The fourth tournament day of the Bitpanda Hamburg Open almost started with a surprise: Lucky loser Vitaliy Sachko from Ukraine took the first set from Flavio Cobolli in the first match of the day on the center court on Tuesday and earned the loud ovations of the fans. In the end, the Ukrainian lost 7:5, 2:6, 2:6, but the sympathy of the Hamburg crowd was assured after 2:37 hours of fighting.

Justin Engel has long since become a fan favorite at the Rothenbaum. The 17-year-old German top talent defeated Jan-Lennard Struff in the singles on Monday evening and celebrated a 6:7, 6:4, 10:5 victory over the Americans Nathanial Lammons and Jackson Withrow in the doubles alongside Max Hans Rehberg on Tuesday. In the decisive match tie-break, the atmosphere on Court M2 literally exploded.

Those who had made their way to Center Court saw the second seed Frances Tiafoe struggle against the Chinese player Yunchaokete Bu in the first set. After an early break, Tiafoe caught himself, fought off a second break and ultimately deserved to progress to the next round after winning 7:5, 6:2. There, the Frenchman will meet Roberto Bautista Agut on Wednesday.
