Nick Kyrgios’ return to action at the Stuttgart Open ended with a second-round loss to Japanese qualifier Sho Shimabukuro.

Kyrgios, 31, secured his first tour-level win since March 2025 by defeating eighth seed Corentin Moutet in his opening match in Germany on Tuesday.

That was his first singles match since losing in the first round in Brisbane on 5 January.

Wimbledon 2022 runner-up Kyrgios, who has struggled with knee and wrist injuries in recent years, received a wildcard for the grass-court tournament in Stuttgart.

He made a promising start, taking the the opening set against Shimabukuro, but his 104th-ranked opponent edged a second-set tie-break and went on to clinch a 4-6 7-6 (7-5) 6-4 victory.

There was no play at the Queen’s Club in London on Thursday because of bad weather.
