Amidst a rebuild, the Arizona Diamondbacks are lastly seeing the fruits of their labor. Led by promising starters Zac Gallen, 2.54 ERA in 184 innings, and Merrill Kelly, 3.37 ERA in 200 1/3 innings, and backed offensively by a quartet of promising younger outfield expertise, Alek Thomas, Daulton Varsho, Jake McCarthy, and Corbin Carroll, the D-Backs are shortly re-entering a aggressive window.
Nevertheless, the Diamondbacks’ bullpen remains to be falling flat. After signing Mark Melancon to a 2-year, $12MM contract ($5MM mutual possibility for the 2024 season, $2MM buyout) and Ian Kennedy to a 1-year, $4.5MM contract ($4MM membership possibility for the 2023 season, $250K buyout), the D-Backs’ pen posted the sixth-highest ERA (4.58), the eighth-most blown saves (27), the bottom strikeout fee (19.7%), and allowed the third-highest batting common (.254). Veterans Melancon and Kennedy didn’t fare significantly better. Melancon pitched to a 4.66 ERA in 56 innings with a paltry 14.2% strikeout fee and a career-worst 43.2% floor ball fee, whereas Kennedy pitched to a 5.36 ERA in 50 1/3 innings with a weak 19.0% strikeout fee and a particularly low 24.4% groundball fee.
Nevertheless, the breakout of lefty journeyman Joe Mantiply was a shiny spot amongst an in any other case weak bullpen efficiency. Mantiply, a former Twenty seventh-round decide from Virginia Tech by the Tigers in 2013, reached the majors for a fast stint in 2016, earlier than shuffling round numerous minor league groups and present process Tommy John surgical procedure in 2018. He signed a minor league cope with Arizona in 2020, making one other brief look in 2020 earlier than finally becoming a member of the crew in a extra long-term style throughout the 2021 season, by which he pitched 39 2/3 innings to a 3.40 ERA with opponents hitting a powerful .292/.358/.448 in opposition to him.
Within the 2022 season Mantiply, who’s controllable by the 2026 season, improved his 2021 numbers. Pitching to a low 2.85 ERA in 60 innings with a stable 25.1% strikeout fee, a glowing 2.5% stroll fee, and lacking hitters’ barrels (99th percentile for Chase Fee, 94th percentile for Barrel %), the 31-year-old earned a visit to the All-Star recreation in his second full season. Left-handed hitters have discovered restricted success in opposition to Mantiply, slashing a poor .247/.297/.282 in opposition to him, whereas righties are hitting a barely higher .260/.272/.404. The unpleasant .252 mixed common could also be trigger for concern, nevertheless, Mantiply is tied for the Twenty seventh lowest Onerous Hit%, amongst relievers to pitch 50+ innings, and is within the 89th percentile for Common Exit Velocity.
The Diamondbacks will seemingly look to deal with their bullpen once more this offseason, however with a high-leverage lefty reliever in Mantiply, they are going to have one much less bullpen spot to fill.
