Great Britain's Jack Draper beat Vit Kopriva to reach the last 16 of the Italian Open but his frustration boiled over during a straight-set win.
Although the fifth seed won 6-4 6-3 in Rome, he was made to work hard to close out the victory and at one point hit the court multiple times with his racquet.
Draper, who came into the tournament on the back of reaching the Madrid Open final, held serve throughout and took the first set in 41 minutes, saving one break point.
But it was by no means plain sailing in the second as Czech qualifier Kopriva saved four break points to cut his deficit to 3-2.
