Marlins DFA John King, Call Up Jack Ralston in Bullpen Shakeup

The Marlins designated veteran reliever John King for assignment on Aug 23 after his August collapse (13.50 ERA, 11 ER in 9.2 IP). They recalled right-hander Jack Ralston from Triple-A, who dominated with a 1.66 ERA, 75 K in 59.2 IP, and a 31.1% K rate. Ralston made his MLB debut on Aug 23, pitching solidly. His walk rate is a concern, but he adds a fresh arm to the bullpen as the Marlins push for a wild card spot. This move continues the bullpen reshuffling after Andrew Nardi's season-ending surgery and Pete Fairbanks' recent struggles. Michael Petersen has also emerged as a reliable option, earning a win on Aug 23.
