Diamondbacks Extend Martinez Pending Physical

The Arizona Diamondbacks have agreed to a five-year, $18 million contract extension with 23-year-old reliever Justin Martinez, pending a physical. The deal covers his arbitration-eligible years and includes club options for 2030 and 2031, valued at $7 million and $9 million, respectively. Martinez, known for his dominant triple-digit fastball, posted a 2.48 ERA with 91 strikeouts over 72 2/3 innings in his first full MLB season in 2024. Despite some command issues, he is considered a potential closer for the Diamondbacks due to his impressive performance and strikeout rate. The extension offers Martinez financial security while providing the team with a cost-effective solution for their bullpen. Sources suggest he will likely get numerous save opportunities and could become the team's primary closer if he continues to perform well.
