Red Sox Call Up Paez for Debut Amid Roster Expansion

The Boston Red Sox expanded their roster to 28 players on September 1, 2026, adding right-handed pitcher Jedixson Paez and infielder Isiah Kiner-Falefa. Paez, a 22-year-old prospect, was scheduled to make his first major league start against the Seattle Mariners, while Kiner-Falefa returned from a six-month injury absence. The moves coincided with the placement of Eduardo Rivera on the injured list and the designation of Brett Harris for assignment.
Key points
- Jedixson Paez was added to the major league roster from Triple-A Worcester and was slated to start against the Seattle Mariners on Tuesday.
- Isiah Kiner-Falefa was reinstated from the 60-day injured list after recovering from a right forearm stress reaction that sidelined him since mid-June.
- The Red Sox placed Eduardo Rivera on the 60-day injured list due to a lumbar strain and designated Brett Harris for assignment to make room for the new additions.
- Paez had previously been selected by the Chicago White Sox in the Rule 5 Draft but was returned to Boston, where he pitched to a 4.11 ERA in 20 minor league appearances.
- Kiner-Falefa was hitting .277 with two home runs in 47 games before his injury, providing defensive depth for the Red Sox infield.
Background
This roster expansion marks the start of September, a period when MLB teams typically expand their rosters to 28 players to manage fatigue and injuries during the final stretch of the regular season. Recent archive coverage from late August highlighted the importance of pitching depth and health, noting that pitchers like Chris Sale and Andrew Painter were delivering high-quality starts, while others faced command or injury issues. The addition of Paez and Kiner-Falefa reflects the Red Sox's strategy to bolster their rotation and infield defense as they navigate the final month of the season.
How outlets are covering it
Pitcher List focused on the fantasy implications of Paez's debut, analyzing his pitch mix and command issues in his first major league start, where he struggled with 3.2 innings, 8 earned runs, and 10 hits. The outlet noted that while his minor league numbers were impressive, his major league debut was rough, and he was subsequently returned to the minors. 98.5 The Sports Hub provided a broader organizational perspective, detailing the specific roster moves, including the reinstatement of Kiner-Falefa and the placement of Rivera and Harris, emphasizing the team's need for depth and defensive stability as the season progresses. The two outlets differed in focus, with Pitcher List concentrating on performance metrics and fantasy value, while 98.5 The Sports Hub highlighted the logistical and strategic aspects of the roster changes.
Why it matters
The addition of Paez and Kiner-Falefa signals the Red Sox's intent to maximize their roster depth and defensive capabilities in the final month of the regular season. Paez's debut, despite a rough performance, provides a glimpse into the team's future pitching options, while Kiner-Falefa's return addresses a significant gap in the infield. These moves are crucial for the Red Sox as they aim to maintain competitiveness and manage player fatigue, potentially influencing their playoff positioning and long-term roster planning.
What to watch
The Red Sox will monitor Paez's performance in the minors to determine if he warrants another major league call-up in September. Kiner-Falefa's return will be evaluated for his impact on the infield defense and overall team chemistry. The team will also assess the health and performance of Eduardo Rivera and other key players as they navigate the final stretch of the season. Fantasy managers will watch Paez's minor league outings for signs of improved command and strikeout potential, while the Red Sox will continue to manage their roster to optimize performance and player health.
