The Diamondbacks announced today that right-hander Zach Davies has been placed on the 15-day injured list due to lower back inflammation, with left-hander Joe Mantiply recalled in a corresponding move.
It’s been a frustrating season for Davies, 30, whom the D’Backs re-signed to a $5MM deal in the winter. He made just two starts earlier in the season before getting sidelined by an oblique strain that put him out of action for about six weeks. He returned at the end of May and has made 10 more starts but has a 7.38 on the year overall and is now back on the injured list yet again. A 51.7% strand rate is probably making his ERA worse than he deserves, though his 17.8% strikeout rate and 10.4% walk rate are both worse than league average.
Davies isn’t the most essential piece of the roster in Arizona but his loss compounds a rotation issue that stands out as a weak point for the club. Merrill Kelly is also on the injured list due to a calf injury, though he could return to the club in the next week, per Steve Gilbert of MLB.com.
Even with Kelly back and Zac Gallen atop the rotation, the rest of the picture is a little shaky. Tommy Henry has a 3.89 ERA but his peripherals aren’t great, leading to a 5.08 FIP and 5.24 SIERA. Ryne Nelson has a 4.98 ERA for the year. Prospect Brandon Pfaadt has struggled in his opportunities with a 9.82 ERA on the year so far.
It’s unclear how long Davies is expected to be out but will undergo an MRI tomorrow, relays Gilbert. Regardless of the severity of the issue, his absence seemingly only enhances the club’s need to add starting pitching at the deadline, something that general manager Mike Hazen has already admitted will be a priority. The club was leading the National League West for much of the year but has since slid to third place behind the Dodgers and Giants, though they do still possess a Wild Card spot. The August 1 trade deadline is now less than two weeks away.
