Scouting Report: Mason Miller

Summary

Mason Miller, the San Diego Padres' closer, is having an exceptional 2026 season with elite performance metrics. He posted a 34.2-inning scoreless streak dating back to last season and currently has an ERA of 0.96 with 38 strikeouts in 18.2 innings. His batting average allowed sits at .121, on pace to challenge the all-time record of .113. Miller throws 101 mph fastballs and is on pace for approximately 421 pitches of 100+ mph. However, he has shown some inconsistency this season, particularly with control issues (two walks in a recent save). He recently allowed two runs against the Cubs in what was largely attributed to soft contact. Miller is planning to adjust his pitch mix by using his fastball more frequently (currently using slider 51.5% of the time) to further elevate his game. The Padres have managed to go 27-18 and lead the majors with 39 runs scored in the ninth inning or later, with Miller largely responsible for this success.
