Pericles Chamusca made the perfect start as manager of Oita Trinita as the relegation-haunted club stunned Urawa Reds 2-1 away while Gamba Osaka moved four points clear at the top of the J. League first division on Saturday.
The Brazilian Araujo, who is the league's top scorer, grabbed a hat trick to lift Gamba to a come-from-behind 4-2 win over Sanfrecce Hiroshima while Jubilo Iwata leapfrogged Urawa into third place with a 2-0 win at home to Omiya Ardija.
Gamba leads the table with 47 points from 23 games, four clear of idle Kashima Antlers, who travel to Kawasaki Frontale on Sunday. JEF United Chiba plays Tokyo Verdy in Sunday's other fixture.
