Stephen Strasburg struggled in his 2022 debut, allowing seven runs in the Washington Nationals' 7-4 loss to the Miami Marlins on Thursday night.

The 33-year-old, who was pitching on the 13th anniversary of the Nationals selecting him with the No. 1 overall pick, lasted 4 2/3 innings.

"It felt good, and I'm excited to learn from it and get back out there for the next one," Strasburg said. "Fastball command could have been better in certain spots there. I felt the changeup was working pretty well. All in all, it's a place to start and try to build off of it."

The right-hander had not pitched in a Major League game since June 1 last year, spending much of the time recovering from surgery on July 28 to correct thoracic outlet syndrome, a compression of nerves, arteries or veins near the neck or armpit.
