooting too high.
Several minutes before the interval Mauricio Taricco, sent off in the match last year, was booked for a foul on Joey Beauchamp whose free-kick was headed against the crossbar by Banger.
Ipswich, who have never won a league match at Oxford, went agonisingly close to equalising after 56 minutes.
A Taricco through ball put full-back Mick Stockwell through and he forced the ball past the goalkeeper and post. Bobby Ford was inches from scoring for United on the hour with a low shot form an acute angle.
Ipswich never gave up after the setback and Mathie missed a sitter four minutes from the end.
Taricco again opened up the defence and the striker, with only Van Heusden to beat, lifted the ball over the keeper and the crossbar
