Call-Up Comes with Roster Expansion
The Baltimore Orioles are making a move that fans have waited years to see. Outfielder Heston Kjerstad is heading back to the big leagues this Tuesday. The club is calling him up as MLB rosters expand for the final stretch of the season. Top prospect De León, the No. 7 overall pick, is joining the squad too. This isn’t just a routine lineup tweak. It signals a return for a player whose career nearly ended before it truly began.
Kjerstad has been tearing it up at the minor league level. He hit .289 with a .This year at Triple-A Norfolk, the on-base-plus-slugging percentage stands at 799, according to RotoBaller MLB. The numbers got even better down the stretch. He posted a .301 average with an .889 OPS since July. Those stats prove he is ready for the jump back to the majors. The organization sees a hitter who can contribute right now.
A Rocky Road Back to the Field
Getting here was far from easy for the former first-rounder from Arkansas. Myocarditis diagnosed in 2024 caused a massive hit to his development. That wasn’t the only blow. A pitch striking his helmet resulted in a concussion he then suffered. These injuries stalled his momentum and kept him away from the game he loves.
The timeline for his return has been complicated by further issues. Although murky circumstances surround it, Kjerstad also missed most of 2025. Despite these setbacks, he is finally ready to take the field. The 2026 season debut in the big leagues for Kjerstad will occur when he gets into a game for the O’s. His presence in the lineup is a victory over adversity. The stats from his previous time in Baltimore show he has potential, but the injury history makes this moment special. He has combined to hit just .218/.284/.365 with a .Since making his major-league debut in 2023, Baltimore has seen 106 games, 314 plate appearances, 649 OPS, 10 homers, 36 RBI, 18 walks, and 88 strikeouts.
The Orioles need every edge they can get as the season winds down. Kjerstad’s recent hot streak at Triple-A Norfolk cannot be ignored. A .889 OPS since July is not a fluke. It shows a hitter who has adjusted to the minor league pitching and is finding his rhythm. The team is taking a calculated risk by bringing him up now. He is a left-handed hitter who offers a different look at the plate. The organization is betting that his health is stable enough to handle the grind of a full major league schedule.
This call-up also highlights the depth the Orioles have built. They aren’t just relying on their stars. They are giving a chance to a player who has fought through serious medical issues. The 27-year-old left-handed-hitting outfielder has a story that resonates with any fan who has seen a career derailed by bad luck. His return proves that persistence pays off. The club is willing to give him the stage to prove he belongs. If he can translate his recent minor league success to the big leagues, he could be a key piece in the lineup for years to come.
The roster expansion happens on Tuesday. That is the concrete date when these moves take effect. Kjerstad and De León will officially be part of the 40-man roster moving forward.
