The 2025 fantasy baseball season is heating up, and Week 2 provides numerous category boosters available on the waiver wire. Key players like Jung Hoo Lee from the Giants are making contributions in runs scored, hitting .300 with 10 runs and 3 stolen bases, while Kyren Paris of the Angels is a rising star with 10 runs in the last two weeks. For home runs, Yankees' Ben Rice and Trent Grisham are prominent additions, both taking advantage of their opportunities in high-powered lineups. In terms of RBIs, Kyle Manzardo continues to drive in runs effectively, despite a lower batting average, while Geraldo Perdomo shows promise in the Diamondbacks' lineup. Stolen base candidates include Zac Veen, who brings speed from the Rockies, and Dylan Moore, who has shown his ability to produce both power and speed in the Mariners lineup. Lastly, for batting average, Jacob Wilson and Jorge Polanco are must-adds for managers needing an average boost.
