The Atlanta Braves are facing a tough roster decision as closer Raisel Iglesias prepares to return from the injured list on Tuesday. Iglesias, who landed on the 15-day IL after sleeping on his shoulder the wrong way, is expected to be activated without needing a rehab assignment—a welcome boost for a bullpen that’s been stretched thin.

But with his return comes an uncomfortable roster crunch. One name that’s increasingly being mentioned as a potential casualty is left-handed reliever Aaron Bummer, who signed a $13 million deal but has struggled out of the gate this season. While Bummer entered the year as a key bullpen piece, performance has a way of reshaping expectations, and the Braves may be forced to designate him for assignment to clear a spot.

The Braves have other options, of course. Veteran Carlos Carrasco, with his rubber arm, could provide depth on the upcoming road trip. And young J.R. Ritchie, who impressed in his last start, might be sent down if the team needs another bullpen arm. But much will hinge on Monday’s game against the Rockies. If Ritchie delivers again and Carrasco isn’t needed, Bummer could be the odd man out.

For a team with World Series aspirations, these decisions are never easy. But in the high-stakes world of MLB roster management, sometimes the toughest calls are the ones that keep a team in contention. Braves fans will be watching closely as Tuesday’s deadline approaches.
