RIO DE JANEIRO, Sept. 17 -- Peru international striker Paolo Guerrero scored just his sixth goal of the Brazilian Serie A season on Sunday as Flamengo moved back into the top four with a 2-0 victory over Sport Recife.

Guerrero struck in the ninth minute before Everton Ribeiro added another goal for the hosts in second-half injury time.

The result at Estadio Luso Brasileiro lifted Flamengo to 38 points from 24 matches, 15 points behind leaders Corinthians, who earlier beat Vasco da Gama 1-0.

In Porto Alegre, striker Arthur scored just before halftime as Chapecoense climbed out of the relegation zone with a surprise 1-0 away victory over Gremio.

It meant Chapecoense moved up to 14th while Gremio remained second, 10 points behind Corinthians.
