Duran’s 13th homer erased a two-run deficit in the fifth inning and propelled the second-place Red Sox to their fourth win in five games.
Sugano (10-6) gave up four runs and six hits in six innings to absorb his first loss in eight starts since July 2. Six days earlier, the 35-year-old rookie from Japan held Boston without an earned run over five innings in a Baltimore victory.
After Anthony hit the first leadoff homer of his career, Baltimore’s Colton Cowser smacked a solo homer in the second inning and added a two-run single in the third.
Duran connected after singles by Connor Wong and Anthony, and the one-run lead held up.
Boston’s Richard Fitts (2-4) gave up three runs in four innings before leaving with right biceps tightness.
Garrett Whitlock struck out the side in the eighth after Gunnar Henderson hit a leadoff double, and Aroldis Chapman worked a perfect ninth for his 25th save in 27 tries.
Chapman has not allowed a hit in his last 13 appearances, the longest streak in Red Sox history.
In the seventh inning, Baltimore’s Dylan Carlson was called safe at third on a sacrifice bunt by Luis Vázquez. But after a Boston challenge, the call was overturned. Jackson Holliday followed with a deep flyball that would have easily got Carlson home.
Duran has reached base in 19 straight games, tying his career high. It’s the longest current streak in the majors.
Kyle Bradish makes his first start for Baltimore since June 2024, returning from Tommy John surgery to face the Red Sox and Lucas Giolito (8-2, 3.72 ERA) on Tuesday night.
