Miami Marlins pitcher Janson Junk returned from an ankle sprain with a scoreless inning against the Astros, strengthening his case for a bullpen role in 2026.
The Miami Marlins got some good new on Saturday when right-handed pitcher Janson Junk made his spring debut after spraining his ankle on Feb. 17, during camp.
A few days later, the team was worried that Junk would hurt his ankle during warmups. The 30-year-old pitched against the Houston Astros in the Grapefruit League and looked great. In the Marlins' 5-4 loss, Junk pitched an inning of relief without giving up a run, allowing only one hit, striking out two batters, and not walking anyone.
For a pitcher who had to wear a protective boot during spring training because of a Grade-1 right ankle sprain, just getting back on the mound was a good sign. But Junk's performance showed that the injury probably won't last long enough to stop him from trying to make the team.
The ankle injury occurred early in camp during dynamic warmups, prompting some concern for a short time about whether Junk would be able to play at the start of the season. Even small problems can mess up a pitcher's preparation during spring training, which is mostly about building innings and improving mechanics.
In the last few weeks, Junk had been making progress in his throwing program, slowly increasing his workload until he was finally given the green light to play in a game. The trip on Saturday was the last stop in that process.
More importantly, Junk seemed at ease on the mound. His ability to attack hitters right away and get two strikeouts shows that the ankle problem hasn't changed his mechanics or balance, which can happen with lower-body injuries.
Junk had a small chance of making the Marlins' starting rotation when he first got to camp, but the early injury probably made that harder. He couldn't build up the multi-inning workload that rotation candidates usually need in the spring because he lost time.
Junk is still a strong candidate for Miami's Opening Day roster, though.
He quietly became one of the team's more flexible pitchers last season. In 2025, Junk pitched for the Marlins 21 times, starting 16 games. He had a 4.17 ERA and a strong 3.14 FIP. The numbers behind the scenes showed he was better than his ERA suggested, especially in limiting hard contact.
That ability to do different things could make him useful as a reliever.
If the Marlins decide to keep Junk in a long relief role, he could be a link between the bullpen and the rotation. He could pitch multiple innings when needed or fill in for spot starts during the long season.
The game on Saturday was only a small sample, but it gave us the most important piece of information: Junk looks healthy again, and Miami can keep monitoring how he fits into its pitching plans for 2026.
