As Memorial Day approaches, the MLB trade rumor season begins to take shape, giving fans a glimpse into the key storylines leading up to the July 31 trade deadline. With this in mind, the following assessments provide insight into various rumors surrounding significant players and their potential moves, using a BS Meter that categorizes the credibility of each report.

One notable rumor involves the Philadelphia Phillies, as reported by Mark Feinsand of MLB.com, who stated that the Phillies reached out to veteran pitcher David Robertson before the announcement of José Alvarado’s suspension for performance-enhancing drugs. While Feinsand noted that no serious negotiations took place, the report carries low credibility. The Phillies likely require bullpen reinforcements, especially after the loss of Alvarado, making their interest in Robertson a logical consideration. However, Robertson remains a free agent, raising questions about his market value given his previous effectiveness last season.

Another report from Bob Nightengale of USA Today suggested that the Los Angeles Dodgers and Chicago Cubs are closely monitoring third baseman Ryan McMahon, who could be on the move from the Colorado Rockies. This assessment is marked as high on the BS Meter due to the Rockies’ history of not engaging in significant trades, even in challenging seasons. McMahon's performance has been subpar, hitting .211 with a .706 OPS, and his contract may deter teams from pursuing him. Despite the interest from the Dodgers and Cubs, the likelihood of a trade without financial concessions from the Rockies appears minimal.
