Caleb Smith

Diamondbacks lefty Caleb Smith has been a diagnosed with a ligament tear in his left elbow, Nick Piecoro of the Arizona Republic reports. However, after receiving multiple opinions on the injury, he’ll first opt for a rest-and-rehab approach rather than immediately undergoing Tommy John surgery, GM Mike Hazen tells Piecoro. The team has not provided a timetable for Smith’s potential recovery.

As with any tear, the possibility of eventual surgery will linger as Smith works through the rehab process. However, given the timing of the injury — Smith pitched in the D-backs’ final game of the season but departed with a trainer — he’d have been in line to miss the entire 2023 campaign even if he’d undergone surgery right away. If the tear is minimal enough that doctors feel he has a chance for it to heal without surgery, there’s little reason for him not to try the rehab route before going under the knife. That at least leaves the door open for him to pitch in 2023, and if he has surgery in a couple months’ time anyhow, he’d still be on track for an early 2024 return.

Regardless of whether he eventually requires surgery or is successful in rehabbing the tear, it’s quite possible that the ligament issue will bring an end to Smith’s tenure with the Diamondbacks organization. The 31-year-old southpaw is eligible for arbitration for the third and final time this winter, and MLBTR contributor Matt Swartz projects him to receive a raise from $2MM to $2.7MM. With the specter of major surgery looming in a worst-case scenario and a presumably months-long rehab process on the docket even in a best-case scenario, Smith becomes an even clearer non-tender candidate than he already was.

Smith has had an up-and-down tenure in Arizona, splitting time between the bullpen and rotation with a few promising stretches but a general lack of consistency. He looked like a viable trade candidate for the D-backs early in the summer of 2021, pitching to a 3.08 ERA with a 26.9% strikeout rate (albeit against a bloated 11.6% walk rate)  in 64 1/3 innings. Smith, however, was blown up for an ERA north of 12.00 over his next six starts, causing him to lose the rotation spot he’d seized at the beginning of June.

A solid finish out of the bullpen in 2021 (2.70 ERA in 26 2/3 innings) kept Smith in the team’s plans and set the stage for him to occupy a bullpen role full-time in 2022. He gave the Snakes 70 innings of 4.11 ERA ball this past season but did so with the worst full-season strikeout and walk rates of his career (21.5% and 12.9%). Since his Aug. 2021 shift to the bullpen, Smith has a solid 3.72 ERA but lackluster marks in strikeout rate (21.5%), walk rate (12%), ground-ball rate (30.6%), homers per nine innings (1.68), FIP (5.28) and SIERA (4.60).

Diamondbacks lefty Caleb Smith was ejected after the eighth inning of last night’s game against the Phillies after the umpiring crew believed to have detected a foreign substance on his glove.  His glove will now be sent to the league headquarters for further examination, which could result in a 10-game suspension. Smith, who pitched 2 2/3 innings and had already cleared one check at the end of the sixth inning, vehemently argued his case as the umpiring crew spoke with manager Torey Lovullo (video link).

The 28-year-old Smith becomes just the second player ejected under the league’s new foreign-substance crackdown. If he’s suspended, as was the case with Mariners lefty Hector Santiago, the Diamondbacks would not be able to replace him on the roster over the course of his suspension.

Speaking to reporters after the game, Smith was understandably quite upset, and manager Torey Lovullo defended his player (Twitter links, with video, via Cameron Cox of 12 News in Arizona). Smith was adamant that if he’d cheated, he “would own up to it” and expressed anger that the ejection itself “drags my name through the mud” even though he does not ultimately believe he’ll be suspended.

“I’m not stupid,” Smith said. “I know the main two things they check are your glove and your hat. Even if I was using something, which I wasn’t, I wouldn’t put it in my glove or my hat. I mean, that’s just ignorant.”

Lovullo offered immediate support for his left-hander. “I’m always going to side with the player when he looks me square in the eyes and tells me that [he’s not cheating],” the manager said. “…I believe my player. I stand by my player. He told me there was nothing malicious happening. I asked to see his hand, and his hand was bone dry. … You can see Caleb goes to the ground a lot to get dirt on his hands. He has a pile of dirt on the side of his pantleg as a result of wiping down the dirt.”

Asked whether he was allowed to see and/or touch the glove, Lovullo acknowledged that it was “a little bit sticky” inside the heel of the glove but said there was no “huge buildup” and maintained his belief that it was a combination of sweat, rosin and dirt.

It’s now up to the league’s jurisdiction to determine whether there was or was not a foreign substance on Smith’s glove. Notably, however, ESPN’s Jesse Rogers reported after Santiago’s prior suspension that the league did not even further examine Santiago’s glove — instead issuing a suspension based solely on the umpires’ reported detection of a foreign substance (Twitter link). The crew chief in last night’s game, Tom Hallion, was also the crew chief at the time of Santiago’s ejection (and subsequent suspension). Via The Athletic’s Zach Buchanan, umpire Phil Cuzzi inspected Smith’s glove both at the end of the sixth inning, when he was cleared, and at the end of the eighth inning, when he was ejected.
