What happened: Jon Heyman flagged more than 20 name players who could move in trades and framed the market around which clubs are most or least likely to sell. The source specifically names the New York Mets, Boston Red Sox, New York Giants and Houston Astros as teams under that deadline lens.
Why it matters: The report matters because early-June records are forcing clubs with preseason ambitions to decide whether to chase the postseason or convert veterans into future value. MLB's trade deadline is still weeks away, but clubs hovering below .500 can shift the market quickly once front offices stop waiting for a turnaround.
By the numbers: As of June 5, StatMuse listed the Mets at 24-33 (.421), 14.5 games back; the Giants at 22-35 (.386), 15.0 games back; the Red Sox at 23-33 (.411), 13.0 games back; and the Astros at 26-33 (.441), 3.5 games back.
What to watch: Watch whether any of the four teams can close ground before the deadline calculus hardens. A June surge could delay selling; another poor stretch could push front offices toward outbound deals.
