Zach Eflin

Orioles right-hander Zach Eflin left his start this afternoon after just one inning due to what Baltimore later announced as lower back tightness. After the game, manager Tony Mansolino spoke to reporters (including Jake Rill of MLB.com) and revealed that Eflin had actually felt the tightness during his pregame bullpen session, but that he thought he could pitch through it. As noted by Matt Weyrich of the Baltimore Sun, Eflin wanted to go back out for a second inning after surrendering four runs in the first on 28 pitches, but the team’s coaches pulled him from the game. Mansolino added that the club is not yet certain whether or not Eflin will require a trip to the injured list and that he could be sent for imaging to determine the severity of the injury.

Needless to say, it’s tough news for Baltimore. Eflin entered the season as the club’s de facto ace after the losses of Kyle Bradish to injury and Corbin Burnes to free agency. He found success early on with a 3.00 ERA in his first three starts, but missed over a month due to a lat strain. Since returning, he’s pitched to a 7.13 ERA in 44 innings including today’s abbreviated outing. Even ignoring today’s start, Eflin has posted figures north of 6.00 in both ERA and FIP since returning from the shelf. He’s also struck out just 17.6% of his opponents and surrendered 13 homers in just eight starts. His results have been so disastrous since his return from the shelf back in May that it’s fair to wonder if a stint on the injured list could be a necessary reset for the 31-year-old.

The Orioles fell to a disappointing 35-47 record with their loss today, but the front office has not yet committed to selling as they hold out hope for a hot streak that could put them back into the playoff conversation. Each loss makes that sort of run less and less likely to occur, however, and whether the Orioles end up winning enough games to stay in the race or sell off rental players at the deadline, a healthy and effective Eflin figures to be a big part of either of those plans. Chayce McDermott and Brandon Young are among the players who could be called upon to fill in for Eflin if he heads to the injured list.

Eflin looked like he could be one of the more attractive rental starters on the market this summer, but at this point it seems likely that Tomoyuki Sugano and his 4.06 ERA in 16 starts will be the most attractive rental arm in Baltimore’s rotation. Even 41-year-old veteran Charlie Morton may garner more interest than Eflin at this point, as he’s managed to turn things around after a brutal start with a 3.21 ERA over his past 12 appearances and a 2.90 ERA since returning to the rotation on May 26. On the other hand, it’s fair to note that Morton’s turnaround over the past month could certainly happen for Eflin in the run up to the deadline. That would likely require him to avoid the injured list, however, as even a minimum stint on the shelf at this point would leave him sidelined until after the All-Star break.

April 9: Eflin has formally been placed on the injured list, retroactive to yesterday, the team announced this morning. Righty Colin Selby is up from Triple-A Norfolk for the time being, giving Hyde an extra arm in the bullpen.

April 8: The Orioles are shutting Zach Eflin down for a week after he was diagnosed with a low-grade lat strain, manager Brandon Hyde told reporters following tonight’s loss in Arizona (relayed by Andy Kostka of The Baltimore Banner). The righty will land on the 15-day injured list.

Eflin felt the discomfort during Monday evening’s start. He tossed six innings of one-run ball before departing at 73 pitches. Baltimore announced that he was battling shoulder fatigue and sent him for imaging. A one-week shutdown is far from the worst case scenario, but the O’s will go at least a couple weeks without their Opening Day starter.

Baltimore is now operating without arguably their three best pitchers. They knew they wouldn’t get much, if anything, from Kyle Bradish this year after he underwent Tommy John surgery last June. Grayson Rodriguez went down in Spring Training with elbow inflammation. He’s throwing but hasn’t progressed to a minor league rehab assignment.

The O’s have Charlie Morton, Dean Kremer, Tomoyuki Sugano and Cade Povich in the rotation. They brought back Kyle Gibson on a one-year contract late in Spring Training. He isn’t yet ready for major league action. Gibson agreed to begin the season with Triple-A Norfolk to continue his build-up. He’ll make his first start there on Thursday.

Aside from Gibson, the O’s have prospect Brandon Young as their only depth starter on the 40-man roster. Young has only allowed two unearned runs while striking out 11 over his first two Triple-A starts this year. Thaddeus Ward, who made 26 relief appearances as a Rule 5 pick for the Nationals two seasons ago, is also working out of the Norfolk rotation. Cody Poteet and Roansy Contreras are working out of the bullpen in Triple-A but have some starting experience in the majors. The O’s have off days on Thursday and Monday, so they could get by with four starters into the second half of next week.

None of those pitchers can be expected to match Eflin’s production, of course. The 31-year-old righty managed an earned run average around 3.50 in both 2023 and ’24. He’d posted an even 3.00 ERA while working six innings per start over his first three appearances of this season.

The Orioles placed Zach Eflin on the 15-day injured list, retroactive to August 17, on account of shoulder inflammation. Baltimore also placed Keegan Akin on the paternity list. Rookie Cade Povich and reliever Dillon Tate are up from Triple-A Norfolk to take the open spots on the active roster.

Baltimore acquired Eflin in their biggest move at the deadline. The righty had carried a 4.09 earned run average through 19 starts with the Rays in the season’s first half. He has gotten out to a fantastic start to his O’s tenure. Eflin has surrendered only six runs through his first four starts. He’s averaging nearly 6 1/3 innings per appearance and has turned in a stellar 25:2 strikeout-to-walk ratio.

That positions Eflin as the O’s #2 or #3 starter in a hypothetical playoff series. Corbin Burnes would surely get Game 1, while Eflin and Grayson Rodriguez are the presumptive choices for the next two appearances if they’re healthy. Both pitchers are currently on the injured list, though it doesn’t seem Eflin’s issue is as worrisome as Rodriguez’s is. While the youngster is shooting for a late September return after sustaining a lat strain, Eflin might not miss much more than the minimum 15 days. Skipper Brandon Hyde told the Baltimore beat he’s hopeful that it’ll be a short-term stay (X link via Roch Kubatko of MASNsports.com).

Even a brief absence could have a significant impact on the AL East race. Baltimore is only half a game behind the Yankees for both the division lead and the best record in the American League. The O’s rotation depth has long been the biggest question mark on a very strong roster. With Kyle Bradish and John Means done for the season, Baltimore has deadline pickup Trevor Rogers, Dean Kremer and Albert Suárez as their next three starters behind Burnes.

Rogers struggled for much of the season with the Marlins and has been hit especially hard in four starts since landing in Baltimore. Kremer looks like a fifth starter. Suárez has proven an excellent find in his return to the big leagues after seven years, but he’s probably best suited for a back-end or swing role on a contender. The Orioles will need to land on a fifth starter with Eflin out of action and only one off day between now and September 5. Povich, one of the organization’s top pitching prospects, seems like the choice. He has had a rough opening to his MLB career, allowing a 5.77 ERA with a similarly underwhelming strikeout and walk profile across his first nine starts.
