As fantasy baseball managers navigate the waiver wire in Week 10, several undervalued players have emerged as potential game-changers. Rhys Hoskins of the Milwaukee Brewers, with 47% rostered, has been a consistent performer, hitting .264 with nine homers and 35 RBIs while providing utility at first base. Jose Caballero from the Tampa Bay Rays, positioned as a leadoff hitter, is on track for over 50 steals this season and should be on every roster. Also on the rise is Brewers outfielder Sal Frelick, boasting a .393 batting average over the last week, with impressive speed and power metrics that make him a solid addition. Lourdes Gurriel Jr., quietly effective for the Arizona Diamondbacks, continues to deliver steady production, while Ryan O'Hearn of the Baltimore Orioles has become a reliable contributor amidst the team's injury struggles.
