Edwin Diaz‘s recent injury has forced the Mets to confront a looming void at the back end of their bullpen. The team now eyes how Los Angeles might leverage Riley O’Brien as insurance, a move that could reshape the closer market ahead of the trade deadline.
Jeff Passan reported that the Dodgers could use O’Brien, a 31‑year‑old reliever who posted a 3.95 ERA and allowed just 11 earned runs over 48 innings in 2025, as a contingency for Diaz. The article notes that the Dodgers are also weighing a bid for ace Tarik Skubal, but O’Brien offers a cheaper, proven sinker‑slider combo to replace Blake Treinen long‑term. The numbers suggest O’Brien’s 2025 performance ranks among the Cardinals’ best relievers, making him an attractive insurance policy for a club dealing with an injured closer.
The Mets must decide whether to pursue a trade, negotiate a waiver claim, or develop internal arms to fill the gap. For complete coverage, see Dodgers Eye O’Brien to Boost MLB Closer Rankings Race.
