Fantasy baseball guru Tristan Cockcroft flags five players whose value could evaporate fast. Center‑field star Byron Buxton has dazzled with 61 homers and 29 steals in 181 games but missed 48 contests, raising durability concerns. His 2.86 fantasy points per game rank 14th among qualified hitters, yet his injury history suggests a looming drop‑off. Managers should act now this season.

Relief ace Riley O'Brien rode a 13‑appearance scoreless streak before his ERA ballooned to 8.31 and he blew three saves. The Cardinals sit atop the NL wild‑card, but their championship odds lag, meaning fewer save opportunities. O'Brien’s lack of dominant stuff and the team’s shaky outlook make him a trade target before his stock sinks.

Third‑base/first‑base hybrid Liam Hicks stays valuable despite a 30‑point batting‑average slide and low exit velocity. His volume keeps him in the top‑20 catcher‑eligible spots, but a hot streak from Miami’s Joe Mack or Agustín Ramírez could cut his minutes. Pitchers Emerson Hancock and Ryan Weathers face roster pressure; Weathers, eyed for a bullpen shift, carries injury risk and should be moved before his innings pile up.
