Phillies Expected to Pursue Athletics Reliever Mason Miller at 2025 Trade Deadline

The Philadelphia Phillies have bolstered their bullpen by signing veteran reliever David Robertson and are actively pursuing additional reinforcements ahead of the MLB trade deadline. A primary target is Oakland Athletics' closer Mason Miller, who was once considered untouchable but may now be available as the Athletics struggle this season. Multiple reports identify the Phillies as the top contender to acquire Miller, despite stiff competition from the Los Angeles Dodgers and New York Yankees, with the Athletics expected to demand a significant package of top prospects in return. The Phillies also seek to strengthen their offense, showing interest in players like Boston's Jarren Duran and others to improve lineup depth and versatility. The front office, led by President of Baseball Operations Dave Dombrowski, appears willing to make bold moves to address bullpen weaknesses and capitalize on the team's championship window. However, acquiring Miller would require a substantial trade, likely involving several highly-ranked prospects, underscoring the high stakes for Philadelphia as the July 31 deadline approaches.
