The third base position is heating up with an influx of exciting prospects ready to make their mark in 2025. With a mix of established talent and rookies set to debut, fantasy owners should prioritize these players for significant contributions. The position boasts elite options, but also several promising newcomers who could provide immense value. Watch for players like Cam Smith of the Houston Astros, whose rapid ascent has him starting the season on the MLB roster after an impressive spring training performance. Meanwhile, Matt Shaw of the Chicago Cubs has shown potential despite a rough spring, and Coby Mayo of the Baltimore Orioles remains a must-watch as he navigates minor league play. Jace Jung (Detroit Tigers) and Brady House (Washington Nationals) are also on the radar for future call-ups. Stashing these players could offer immense upside as they transition to full-time roles.
