The Cincinnati Reds placed closer Emilio Pagan on the injured list Wednesday following a Grade 2 left hamstring strain [1].

The loss of the 34-year-old [4] reliever leaves a gap in the Reds' late-inning bullpen during a critical stretch of the early season. To address the vacancy, the team promoted reliever Tejay Antone from Triple-A Louisville to the major-league roster [1].

Pagan suffered the injury Tuesday night [3]. The pitcher said that his hamstring was not 100 percent before the game on Tuesday.

“The Grade 2 diagnosis carries with it a four-to-eight week timetable,” Pagan said [1]. He said that the four-to-eight week timeline is actually a positive outcome [2].

Manager Terry Francona said that the move to bring up Antone was a direct response to the injury. “We’ll bring Tejay Antone up; he’s ready to contribute at the big-league level,” Francona said [2].

Antone joins the active roster as the team seeks to stabilize its pitching rotation while Pagan undergoes rehabilitation. The Grade 2 strain is a significant injury that typically requires several weeks of physical therapy, and gradual return-to-play protocols, before a pitcher can return to maximum effort on the mound [1].

The Reds' front office now faces the challenge of managing the bullpen workload without their primary closer for at least a month. The team will rely on Antone and other available relief arms to maintain their lead in the final frames of games until Pagan is cleared for a return [1].

“The Grade 2 diagnosis carries with it a four-to-eight week timetable.”

The loss of a primary closer for up to two months forces Cincinnati to rely on unproven depth or a committee approach in high-leverage situations. While Tejay Antone provides an immediate replacement, the stability of the bullpen is compromised until Pagan returns, potentially increasing the workload and fatigue of other relief pitchers.
