As the fantasy baseball season hits Week 19, managers face tough decisions regarding underperforming players. A mix of established stars and emerging talents, players like Kodai Senga and Paul Goldschmidt have stirred concern among their fantasy owners. Senga, previously a standout for the New York Mets, is struggling post-injury with a concerning ERA and control issues. Meanwhile, Goldschmidt's recent slump leaves many questioning if it's time to part ways. On the other hand, Jake Mangum and James Wood present opportunities for savvy managers to buy low as they navigate through their struggles while still holding potential upside.

Fantasy managers must evaluate whether to hold, drop, or sell low on these players as the playoffs approach. With the season reaching its critical phase, making informed moves can determine league outcomes. Senga and Wood's talent suggests patience may pay off, while Goldschmidt's decline indicates it might be time to cut losses.
