Guthrie, 37, opted out of his minor league contract with the Padres earlier this month. He put up some ugly numbers with Triple-A El Paso, exiting with a 6.60 ERA and a 37/19 K/BB ratio in 60 innings. That’s on the heels of a lackluster performance in 24 starts and six relief appearances with the Royals last year, compiling a 5.95 ERA.
Guthrie may not be an effective major league pitcher anymore but he can still, at the very least, provide depth for the Marlins. That could prove valuable later in the season, especially if the Marlins decide to ease off the gas pedal with Jose Fernandez.
