Levante jump up league with win
The Nigeria international opened the scoring two minutes before halftime when he latched on to Nabil El Zhar's long pass over the defense and poked it under goalkeeper Duda Aouate.
Martins then combined twice with Ruben Garcia on the break for Garcia to double the lead in the 48th, before David Navarro headed in Levante's third goal in the 55th.
Martins helped cap the win three minutes later when he stole the ball inside Mallorca's area and passed for Navarro to assist Vicente Iborra.
Levante's victory lifted it into sixth place.
Mallorca is in danger of falling into the relegation zone after its 10th game without a victory.
