Arizona Diamondbacks: Fernando Rodney

The odds were good that Rodney, a 40-year-old with his sixth team in the last five years, would prove this season’s first deposed closer, particularly with newly minted relief weapon Archie Bradley breathing down his neck. But Rodney held on to the job all year, converting 39 of 45 save chances. His half-dozen blown opportunities, though, tended to come in spectacular meltdown fashion—he was blasted for 16 earned runs over just four total innings in those, permitting just 10 earned in his other 54 appearances. With Bradley locked in a high leverage middle innings role, the end of games will belong to Rodney. Arizonan fingernails will be chewed.
