Stephen Strasburg is not pitching because he has retired from Major League Baseball. The former Washington Nationals ace officially stepped away in April 2024, after nerve damage linked to thoracic outlet syndrome made it impossible for him to pitch at a big-league level. His last game came on June 9, 2022.
For many fans, the question still lingers. Strasburg was the 2019 World Series MVP and signed a $245 million contract just weeks later.
Then he nearly vanished. Here is the full story of why one of the most talented pitchers of his generation is no longer on the mound, and why he will not be coming back.
Who Is Stephen Strasburg?
Stephen Strasburg was one of the most hyped pitching prospects in baseball history. The Nationals took him first overall in the 2009 draft out of San Diego State University. His debut in June 2010 became an instant legend when he struck out 14 Pittsburgh Pirates.
The hype came with setbacks from the start. Within three months of that debut, Strasburg needed Tommy John surgery and missed most of 2011. In September 2012, Washington famously shut him down to protect his arm, even as the team headed into the playoffs.
The payoff finally arrived in 2019. Strasburg went 18-6 and led the National League in both wins and innings pitched, with 209. In October he was nearly untouchable, going 5-0 with a 1.98 ERA and winning Games 2 and 6 of the World Series against the Houston Astros. He was named World Series MVP as Washington won its first championship.
That December, he opted out of his old deal and re-signed with the Nationals for seven years and $245 million. It looked like a fair reward for a franchise icon. Instead, it became one of the most painful contracts in recent baseball history.
The Injury That Changed Everything: Thoracic Outlet Syndrome
The main reason Stephen Strasburg is not pitching is thoracic outlet syndrome, often shortened to TOS. The thoracic outlet is the narrow space between the collarbone and the first rib.
Nerves and blood vessels pass through it on their way to the arm, and when that space gets too tight, they get compressed.
For a pitcher, the nerve-related form of TOS is especially damaging. Symptoms include numbness, tingling, weakness and pain that run down the arm and into the hand.
The repeated, violent overhead motion of pitching can make it worse, and surgery to relieve the pressure often involves removing the first rib.
Strasburg’s troubles began in 2020, when carpal tunnel neuritis in his right hand limited him to two starts and required surgery. In 2021, shoulder inflammation and a neck strain kept sending him back to the injured list. Doctors eventually diagnosed TOS, and he had surgery in July 2021.
Recovery from TOS surgery is unpredictable. Some pitchers return to form, while others, such as Matt Harvey, never regain their old stuff. Sadly, Strasburg would end up in the second group.
The Failed Comeback in 2022
Strasburg reported to spring training in 2022 hoping for a fresh start. He worked his way back and returned on June 9, 2022, against the Miami Marlins. It was a rough outing: he lasted 4 2/3 innings and gave up seven earned runs.
Shortly afterward he was back on the injured list, this time with a stress reaction in his ribs. Nobody knew it then, but that start would be the last game of his career.
The news only got worse. Later in 2022, reports surfaced that Strasburg was dealing with severe nerve damage, with symptoms that made even ordinary daily tasks difficult. In early 2023, he suffered another setback in his throwing program, skipped spring training and was moved to the 60-day injured list.
The numbers tell the story. After signing his $245 million deal, Strasburg made just eight starts and threw 31 1/3 innings, going 1-4 with a 6.89 ERA. In total, he threw only 528 pitches in the majors under that contract.
The Messy Retirement Saga
By the summer of 2023, it was clear Strasburg would never pitch again. In August, reports said he planned to retire, and the Nationals began planning a press conference for September. It never happened.
The holdup was money. Strasburg was still owed about $105 million through the 2026 season. Under baseball’s rules, a player who simply retires generally gives up the salary left on his contract, so both sides had to agree on terms first.
Reports said the team tried to change the original arrangement, under which he would have been paid in full. Nationals owner Mark Lerner then said the club would not host a retirement event. The standoff dragged into 2024, with Strasburg still technically on the roster.
Finally, on April 6, 2024, MLB listed him as officially retired. The two sides reached a settlement under which he would receive his remaining money, with part of it deferred.
In his statement, Strasburg said injuries no longer allowed him “to perform at a Major League level,” and he thanked his coaches, teammates, medical staff and Nationals fans.
Will Stephen Strasburg Ever Pitch Again?
No. As of October 2026, Stephen Strasburg remains retired, and there has been no sign of a comeback. Even before he retired, both Nationals general manager Mike Rizzo and his agent, Scott Boras, acknowledged that his pitching days were over.
Several reasons make a return unrealistic. He is now 38 years old and has not pitched in a major league game in more than four years. Most importantly, the nerve damage that ended his career is not the kind of injury that rest alone can fix.
The 2026 season was also the final year of his seven-year contract, so that chapter has now fully closed. His next milestone will likely be the Hall of Fame ballot, which he should first reach in 2028 under the five-year waiting rule.
His shortened career makes him a long shot, but his postseason heroics give him a résumé few pitchers can match.
Stephen Strasburg’s Legacy
Strasburg finished with a 113-62 record, a 3.24 ERA, 1,723 strikeouts and three All-Star selections across 13 seasons, all with the Nationals. Mike Rizzo, the general manager who drafted him, has placed him on the franchise’s Mount Rushmore.
His career also became a lesson in how fragile elite pitchers can be. Years before his final injury, broadcaster Tony Kornheiser nicknamed him “The Orchid,” a nod to both his brilliance and his fragility. Today, his $245 million deal is often cited as a warning about long, expensive contracts for pitchers in their 30s.
Still, none of that erases October 2019. For one magical month, Strasburg was the best pitcher in baseball, and he delivered the only World Series title in Nationals history.
Conclusion
So, why is Stephen Strasburg not pitching? Thoracic outlet syndrome and the severe nerve damage that followed ended his career.
After surgery in 2021, one painful comeback start in 2022 and a long contract dispute, he officially retired in April 2024.
He will not return to the mound. But his name will always be tied to the Nationals’ 2019 championship and one of the greatest postseason runs by a starting pitcher in modern baseball.
