Guardians Place Triston McKenzie On IL With Elbow Sprain

8:44pm: As noted by Paul Hoynes of Cleveland.com, manager Terry Francona told reporters that an MRI revealed that McKenzie was suffering from inflammation in his right elbow, with Francona noting that the inflammation “means the UCL is involved.” It’s obviously less than ideal news for McKenzie, as UCL issues can often require Tommy John surgery, though it’s certainly possible that this issue won’t rise to that level. Per Francona, McKenzie will head back to Cleveland to be examined by team staff before the club determines next steps.

6:30pm: The Guardians are making a series of roster moves ahead of tonight’s game against the Diamondbacks, as noted by Zack Meisel of The Athletic. The club is placing right-hander Triston McKenzie on the injured list with a right elbow sprain, designating right-hander Touki Toussaint for assignment, selecting the contract of left-hander Daniel Norris, and recalling left-hander Tim Herrin from Triple-A. Meisel also notes that the club is recalling catcher Bo Naylor, as previously expected.

McKenzie, who was scratched from yesterday’s start with elbow discomfort, now heads to the IL with a sprain in his right elbow. While further details have not yet been made available, it’s certainly an ominous diagnosis for the 25-year-old hurler, particularly after missing the first two months of the season with a teres major strain. McKenzie made just two starts before returning to the IL, striking out ten over five scoreless innings against the Twins before getting lit up for five runs in five innings against the Astros at home last week.

Of course, McKenzie was a key factor in Cleveland’s success last season as he threw 191 1/3 innings with a 2.96 ERA and 3.59 FIP. McKenzie posted an excellent 25.6% strikeout rate against a walk rate of just 5.9% as he helped to lead the Guardians to a surprising AL Central crown before the club fell to the Yankees in the ALDS. The club has struggled to replicate its 2022 campaign this year, with a record of just 32-37 that leaves them three games back of the Twins in a weak AL Central division.

Some of those struggles can be attributed to the uncertainty facing the club’s starting rotation, as only Shane Bieber has managed to stay healthy and effective as a starter throughout the entire season to this point, though youngsters Logan Allen and Tanner Bibee have done well following in-season promotions. Unfortunately, that uncertainty appears poised to continue with McKenzie headed back to the injured list with what could be another lengthy absence, though his timetable for return will remain uncertain until the club provides additional clarity on the situation.

Joining the club’s pitching staff as McKenzie exits is a pair of left-handers. Herrin, a 26-year-old who made his MLB debut for the Guardians earlier this season, struggled to a 6.39 ERA and 4.54 FIP in ten major league appearances but has posted more palatable numbers at the Triple-A level with a 3.93 ERA in 18 1/3 innings of work. Norris, meanwhile, signed with the Guardians on a minor league deal back in March. He’s struggled to a 6.93 ERA in 14 appearances (nine starts) at the Triple-A level this season, though the veteran has pitched in parts of nine major league seasons and has been roughly league average by measure of ERA+, with figure of 99 in 569 2/3 career innings of work.

Making room for Norris on the active roster is Toussaint, who departs the Guardians after making a spot start last night in McKenzie’s stead. The 27-year-old former first round pick allowed two runs on three hits and five walks over 3 2/3 innings of work while striking out two against the Diamondbacks yesterday. The Guardians now figure to either attempt to swing a trade involving the right-hander or attempt to pass him through waivers. If successful in doing so, Cleveland could outright Toussaint to Triple-A, where he would continue to serve as pitching depth for the club going forward.
