You know how some relief pitchers just seem to hang around forever? They aren't usually the guys hitting 103 on the radar gun or starring in every highlight reel. They're the grinders. The ones who show up, throw strikes, and somehow survive a decade of roster cuts.
That brings us to Justin Wilson Red Sox fans saw in 2025.
It was a weird year for the Boston bullpen. Honestly, it's always a little chaotic at Fenway, but Wilson was one of those "wait, he's still playing?" guys who actually ended up being a backbone for Alex Cora. After bouncing around basically half the league—Pittsburgh, Detroit, both New York teams, Chicago, and Cincinnati—Wilson landed in Boston on a one-year, $2.25 million deal.
Most people thought he was just depth. A warm body to bridge the gap to the high-leverage guys. Instead, he turned back the clock.
The Surprising Reality of Justin Wilson in Boston
When Craig Breslow signed Wilson, the analytics crowd was a bit skeptical. The lefty was 37 and coming off a 2024 season in Cincinnati where he posted a 5.59 ERA. Not exactly "get me out of my seat" numbers. But the Red Sox saw something in his underlying metrics, specifically a chase rate that ranked in the 95th percentile.
They were right.

Wilson didn't just survive; he excelled. He finished the 2025 campaign with a 3.35 ERA over 61 appearances. That’s a massive workload for a guy his age. He struck out 57 batters in 48.1 innings. Basically, he became the primary southpaw bridge before getting the ball to the closer.
What Most People Get Wrong About His Performance
There's this narrative that Wilson is just a lefty specialist. That’s old-school thinking. In 2025, while lefties only managed a measly .212 batting average against him, Wilson had to navigate plenty of right-handers too.
It wasn't always pretty. Righties slashed .306/.382/.439 against him. If you're looking for why he struggled down the stretch—allowing six runs in his final six games—that’s your answer. When teams stacked righties against him late in the season, the cracks started to show.
Still, look at his FIP (Fielding Independent Pitching). It was 2.95. That is his best mark since 2015. For a veteran to find that kind of efficiency at 37 is practically unheard of in today's game.
Why the Retirement Rumors are Heating Up
Now we’re in 2026, and the conversation has shifted. Justin Wilson Red Sox jerseys are still in the clearance bins, but the man himself might be done.

League insiders, including Ken Rosenthal, have reported that Wilson is seriously considering hanging up the cleats. It makes sense. He’s 38. He’s made 648 career appearances. Only eight active pitchers have more than him.
But there is a catch.
Wilson is reportedly only interested in returning if he gets a "fair deal" with a legitimate World Series contender. He’s won a College World Series with Fresno State back in 2008, but that MLB ring has eluded him. He doesn't want to just eat innings for a 70-win team. He wants a shot at the trophy.
Could a Return to Boston Happen?
The Red Sox bullpen for 2026 is still a work in progress. They’ve got Aroldis Chapman at the back end now, but they are thin on reliable lefties behind him.
Management has reportedly "checked in" on Wilson this offseason. They're also looking at names like Cionel Perez and Danny Coulombe. Honestly, Wilson knows the system, Cora trusts him, and he’s already proven he can pitch in the AL East pressure cooker.

Key Stats from Wilson's 2025 Campaign:
- ERA: 3.35
- Strikeouts: 57
- Innings Pitched: 48.1
- FIP: 2.95 (elite territory)
- Salary: $2.25 million base plus incentives
The "Invisible" Win
One of the funniest things to happen during Wilson's tenure in Boston was a game against the Twins.
Wilson actually earned a "Win" without facing a single batter. He came into a tie game with two outs and a runner on first. Before he could even throw a pitch to the hitter, the runner was caught stealing. The Red Sox took the lead in the next half-inning, and Wilson was replaced.
He literally became the 28th pitcher in MLB history to record a win without facing a hitter. It’s the ultimate "work smart, not hard" moment.
Final Verdict on the Veteran Southpaw
Justin Wilson isn't going to the Hall of Fame. He’s a "guy." But he’s a guy every winning team needs. If he retires now, he walks away with a 3.59 career ERA and over 600 strikeouts. That’s a hell of a career for a 5th-round pick.
If you're a Red Sox fan, you should appreciate what he gave the team last year. He provided stability when the bullpen felt like it was made of glass.
Next Steps for Red Sox Fans:
Keep a close eye on the transaction wire through February. If Wilson hasn't signed with a contender like the Dodgers or Braves by the time pitchers and catchers report, his retirement is likely official. However, if Boston fails to land a high-end lefty in the coming weeks, expect the rumors of a Wilson reunion to get much louder.
