Spring Training has kicked off for the Arizona Diamondbacks at Salt River Fields, where promising right-hander Justin Martinez is looking to build on a strong 2024 season. At just 23 years old, Martinez achieved a standout performance with a 2.48 ERA and 2.59 FIP over 72.2 innings, primarily in high-leverage situations, even stepping into the closer role briefly. He successfully converted 8 of 10 save opportunities, showcasing his potential as a reliable reliever.

Martinez expressed that last season provided invaluable experience, preparing him for the rigors of pitching under pressure. With a focus on hard work and continuous improvement, he remains unperturbed by the competition for the closer role with other candidates like A.J. Puk and Kevin Ginkel. His commitment to readiness and physical strength has him excited about the potential for success this season, regardless of his specific role in the bullpen.

As the MLB off-season unfolds, projections from ZiPS and Steamer are being analyzed at Arizona Diamondbacks On SI, focusing on the performance expectations for each member of the team. The site aims to provide a comprehensive overview of players by averaging projections and assessing individual contributions based on rate statistics and playing time.

The evaluation extends beyond the 26-man roster typically utilized on Opening Day, encompassing the entire 40-man roster and including promising minor-leaguers and prospects that may impact the Diamondbacks' 162-game season.

The Philadelphia Phillies are navigating a quiet offseason, reflecting on a disappointing playoff exit last year. With high hopes heading into the postseason, the Phillies fell short, winning only one game against the New York Mets in the NLDS. Major issues, particularly in the outfield and a struggling bullpen, were significant factors in their early exit from the playoffs. Although changes have been limited, the organization did make an important addition to their bullpen by signing Jordan Romano from the Toronto Blue Jays.

While the Phillies faced free agency losses with two relief pitchers, they have made moves to revamp their bullpen without a significant overhaul of their outfield. With Jeff Hoffman reportedly signing with the Blue Jays, there remains interest in Carlos Estevez, who is still available in the free agency market. Estevez has been identified as a strategic fit for the Arizona Diamondbacks, who are also looking to bolster their bullpen. The Diamondbacks recently signed Corbin Burnes, indicating their ambitions for the upcoming season.

Despite the changes, the Phillies should consider retaining Estevez to strengthen their bullpen. With Romano as the new closer, the Phillies will rely on Orion Kerkering in high-leverage situations, an important yet challenging role for a young player. The franchise aims to compete effectively in the National League, making the retention of Estevez a worthwhile consideration as they look to enhance their competitive edge.

The Arizona Diamondbacks are well-equipped with starting pitchers as they approach the 2025 season, which may lead to innovative strategies for utilizing their depth. With five established starters and promising prospects, the team faces a decision regarding Drey Jameson, who is recovering from Tommy John surgery.

Jameson, expected to return by Spring Training, may transition to a relief role instead of starting, given his extended absence from competitive play. The Diamondbacks have already experimented with him in the bullpen, and his previous performances suggest he could adapt well to this new position.

Devin Williams, the Milwaukee Brewers' All-Star closer, is now a trade candidate after the team declined his $10.5 million option for 2025. With a solid track record and a projected arbitration salary of $8-9 million, Williams is expected to bring substantial value in a trade.

Several teams, including the San Diego Padres, Los Angeles Dodgers, and New York Yankees, are potential landing spots for the talented right-hander. The Brewers are likely to seek a mix of prospects and established players in return, as they prepare for a competitive 2025 season.
