Senegal's Demba Ba scored Istanbul Basaksehir's only goal while Mali's Mustapha Yatabare grabbed the equaliser that earned Sivasspor 1-1 draw in a Turkish Super Lig match.
Following a goalless first-half, Ba broke the deadlock at the Sivas 4 Eylul Stadium for the visitors in the 66th minute.
The effort took the ex-Chelsea striker's tally to six goals after 15 league outings this term.
A late equaliser from Yatabare saved Sivasspor from defeat and moved them to the summit of the league table.
The Malian forward is the highest-scoring player in Riza Calimbay's team this season, and has returned nine league goals in 20 games.
