As Memorial Day approaches, Major League Baseball's trade rumor season begins to take shape ahead of the July 31 trade deadline. While serious discussions typically heat up in June, preliminary storylines are emerging that may significantly impact team strategies for the summer. Moneyline presents a BS Meter designed to gauge the credibility of various rumors without questioning the integrity of the sources involved, allowing fans to understand the likelihood of these insights leading to actual moves.

One noteworthy rumor involves the Philadelphia Phillies, as reported by MLB.com's Mark Feinsand. According to Feinsand, the Phillies initiated contact with veteran pitcher David Robertson prior to the announcement of José Alvarado's subsequent 80-game suspension for performance-enhancing drugs. However, it was emphasized that no significant negotiations had transpired. The BS Meter rates this rumor as 'Low,' suggesting that while the report is credible, the actual chances of a deal materializing appear minimal. The Phillies, facing a need for bullpen assistance following Alvarado's suspension, rightfully considered Robertson, a self-represented free agent. Nevertheless, concerns linger regarding Robertson's prolonged absence from a roster despite a successful 2023 season, raising questions about his demands and future intentions. It is expected that the seasoned pitcher may eventually return to play, though his timeline remains unclear, amplifying speculation about his next destination.

In an interesting development, Bob Nightengale of USA Today reported last weekend that both the Los Angeles Dodgers and Chicago Cubs are carefully monitoring Ryan McMahon, anticipating potential trade discussions involving the Colorado Rockies third baseman. The BS Meter places this rumor in the 'High' category, reflecting considerable interest. The Rockies have historically been reluctant to sell major assets mid-season, even amid poor performance. The fate of McMahon's availability hinges on Rockies management's willingness to pivot from their current strategy, especially given his subpar batting metrics this season. Although McMahon still boasts strong defensive capabilities, concerns about his value as a trade asset are warranted due to his performance and salary commitments. The Dodgers may not represent the most logical destination, unless they foresee an ongoing struggle with Max Muncy's offensive contributions.

Another rumor discussed by Jon Heyman in a recent appearance on B/R suggests that Paul Skenes of the Pittsburgh Pirates is not on the trading block this season. The BS Meter designates this statement as 'Non-existent,' reflecting overwhelming consensus. Despite the challenging circumstances surrounding the Pirates' season, the idea of trading a young talent like Skenes, who has established a strong track record in his early career, is ill-conceived. Skenes remains under club control until at least the 2029 season, leading many to believe he embodies a cornerstone for the franchise moving forward. While discussions regarding Skenes may arise prior to his impending free agency, such speculation is premature. The Pirates should focus on fostering talent like Skenes for future success.

Additionally, Nightengale suggested that the Boston Red Sox might find Rhys Hoskins to be an ideal acquisition if the Milwaukee Brewers opt for a trade. rated as 'Low' on the BS Meter, this speculation arises more from opinion than any concrete reporting. Given Hoskins' power-hitting profile and the advantageous hitting conditions at Fenway Park, such a partnership seems plausible. However, the Brewers' current standing within the playoff race raises doubts as to whether they would consider selling. Although Hoskins is experiencing a rebound in performance, the decision to trade him would hinge on the Brewers' willingness to accept a prospect return while potentially shedding financial obligations linked to his contract.

Lastly, Jon Heyman again remarked on Luis Robert Jr.'s potential trade value, indicating that the likelihood of a trade is highly contingent on his current performance. This statement is marked as 'Non-existent' on the BS Meter, highlighting clear logic. While once considered a promising talent due to his prior contract structure and performance, his recent struggles have clouded opinions regarding his worth on the market. Potential trade suitors may perceive Robert as a rental given his escalation in salary, which further complicates any potential return on investment. The combination of injury history and lackluster hitting presents frontline challenges recruiters might face when deliberating on a transaction involving the skilled player.
