The Diamondbacks are pulling Paul Sewald from the closing role, manager Torey Lovullo announced before Friday's game against the Pirates (X link via Steve Gilbert of MLB.com). Lovullo did not immediately name a replacement, suggesting the team could go with a committee approach.
Friday's game provided an immediate test. Arizona coughed up an early 5-0 lead but bounced back to take a two-run lead into the ninth. Lovullo tabbed sidewinder Ryan Thompson to close it out. Thompson gave up a couple of singles and a run but successfully locked down a 9-8 victory. That usage could indicate the sinkerballer will get the bulk of the closing chances, though Arizona needed to use high-leverage arms Kevin Ginkel, A.J. Puk, Dylan Floro and Justin Martinez just to get it to the ninth.
In any case, the Snakes won’t give every narrow ninth-inning lead to Sewald. The veteran right-hander had been almost spotless between his early May season debut through the end of June. He carried a 0.54 ERA over 16 2/3 frames. Sewald locked down his first 11 save chances in the process.
Things unraveled for him almost immediately once the calendar turned to July. Sewald gave up multiple runs and blew the lead in each of his first three outings of the month, all of which ended up being Arizona losses. He rebounded with five straight scoreless appearances, but he’s given up runs in three of his four most recent games.
Sewald blew a save in what turned out to be an extra-inning loss to Pittsburgh on Saturday. He got the call on Wednesday to hold a 5-2 lead against the Nationals but put four of five runners aboard (three via walk). Thompson came on and ended up securing a 5-4 win. That’s technically a hold for Sewald but obviously not a good performance.
The nightmarish few weeks came largely out of nowhere. Sewald has been one of the best relievers in MLB since his breakout with the Mariners in 2021. He turned in a 2.88 ERA over parts of three seasons in Seattle. Arizona’s call to send Josh Rojas, Dominic Canzone and Ryan Bliss to the M’s at last year’s deadline added needed stability to the back end of the bullpen.
It ended up being one of the biggest moves in the D-Backs’ surprising pennant run, as Sewald picked up 13 saves with a 3.57 ERA down the stretch. He wasn’t missing quite as many bats as he had in Seattle, but Sewald had a 2.10 ERA with a 25.2% strikeout rate over 34 1/3 innings as a Diamondback until last month. He is an impending free agent, so his performance down the stretch is especially important for him personally.
Arizona made a big deadline move for bullpen help for the second straight year, bringing in Puk for a pair of prospects last month. They swung a more minor deal for Floro minutes before the deadline on Tuesday evening. That gives them some cover to allow Sewald to work through this funk in lower-leverage spots.
The D-Backs are trying to hang onto a wild-card spot in what remains a crowded National League field. They’re riding a four-game win streak to get a season-high eight games over .500 but are only one game clear of the Mets, the top non-playoff team at the moment.
Two big factors in their potential pennant push: Eduardo Rodriguez and Merrill Kelly. Arizona has been without two of their top starters for the bulk of the season. Rodriguez has yet to make his team debut after sustaining a lat strain in spring training. Kelly went down in mid-April with a shoulder strain.
The D-Backs could get a boost from both pitchers. Rodriguez should be reinstated from the 60-day injured list to start next Tuesday’s game against the Guardians, tweets John Gambadoro. Meanwhile, Gilbert relays on X that Kelly is slated to start a rehab stint that same night with High-A Hillsboro. That’d likely kick off a few-week rehab process before he’s ready to get back on the mound at Chase Field.
Arizona did get a couple less encouraging updates on the pitching staff, though. Nick Piecoro of the Arizona Republic tweets that reliever Bryce Jarvis is likely to miss the rest of the season with an elbow sprain. The former first-round pick is not expected to require surgery but will need to be shut down from throwing. Jarvis has worked in a low-leverage relief role, tossing 59 1/3 frames of 3.19 ERA ball. His strikeout and walk profile is a lot less impressive than that ERA, but the Duke product has been a bullpen workhorse.
Rookie right-hander Cristian Mena is also likely done for the season. Alex Weiner of AZ Sports reported on Tuesday that the 21-year-old suffered a forearm strain in Triple-A (X link). Mena, who made his MLB debut last month with a three-inning spot start, is on the minor league injured list but could move to the 60-day IL if the Snakes need a 40-man roster spot. The Diamondbacks acquired him over the winter in a one-for-one swap sending outfielder Dominic Fletcher to the White Sox.
