As Memorial Day approaches, Major League Baseball (MLB) trade rumor season begins to take shape, offering insights into potential moves ahead of the July 31 trade deadline. To aid in analyzing these rumors, a BS Meter has been created with four levels: non-existent, low, medium, and high. The purpose of this meter is not to question the credibility of the reporters but to provide fans with an understanding of the likelihood that these insights will lead to actual trades.

One significant rumor involves the Philadelphia Phillies, as reported by Mark Feinsand of MLB.com. It was noted that the Phillies had 'reached out' to relief pitcher David Robertson prior to the announcement of José Alvarado’s 80-game performance-enhancing drug suspension. While this interaction did not lead to serious discussions, the Phillies' need for bullpen assistance has only increased following Alvarado's suspension. Although Robertson, a 40-year-old veteran who previously recorded a 3.00 ERA and 2.65 FIP in 68 games for the Texas Rangers, remains a free agent, there are uncertainties regarding his market appeal at this stage of the season. Potential questions regarding his contract demands or personal considerations could be delaying his signing, but it is likely that he will find a team eventually, even if it takes some time before he can contribute on the field.

Another rumor surfaced from Bob Nightengale of USA Today indicating that the Los Angeles Dodgers and Chicago Cubs are 'closely monitoring' Ryan McMahon of the Colorado Rockies, should the Rockies choose to trade him. The organizational approach of the Rockies has typically been one of reluctance to sell major assets, and even amidst struggles this season, it is uncertain if the team will alter its course. McMahon, who has struggled offensively this season with a .211 batting average and a .706 OPS, still possesses strong defensive capabilities at third base. However, with his upcoming $32 million salary between 2026 and 2027, it raises questions about how interested other teams will be in acquiring him. The Dodgers' interest specifically is questionable unless they see a significant need to address third base, particularly concerning Max Muncy’s performance.

In an additional update, Jon Heyman of B/R recently stated that there is 'no way, no how, no chance' the Pittsburgh Pirates will trade Paul Skenes this summer. Despite growing speculation from fans of contending teams, the reality remains that Skenes, just 22 years old and not eligible for arbitration until 2027, represents a critical building block for the Pirates. With a stellar 2.12 ERA over his first 33 starts, he is deemed a 'generational talent' and a player the franchise should focus on developing rather than trading, even amid a challenging season.

Furthermore, there are opinions circulating about Rhys Hoskins potentially being a fit for the Boston Red Sox, as expressed by Nightengale. While this is not a direct report, the notion of a left-handed power hitter finding success at Fenway Park is a plausible scenario. Should the Milwaukee Brewers decide to trade Hoskins, who has shown a significant resurgence this season after recovering from a torn ACL, it could be an opportunity for teams seeking more offensive production from their first-base or designated hitter positions. However, whether the Brewers are in a position to sell remains to be seen, especially with their current standings close to contention.

Lastly, another observation from Heyman noted that Luis Robert Jr. is unlikely to be traded by the Chicago White Sox, particularly if his performance remains underwhelming. Robert's contract, previously viewed as team-friendly, is currently less favorable given that he is batting .210 this season. Despite his notable athleticism, including 17 stolen bases, potential trade interest may be limited unless he can significantly improve his production. As it stands, teams will likely approach him as a rental player, factoring in his substantial contract options and injury history.
