Fabio Fognini apologized to fans after a disappointing loss to World No. 164 Joris De Loore in the semifinals of the 2023 Zug Challenger.
The Belgian surprised Fognini in straight sets in Zug, winning after just over an hour, 7-6(3), 6-1.
"Sad about my performance this morning! Sorry. Thanks for the nice week you give us," Fognini wrote (via his Instagram story).

The 36-year-old Italian didn't convert a break point in the first game of the match and then failed to capitalize while serving for the set at 6-5. The 30-year-old Belgian broke back, took the tie-break, and then lost just one game in the third set to book himself a place in the final of the Zug Challenger.
Fabio Fognini previously defeated Kilian Feldbausch, 6-4, 6-2, in the first round, Aziz Dougaz, 1-6, 7-6(5), 6-0, in the second round, and Jakub Mensik, 6-4, 6-2, in the quarterfinals at the Swiss tournament.
It was the first tournament in which Fognini has managed to get three victories in a row in 2023, his second tournament back after recovering from an injury that forced him to miss Wimbledon.
As for Joris De Loore, he didn't manage to win the title in Zug, as he lost to the Frenchman Arthur Rinderknech, 6-3, 3-6, 4-6, in the final.
Fabio Fognini to face Andrea Collarini in the first round of the 2023 San Marino Challenger
