Ghana striker Richmond Boakye Yiadom registered his first goal of the season on Saturday which took Sassuolo to the summit of the Serie B table.
The 19-year-old scored in the 32nd minute against Ascoli.
Boakye Yiadom is loan at the Serie B leaders from Juventus who acquired him from Genoa just this summer.
Last season, the young striker was at Sassuolo on a season-long loan deal from Genoa and finished the season with 12 goals.
That performance prompted the Old Lady to tie him down.
Boakye Yiadom has made two appearances for the Black Stars of Ghana and scored one goal in the process.
