In Week 4 of the 2025 fantasy baseball season, several hitters are primed for waiver wire consideration. Rhys Hoskins of the Milwaukee Brewers stands out with a 23% K-rate and a solid performance against right-handed pitchers, making him a valuable first base option. Gavin Sheets of the San Diego Padres has been crushing righties and is expected to continue his hot streak with favorable matchups. Tyler Fitzgerald is emerging as a must-add second baseman for the San Francisco Giants, while Jorge Polanco and Jonathan India offer steady contributions at second and third base, respectively.

Outfielders TJ Friedl and Sal Frelick are also on the radar, with Friedl benefitting from Coors Field's hitter-friendly environment. Catcher Hunter Goodman is another name to watch, especially with good matchups against left-handed pitchers. As injuries continue to plague the league, these players present opportunities to improve your roster and capitalize on favorable matchups this week.
