Diamondbacks Place Zach Davies On 15-Day IL, Select Peter Solomon

1:30PM: Jameson will move into Davies’ rotation spot, manager Torey Lovullo told reporters (including Theo Mackie of the Arizona Republic).

12:45PM: The Diamondbacks announced that right-hander Zach Davies has been placed on the 15-day injured list, due to a strained left oblique suffered in last night’s game with the Dodgers.  Right-hander Peter Solomon’s contract was selected from Triple-A in order to fill Davies’ spot on the active roster.  Arizona moved both Mark Melancon and Cole Sulser to the 60-day IL to create 40-man roster space for Solomon and for the newly-acquired Jose Ruiz.

It was pretty clear that Davies was headed to the IL after yesterday’s early exit, as he struggled through 4 1/3 innings before departing.  We may learn about the severity of Davies’ strain in due time, though most oblique injuries of even a Grade 1 level usually require around a month of recovery time.

Since the D’Backs don’t play on Thursday, the team doesn’t strictly need a fifth starter until its April 18 game against the Cardinals.  That gives the Snakes some time to figure out Davies’ replacement in the rotation, with reliever Drey Jameson representing the most obvious in-house option already on the MLB roster.  Jameson didn’t win a rotation job in Spring Training but still made the roster as a relief pitcher, with the expectation that he could step into a starting role if and when an injury-related vacancy emerged.  At the Triple-A level, Tommy Henry and top prospect Brandon Pfaadt are also possibilities if the D’Backs prefer to keep Jameson in the bullpen.

Solomon’s promotion could be a hint to Arizona’s intentions, as while Solomon is a starter himself, his shaky results in the minors might suggest that he’s suited to a relief role at the MLB level.  The Diamondbacks might move Jameson to the rotation and then use Solomon in Jameson’s role as a multi-inning reliever (albeit in lower-leverage situations).

Solomon was a fourth-round pick for the Astros in the 2017 draft, and his only MLB experience came in the form of 14 innings with Houston in 2021.  Pittsburgh claimed Solomon off waivers from the Astros last September, and then Arizona selected Solomon away from the Pirates in December during the minor league version of the Rule 5 Draft.  While Solomon has a 5.25 ERA over 210 2/3 innings at the Triple-A level, he misses a lot of bats, and might better fit the profile of a reliever even though he has a five-pitch arsenal.

It was only a matter of time before the D’Backs moved Melancon to the 60-day IL, since the veteran reliever is expected to miss several months recovering from a shoulder strain.  Sulser is also suffering from a shoulder strain and was just placed on the 15-day injured list on Friday, but he’ll now face at least a two-month absence before he returns to the big league roster.

The mounting list of injuries in Arizona’s bullpen might also be a factor in the team’s decision about whether or not to move Jameson out of a relief spot.  Corbin Martin might miss the entire 2023 season after undergoing lat tendon surgery last month, Melancon and Sulser are also long-term absences, and Joe Mantiply began the season on the 15-day IL due to shoulder fatigue.
