The MLB trade deadline is fast approaching, and the St. Louis Cardinals are poised to be key players in the market, particularly regarding their pitching staff. Among the names being discussed, closer Ryan Helsley stands out as a leading candidate to be traded, ranked No. 23 among prospects with a 30% chance of departure. This season, Helsley has struggled, as evidenced by his 1.444 WHIP, suggesting a decline in performance. The Dodgers, Phillies, Yankees, Tigers, and Diamondbacks could be potential suitors, all of whom are in contention for the wild card.

Additionally, Phil Maton could step into the closer role should Helsley be traded; he has shown reliability this season. The Cardinals may also look to trade Erick Fedde and Steven Matz, with Fedde showing a 50% chance of being moved, especially with his performance regressing this year. Matz, on the other hand, has improved his command but carries injury concerns. The Cardinals, currently performing well, might also consider adding to their roster, depending on how the trade landscape unfolds.
