As the calendar approaches June, the trade rumor season in Major League Baseball (MLB) begins to gain momentum. With Memorial Day soon upon us, various storylines are emerging ahead of the July 31 trade deadline. This article introduces a BS Meter with four settings—non-existent, low, medium, and high—to help fans gauge the credibility of trade rumors, rather than question the integrity of the reporters involved.

One notable rumor comes from MLB.com's Mark Feinsand, who reported that the Philadelphia Phillies reached out to veteran pitcher David Robertson prior to the public revelation of José Alvarado's 80-game suspension for a performance-enhancing drug violation. Feinsand emphasized that no serious negotiations occurred. This rumor receives a 'low' rating on the BS Meter as the discussion about acquiring more bullpen support for the Phillies was warranted, especially after losing Alvarado, a key player in their bullpen. However, the lack of serious negotiations and the fact that Robertson, despite a strong 2023 season, remains a free agent raises questions about his current status and whether he is seeking a specific contract arrangement or contemplating retirement. It remains uncertain if he will ultimately sign with the Phillies or another team before the season progresses.

Another significant trade rumor reported by Bob Nightengale of USA Today indicates that the Los Angeles Dodgers and Chicago Cubs are closely monitoring Colorado Rockies infielder Ryan McMahon in the event that the Rockies opt to trade him. The BS Meter rates this rumor as 'high,' given the Rockies' traditionally cautious approach to being major sellers during the season, even amidst poor performance. With McMahon currently struggling offensively—hitting .211 with a .706 OPS—his trade value is in question. Additionally, McMahon's financial commitments over the next few years complicate the situation. The Rockies could consider eating some of his salary or accepting a lesser prospect in return to facilitate a trade, but the likelihood of this happening is uncertain, especially if the Dodgers do not see a fit unless they doubt Max Muncy's ability to bounce back.

Jon Heyman recently asserted that there is 'no way, no how, no chance' that the Pittsburgh Pirates will trade pitching prospect Paul Skenes this summer. This analysis is rated as 'non-existent' on the BS Meter. While contending teams have expressed interest in Skenes, the 22-year-old pitcher, who boasts a 2.12 ERA in his first 33 MLB starts, represents a foundational piece for the Pirates' future. Given the long-term control available under his contract, it would be imprudent for the Pirates to trade such a promising talent, especially with the team's current struggles. Skenes is expected to be a crucial element in the Pirates' attempt to build a competitive roster moving forward.

In another opinion piece, Nightengale suggested that Rhys Hoskins could be an ideal fit for the Boston Red Sox should the Milwaukee Brewers decide to sell. This assessment received a 'low' rating on the BS Meter, as it reflects speculation rather than hard reporting. The potential interest from the Red Sox in Hoskins makes sense due to his power-hitting capabilities, particularly at Fenway Park. However, the Brewers remain a fringe contender in the National League, and it's unclear whether they will choose to trade Hoskins, especially considering their recent history of dealing veterans. Hoskins is experiencing a resurgence this season with a .902 OPS after recovering from a torn ACL, and it is likely he will decline his option for the 2026 season, which could make him an attractive trade asset should the Brewers consider a sale.

Finally, in his latest commentary, Jon Heyman commented that Luis Robert Jr. is unlikely to be traded if he continues to perform poorly, particularly if he is hitting below .200. This statement is rated as 'non-existent' on the BS Meter. Robert's current contract, which is perceived as a value for his potential, places him in a position where teams would hesitate to invest heavily unless he demonstrates improvement. Despite his struggles, Robert remains an intriguing player with base-stealing speed and defensive prowess. However, the long-term nature of his contract and the uncertainty surrounding his performance may deter teams from making serious trade offers for him at this time.
