Sky Blues on level terms with the Latics at half time after goalless first 45 minutes at Boundary ParkCoventry City head into the half time break on level terms with Oldham Athletic after a goalless first half at Boundary Park.
City boss Steven Pressley opted to make tow changes to his starting line up from the team that lost 2-1 to Swindon Town on Good Friday, bringing in Nathan Eccleston and Anton Robinson to replace Nathan Delfouneso and Conor Thomas for the clash with the Latics.
For all of the pace and frenzy of the opening stages it took 16 minutes for the first effort of the day to materialise and it came to former Sky Blue Jonson Clarke-Harris.
A deep cross picked out the striker to loop a header which looked as though it would drop just inside the far post until Joe Murphy tipped it over his bar at full stretch.
Clarke-Harris then went just as close four minutes later with a free kick after drawing a foul from Carl Baker just over 20 yards out. His stinging effort curled around the bottom of City's wall but smacked the face of the far post with Murphy sprawling down low in an attempt to get a hand to it.
Callum Wilson went close in the only other real chance of the first 45 minutes when he picked up a clever short ball from Baker and fired from a tight angle after 34 minutes only to see his effort deflected into the side netting.
