San Diego Padres reliever Mason Miller has pitched 25 2/3 consecutive scoreless innings, the longest active streak in Major League Baseball. He stands just eight innings from tying the franchise record. Opposing hitters have struggled immensely against him during this dominant run.
Mason Miller has not allowed a run since August 5, 2025, his second appearance with the Padres following a trade deadline deal from the Oakland Athletics. This marks the eighth-longest scoreless streak in Padres history, trailing the franchise record of 33 2/3 innings set by Cla Meredith in 2006. Including the 2025 postseason and the 2026 World Baseball Classic, Miller's scoreless total reaches 32 1/3 innings. His 0.65 ERA ranks as the third-lowest through a pitcher's first 26 appearances with the Padres, behind Fernando Rodney's 0.34 in 2016 and John Urrea's 0.52 in 1981. This season, Miller has faced 15 batters, striking out 11, including nine straight swinging strikeouts dating to April 1, with only six called balls in those at-bats. His slider has proven particularly unhittable, generating a 76.9% whiff rate and 33 strikeouts in 44 plate appearances ending on the pitch during the streak. Opponents have managed just five singles in 79 at-bats against Miller, posting a .063 batting average and nearly 60% strikeout rate. The hitters who succeeded were Masataka Yoshida on August 9, 2025; Heliot Ramos on August 18; Josh Naylor on August 26; Warming Bernabel on September 6; and Luis Arraez on April 1, 2026. Arraez remains the only regular-season batter to get a hit among Miller's last 50 faced. Among 365 pitchers facing at least 75 batters since the streak began, Miller leads in opponents' batting average (.063), slugging percentage (.063), strikeout rate (59.6%) and whiff rate (52.2%).
