The San Diego Padres are considering significant player moves, including the potential trade of star closer Mason Miller and key pitcher Michael King, as the Aug. 3 MLB trade deadline approaches. President of Baseball Operations A.J. Preller is weighing whether the team will be a buyer or seller, with the decision hinging on the club's performance over the next two weeks. As of Friday, the Padres trailed the final National League wild-card spot by 3 1/2 games.
If San Diego opts to sell, "multiple sources" indicate that the team is open to trading several prominent players. This list includes the highly effective closer Mason Miller, acquired from the Athletics last summer in a deadline deal orchestrated by Preller. The Padres also have not ruled out trading high-leverage lefty Adrian Morejón or right-handed pitcher Michael King.
King, who joined the Padres in the 2023 trade that sent Juan Soto to the Yankees, has posted a 3.41 ERA with 92 strikeouts over 108.1 innings this season, holding a 6-7 record. His performance is similar to his 2025 season, which was impacted by injuries.
Morejón, signed as an international free agent from Cuba, has recorded a 3.42 ERA this year, a notable increase from his 2.08 ERA in 2025.
The potential departure of Miller, described as baseball's best closer, would be a significant loss for the Padres. However, the team has experienced a difficult season, prompting considerations for drastic changes. Preller has a history of making unexpected moves, suggesting that any decisions leading up to the deadline could be surprising.
