China's Zhang Zhizhen missed two match points and suffered a first-round exit at the ATP Italian Open on Wednesday, falling to Germany's Daniel Altmaier 4-6, 7-6 (3), 6-4.
Zhang, who entered the main draw using a protected ranking, had won their only previous meeting in 2023. In their latest encounter, Zhang broke in the third game of the opening set and maintained his advantage to take the set 6-4.
In the second set, Zhang broke in the fifth game to move ahead 3-2. Although Altmaier broke back in the following game, Zhang responded immediately with a love break in the seventh game. Zhang then had two match points in the ninth game but failed to convert either before being broken in the 10th as the German forced a tiebreak. Altmaier took control in the tiebreak, winning it 7-3 to level the match.
