Fourth-out rule sparks intrigue as Rutschman nears return, Kremer shines, Senga seals Mets save

The Opener recaps a rare fourth-out ruling in the Red Sox–Blue Jays game that allowed a run to score before an appeal would nullify it, notes Adley Rutschman is set to rejoin the Red Sox after wrist inflammation, highlights Dean Kremer’s seven-inning, one-run gem against his former Orioles for Minnesota, and reports Kodai Senga’s first save for the Mets after Devin Williams went on the injured list, with a potential continued closer role if his stuff remains dominant.
