Carlos Tevez helped Boca Juniors to claim a 2-1 win over Quilmes on his return to the Argentine club.
The 31-year-old rejoined his hometown club last month, after spending the past 11 years playing in Europe.
Boca had taken the lead in the first half thanks to a goal from Sebastian Palacios and Jonathan Calleri doubled their lead with a chipped rabona strike.
Alexis Canelo pulled a goal back for the visitors minutes later, but Boca held on to ensure a winning return for Tevez.
The victory leaves Boca one point clear at the top of the Argentine Primera Division.
