The Diamondbacks have agreed to a minor league contract with right-hander Jandel Gustave, tweets Robert Murray of FanSided. He’ll be invited to big league camp this spring.
The 30-year-old Gustave has spent the past two seasons with the Brewers, turning in solid bottom-line results despite some shakier secondary marks. Gustave carries a 3.69 ERA in 46 1/3 innings over 41 games with Milwaukee dating back to 2021, and he’s averaged a hearty 96.7 mph on his heater during that time. Fielding-independent marks are a bit more skeptical of his efforts, albeit not overwhelmingly so (4.52 FIP, 3.94 SIERA).
Despite his strong velocity, Gustave owns a sub-par 20.1% strikeout rate since 2021. His 8% walk rate during that time is a bit better than average. It’s worth noting that he did up his strikeout rate in 2022 (22.5%), but that was accompanied by an uptick in walks as well (9.2%). Gustave wasn’t particularly homer-prone with the Brewers (1.17 HR/9), and his overall 48.2% ground-ball rate (50% in ’22) is also comfortably ahead of the 42.9% league average.
Injuries played a part in Gustave’s departure from the Brewers. A strained right hamstring cost him more than a month in the first half of the 2022 season, and he was placed on the injured list on Aug. 2 with a forearm injury that wound up ending his season. Gustave never wound up requiring surgery, but his final pitch of the 2022 season nonetheless came on July 31. The Brewers non-tendered him back in November despite the fact that he had two years of club control remaining and a projected salary of just $900K (via MLBTR contributor Matt Swartz).
Assuming he’s healthy, Gustave figures to have a decent chance to crack the D-backs’ bullpen at some point, whether it be on Opening Day or early in the season. Arizona has a generally unsettled mix of relievers, with a few exceptions. Lefty Joe Mantiply had a breakout showing in 2022, and the Snakes will hope for better results from veteran Mark Melancon in the second season of a two-year deal. Veteran Miguel Castro was signed a to a one-year deal earlier in the winter, and 28-year-old righty Kevin Ginkel (29 in March) impressed in 29 1/3 innings down the stretch after posting rough results in 2020-21. The Diamondbacks also once again tapped into the NPB/KBO market by signing former Marlins righty Scott McGough to a two-year contract on the heels of a terrific four-year run in Japan.
Beyond those names on the 40-man roster, Gustave will join Jeurys Familia as a non-roster invitee of particular note this spring. Other minor league signees with varying levels of MLB experience in the bullpen include Austin Adams, Austin Brice, Jesse Biddle, Sam Clay, Ryan Hendrix, Zach McAllister and Eric Yardley.
