As Week 5 of the fantasy baseball season approaches, players like Nick Kurtz, Adael Amador, and Lance McCullers Jr. are generating buzz on the waiver wire. Kurtz, the Athletics' first baseman, is attracting attention after an impressive debut. However, potential investors should temper expectations due to the typical struggles rookies face when adjusting to MLB pitching. Meanwhile, Amador, who recently debuted with the Rockies, has shown promise but comes with risks, especially regarding playing time in a volatile Rockies lineup.

McCullers Jr. is making a comeback for the Astros after injury but has exhibited concerning walk rates in rehab. Despite his previous success, fantasy managers should approach with caution, as he may not regain his prior form immediately. Knowing when to bid on these players could be crucial in securing a competitive edge.

The Washington Nationals are gearing up for a new season with a blend of young talent and veteran acquisitions, aiming to build a stronger roster compared to last year. Despite a D+ offseason grade from ESPN's David Schoenfield, the team made strategic moves by signing Nathaniel Lowe, Josh Bell, Paul DeJong, and Amed Rosario, who are expected to enhance their power-hitting capability. Additionally, the team retained Trevor Williams and added Michael Soroka and Shinnosuke Ogasawara to bolster their pitching staff.

While the Nationals are not expected to challenge for a playoff spot this year, they have set themselves up for future success by allowing their younger players to develop. The aim is to avoid rushing into free-agent signings that could derail the rebuilding process. This cautious approach is aimed at evaluating the performance of their prospects while ensuring they do not lose significant players in the process.
