The St. Louis Cardinals are actively seeking to bolster their rotation ahead of the July 30 trade deadline as they sit just half a game behind a National League Wild Card spot. Although they missed out on acquiring Zach Eflin, who was traded from the Tampa Bay Rays to the Baltimore Orioles, the Cardinals have shown interest in several other pitchers, including Toronto's Chris Bassitt, Chicago's Erick Fedde, and Detroit's Tarik Skubal. The Cardinals' pursuit indicates a clear intent to strengthen their pitching staff, crucial for their postseason ambitions. Meanwhile, the Tampa Bay Rays have adopted a seller's stance, trading Eflin and star outfielder Randy Arozarena to focus on future prospects. Additionally, the Arizona Diamondbacks made a strategic move by acquiring relief pitcher AJ Puk from the Miami Marlins to enhance their bullpen for their playoff push.
