Ronnie O'Sullivan took Chang Bingyu apart 4-1 to race into the third round of the Scottish Open.
A focused O'Sullivan started in fine style, with a quick break of 134 to clear the table, and followed that up with a 78 in the third and a half-century in the final frame.
Chang put up more of a fight in the second but ultimately failed to capitalise on the errors that had opened up the opportunity to him.
