The Arizona Diamondbacks officially announced the signing of reliever Hector Rondon this morning. This required room to be cleared on the 40-man roster, and the unlucky man left without a seat when the music stopped was right-handed reliever Jimmie Sherfy. It completes a startling fall from grace. For Sherfy’s major-league career began with 14 consecutive scoreless appearances, and through his first 36.2 innings, Jimmie had an ERA of below one.
Despite this, Sherfy was unable to command a regular bullpen position in 2019, despite many people calling for him to be brought up from Reno. Matters weren’t helped by Jimmie missing time through injury, but when rosters expanded in September, he finally joined the big club. Unfortunately, the results were awful: over 8.2 innings, he allowed 12 hits, including four home-runs, leading to 11 earned runs. While his K:BB was an impressive 13:0, Sherfy’s velocity had dropped considerably. In September 2019, his fastball averaged 92.1 mph, down from 94.4 mph in 2017. Still, I’m sure there are a lot of people who’d probably prefer to have seen, say, Matt Andriese put on the bus to Greenland, rather than Sherfy.
The team now has 10 days to figure out a trade for Sherfy, or see if any other team puts a waiver claim in. In the (probably fairly unlikely) event that neither happens, he’ll be taken off the Diamondbacks’ 40-man roster and can be retained in the minors. But it seems almost certain that some other team will take a flier on Sherfy, one way or another, and as a result, we have probably seen the last of his time in Arizona.
