Major League Baseball teams increased active rosters from 26 to 28 players on September 1, utilizing the annual late-season expansion window. Clubs are integrating various prospects and returning veterans as the regular season enters its final month. San Diego Padres catcher Ethan Salas, 20, joined the major-league roster to support a wild-card push, while the Los Angeles Dodgers activated Will Smith following his recovery from neck inflammation. In Seattle, 21-year-old outfielder Lazaro Montes made his debut, recording his first career home run against the Boston Red Sox. While rosters are smaller than in previous years due to current regulations, the addition of two players per team provides depth for postseason contenders and evaluation opportunities for rebuilding organizations.
