Cheltenham claim second round spot
Bogey side Cheltenham dumped Oldham out of the FA Cup for the fourth time with a 1-0 win at Boundary Park.
Lewis Montrose, who turned 20 on Monday, celebrated by hitting a 23rd-minute winner - the on-loan Wigan midfielder's first career goal.
The Latics had been given a second chance in this replay after coming back from two goals down in the first game.
Fifteen places and 17 points separate the League One rivals, but Oldham could not find a way past the worst away defence in the country.
Cheltenham keeper Scott Brown made his first save to keep out a header from Dutch defender Stefan Stam in first-half injury time.
He saw more action after the break to deny close-range efforts from substitute Matt Wolfenden and Lewis Alessandra in the 48th and 57th minutes.
