The Braves have added three more pitchers to their list of non-roster invitees, as relayed by Justin Toscano of the Atlanta Journal-Constitution. They are left-hander Jake Diekman as well as righties Dylan Covey and Chad Kuhl. MLBTR covered the Kuhl deal last week.
Diekman, 38, has a long track record of walking a tightrope with a lot of strikeouts but also a lot of free passes. In 602 1/3 innings of relief dating back to his 2012 debut, he has allowed 3.91 earned runs per nine. His 28.7% strikeout rate in that time is a few ticks above average and his 46.9% ground ball rate around par, but his 13.4% walk rate is definitely on the high side.
He’s coming off a down year. He signed a $4MM deal with the Mets but was released in early August. He had a 5.63 in 32 innings. His 27.6% strikeout rate was near his usual range but his 16.6% walk rate was high, even for him. Among pitchers with at least 30 innings pitched last year, only youngsters Nick Nastrini and Joe Boyle had higher walk rates. He didn’t sign anywhere else for the final two months of the season.
Upgrading the bullpen has been a priority for Atlanta this offseason. They lost guys like A.J. Minter, Jesse Chavez and others to free agency at season’s end. In early November, it was reported that Joe Jiménez might miss all of 2025 while recovering from knee surgery.
Seemingly operating with a tight budget, they haven’t been too active in pursuing upgrades to the relief mix. Anderson Pilar was brought in via the Rule 5 draft and is arguably the most notable addition to this point.
They don’t specifically need a lefty, as they already have Dylan Lee, Aaron Bummer and Angel Perdomo in the mix, but Diekman doesn’t have huge splits regardless. Lefties have a .229/.344/.311 line against him in his career whereas righties have hit .210/.329/.357. He’s not coming off a great season but he adds some experienced depth for cheap, and without taking up a roster spot for now.
Covey, 33, is coming off a mostly lost season but had some intriguing results the year prior. After spending 2021 and 2022 pitching for the Rakuten Monkeys in Taiwan’s Chinese Professional Baseball League, he split 2023 between the Dodgers and Phillies. He logged 43 innings between those two clubs with a 3.77 ERA. His 15.7% strikeout rate was low but he got grounders on 54.3% of balls in play.
A shoulder strain kept him on the shelf for most of 2024. He didn’t pitch in the majors at all and was limited to 20 1/3 innings on the farm. 15 of those innings were at the Triple-A level with intriguing results in a small sample. He had a 1.20 ERA at that level, 27.6% strikeout rate, 12.1% walk rate and 71.4% ground ball rate.
The Phils had outrighted him off their roster in August and he elected free agency at season’s end. He signed a split deal with the Mets but was recently outrighted off that club’s roster and elected free agency. Like Diekman, he’ll give Atlanta some cheap rotation depth without taking up a roster spot for now.
