Pittsburgh Pirates Pitcher Mitch Keller Out for the Season with Arm Injury
What Happened?

News Date: August 3, 2026

Who Is Mitch Keller?
- Position: Starting Pitcher
- Throws: Right-handed
- Team: Pittsburgh Pirates
- Role: One of the team’s main starting pitchers
Think of a starting pitcher like the quarterback of baseball’s defense — they begin the game on the mound and try to stop the other team from scoring.
What Is the Injury?
Keller has a right arm teres major muscle injury.
ELI5 Explanation:
The teres major is a small but important muscle in your upper arm/shoulder area. It helps you rotate your arm and bring it down — movements that are super important for throwing a baseball.
Imagine trying to throw a ball as hard as you can with a sore muscle right where your arm meets your shoulder. That’s what Keller is dealing with.
What Does "60-Day Injured List" Mean?
This is a special list in Major League Baseball (MLB). Here’s how it works:
- Player is removed from the active 26-man roster (the players who can play in games)
- Team can replace them with another player
- Player cannot return for at least 60 days
- In Keller’s case, 60 days takes us past the end of the regular season
Important Callout:
Keller will NOT pitch again this regular season. The earliest he could return would be the playoffs — if the Pirates make it that far.
Who Is Replacing Him?
The Pirates have recalled Brandon Eisert from the minor leagues to take Keller’s spot on the active roster.
About Brandon Eisert:
- Position: Pitcher
- Throws: Left-handed
- Previous Team: Minor league affiliate (Triple-A Indianapolis)
- Role: Will help fill the gap in the pitching staff
What "Recalled" Means:
Eisert was playing for the Pirates’ minor league team. Now he’s been "called up" to the big leagues to help the main team.
Why This Matters for the Pirates
| Impact Area | What It Means |
|---|---|
| Starting Rotation | One less experienced starter for the final two months |
| Bullpen Pressure | Other pitchers may need to throw more innings |
| Playoff Hopes | Harder to win games without a top starter |
| Team Morale | Tough blow for a team fighting to stay competitive |
What Happens Next?
For Mitch Keller:
- Rest and rehab the injured muscle
- Work with trainers on recovery exercises
- Gradual throwing program once healed
- Target: Ready for Spring Training 2027
For the Pirates:
- Brandon Eisert joins the major league team
- Other pitchers step up to cover innings
- Front office may look for trades or free agents
- Keep winning to stay in playoff race
Summary
- Mitch Keller (starting pitcher) is done for the regular season
- Injury: Right teres major muscle (shoulder/upper arm area)
- Placed on 60-day injured list on August 3, 2026
- Brandon Eisert (lefty reliever) called up to replace him
- Pirates must adjust their pitching plans for the final stretch
FAQ
What is the teres major muscle?
It’s a small muscle connecting your shoulder blade to your upper arm. It helps rotate your arm inward and pull it down — crucial for the throwing motion.
Can Keller come back for the playoffs?
Technically yes — the 60-day IL only covers the regular season. But realistically, a teres major injury for a pitcher usually takes months to heal properly. Don’t count on it.
Who is Brandon Eisert?
A left-handed pitcher who was playing in Triple-A (the highest minor league level). He’ll likely work out of the bullpen (relief roles) rather than start games.
How many games will Keller miss?
The regular season ends in late September/early October. From August 3, that’s roughly 50–60 games — about a third of the season.
Will the Pirates make a trade to replace Keller?
They might, but MLB trade rules make August trades complicated. They’re more likely to use pitchers already in their organization (like Eisert) and ask current starters to go deeper into games.
