A.J. Preller Speaks on Mason Miller Trade Speculation

The San Diego Padres gave up a massive haul to acquire star closer Mason Miller at last year's trade deadline.

The 27-year-old, along with starter JP Sears, was acquired from the Athletics in exchange for four prospects, including shortstop Leo De Vries, MLB Pipeline's No. 3 overall prospect at the time (now No. 2).

Despite the hefty price, Miller was nearly unstoppable following the trade. In 22 appearances with the Padres in 2025, Miller posted a 0.77 ERA with 45 strikeouts and 10 walks over 23.1 innings. He surrendered just two earned runs, one home run, and held opposing hitters to a .096 batting average.

He has been just as dominant, if not better, in his first full season with San Diego. Across 37 appearances, Miller owns a 0.93 ERA with 71 strikeouts and 13 walks. He has allowed just four earned runs over 38.2 innings and has yet to surrender a home run.

More impressively, Miller is a perfect 24-for-24 in save opportunities. His 24 saves are tied for the National League lead and rank among the top five in MLB.

Despite Miller's stellar season, however, the Padres' 2026 campaign has fallen short of expectations. Entering the final day before the All-Star break, San Diego owns a 47-48 record. The club sits 13.5 games behind the National League West-leading Los Angeles Dodgers and 4.5 games out of the final National League Wild Card spot.

The Padres' disappointing season has fueled speculation that the club, which is typically one of baseball's most aggressive buyers at the trade deadline, could instead become a seller. If San Diego makes players available, Miller would immediately become one of the most coveted trade pieces on the market.

Preller Shuts Down Miller Rumors

On Saturday, Padres president of baseball operations A.J. Preller reaffirmed the organization's long-term commitment to Miller.

“Since we made the deal last year, he’s performed as good as you could want somebody to perform," Preller said. "We made the deal with the intention that Mason is going to be here for a long time. He’s done an unbelievable job. And our intent is still the same as when we made the deal last year.”

Moving one of the best closers in baseball just one year after giving up an enormous package would run counter to the aggressive approach the Padres have taken in recent seasons.

San Diego acquired Miller with the expectation that he would lock down the ninth inning for years to come. He has done exactly that during his brief tenure with the Padres and remains under team control through the 2029 season.

Any trade involving Miller would undoubtedly require a significant return. However, the Padres are not completely out of postseason contention, sitting just 4.5 games behind the Miami Marlins for the third and final National League Wild Card berth.

According to MLB executives, San Diego is still viewed as more likely to be a buyer unless the club falls further out of the Wild Card race as the trade deadline approaches.

Preller is no stranger to making blockbuster moves. In 2022, the Padres acquired both closer Josh Hader and outfielder Juan Soto. Last year, he once again shook up the baseball landscape by trading for Miller.

Given Preller's track record and all-in reputation, dealing Miller would go against the organization's recent philosophy. Nevertheless, the All-Star closer will remain one of the most compelling names to watch ahead of the Aug. 3 trade deadline.
