Thrilling quarter-final matches guaranteed

The four quarter-final matches will be played on Friday at the BOSS OPEN. Including local hero Jan-Lennard Struff, as well as last year's winner Frances Tiafoe.

It is also Tiafoe who kicks off the day at 11 a. on the center court. The American, seeded No. 4, will face Jack Draper (6) from Great Britain.

Jan-Lennard Struff will make his appearance directly afterwards. The player from Warstein will face American Brandon Nakashima, who has yet to drop a set during the tournament. Struff is counting on the support of the spectators in this duel. "The support is outstanding, it's wonderful to play here."

Not before 2.30 pm, two-time Stuttgart winner Matteo Berrettini will face James Duckworth. On Thursday, the Australian qualifier upset US youngster Ben Shelton, seeded No. 2, in three sets.

To close out the day, Lorenzo Musetti (ITA) and Alexander Bublik (KAZ) will battle it out for the last remaining semi-final spot.
