The Nigeria international put Leganes ahead in the third minute, nodding home Dani Ojeda’s corner.
Rosales got the second in the 12th minute, while Jose Armaiz added the third five minutes before the break.
Eibar pulled one back in stoppage time, through Quique.
Omeruo was on for 90 minutes in the game.
The centre-back scored one goal in 23 league appearances for the Leganes last season.
The Nigeria international is expected to leave the club this summer following their relegation to the Segunda Division last season.
