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.
