As the Major League Baseball (MLB) trade rumor season approaches its peak, conversations are beginning to emerge surrounding potential moves ahead of the July 31 trade deadline. With Memorial Day nearing, several storylines are starting to take shape in the lead-up to a crucial period for teams. This article presents a BS Meter with four levels—non-existent, low, medium, and high—to gauge the credibility of the reported rumors circulating in the league. The intent of this meter is not to undermine the professionalism of the reported sources, but rather to inform fans about the likelihood of these insights leading to actual transactions.

In a recent report by MLB.com's Mark Feinsand, it was indicated that the Philadelphia Phillies had "reached out" to veteran reliever David Robertson prior to José Alvarado’s suspension for performance-enhancing drugs becoming public knowledge. Notably, Feinsand mentioned that "no serious talks took place". This report scores a low on the BS Meter, reflecting a reasonable degree of credibility. Prior to Alvarado's suspension, the Phillies appeared to require bullpen reinforcements, and Robertson, who is currently a free agent, represents a logical option. However, the lack of progression in talks and Robertson's continued status as a free agent raises questions. At 40 years of age, it is uncertain why he has not yet signed with a team, despite his successful last season where he posted a 3.00 ERA and 2.65 FIP for the Texas Rangers. Questions arise regarding his contract expectations or his desire to continue his career. While it is likely that Robertson will find a team eventually, it may take time for him to be prepared for MLB action, whether that ends up being with the Phillies or another club.

Another rumor reported by Bob Nightengale of USA Today suggests that the Los Angeles Dodgers and the Chicago Cubs are "closely monitoring" Rockies infielder Ryan McMahon, should Colorado decide to trade him. This rumor is rated high on the BS Meter due to the Rockies' historically poor performance and their pattern of avoiding significant midseason trades. Despite the team's struggles, owner Dick Monfort and general manager Bill Schmidt may still hesitate to part with a key player like McMahon, who is currently hitting .211 with a .706 OPS. His defensive skills remain impressive, but potential trade partners might be wary of his batting performance. Adding to the complexities, McMahon is owed $32 million between 2026 and 2027, which may limit the Rockies' options for trading him unless they are willing to take on some salary or accept a lesser return.

In discussing the Pittsburgh Pirates, Jon Heyman commented on the improbability of the team trading young pitcher Paul Skenes this summer, declaring, "No way, no how, no chance". This statement registers as non-existent on the BS Meter. Despite speculative narratives from fans of contending teams wishing to see Skenes dealt, he represents a foundational player for the Pirates moving forward. At just 22 years of age, Skenes has demonstrated significant potential with a 2.12 ERA in his first 33 MLB starts. The idea of trading such a talent early in his career is dismissed as impractical, particularly given the team’s recent struggles. While it is conceivable that the Pirates might consider trading him when he nears free agency, that scenario appears distant at this point.

Lastly, Nightengale ventured the opinion that Rhys Hoskins would be an ideal fit for the Boston Red Sox if the Milwaukee Brewers decide to become sellers this season. This assessment receives a low rating on the BS Meter as it remains an opinion rather than a solid report. Nonetheless, Hoskins' power-hitting capabilities align well with Fenway Park's favorable hitting conditions. However, the Brewers, currently at 24-26, are still in contention and may be hesitant to part with a player who has exhibited a resurgence after struggling post-injury. Hoskins has shown improvement with a .902 OPS this season, raising considerations about his future contract situation. Should the Brewers choose to trade Hoskins, they may see him as an opportunity to secure prospects while mitigating obligations regarding his contract buyout. Notably, Hoskins has a strong reputation within baseball and could attract attention from the Red Sox as well as other teams in need of offensive support.

In other reports, Heyman pointed out that a trade involving Luis Robert Jr. is unlikely if his performance remains below .200, stating that he would not fetch a favorable return under such circumstances. This assessment scores non-existent on the BS Meter. Robert, who was previously considered to have a team-friendly contract, is currently struggling with a .210 batting average and has been plagued by injuries. Though he retains value with his speed and defensive skills, teams may view him more as a rental option rather than a long-term investment. Given the uncertainties surrounding his fitness and performance, teams may be hesitant to offer top-tier prospects for his services unless a significant improvement is noted.
