Mason Miller
#22 Active2026 Fantasy Baseball Player Profile
Mason Miller’s 2025 season was a masterclass in pure, unadulterated dominance that reached its peak after a mid-season blockbuster trade. Split between the Athletics and the Padres, Miller finished the regular season with a 2.63 ERA, 0.91 WHIP, and 22 saves (20 with Oakland, 2 with San Diego). While he had a brief, shaky stretch in May, he became a literal "cheat code" upon arriving in San Diego. In his 23.1 innings as a Padre, Miller posted a microscopic 0.77 ERA and struck out 45 of the 83 batters he faced—a staggering 54.2% strikeout rate. He punctuated his year by tying a postseason record with eight consecutive strikeouts during the Padres' Wild Card series against the Cubs.
The 2026 season brings the clarity fantasy managers and Padres fans have been craving. Despite persistent offseason rumors that San Diego might convert him back into a starting pitcher, manager Craig Stammen officially confirmed in February that Miller will remain the team’s primary closer. With veteran Robert Suarez departing for Atlanta in free agency, the ninth inning belongs entirely to the 27-year-old fireballer. Miller has publicly embraced the role, noting that anchored in the bullpen is where he has had his greatest success and where he can best help the team's current goals.
For fantasy managers, Miller has ascended to a true "RP1 anchor" with an ADP around 27.

AVG, OBP, SLG, ERA and WHIP are season-to-date through each game, not that game alone — so the column reads as a trend and its last value is the season figure. They stay season-to-date when the log is filtered by opponent; the figure for the filtered games is the one in the Total row. The second game of a doubleheader is marked (2).
