The Orioles are making another change.

One day after firing manager Brandon Hyde, the club designated veteran starter Kyle Gibson for assignment on Sunday. Gibson, 37, allowed six runs and recorded only two outs on Saturday in the Orioles’ 10-6 loss to the Washington Nationals and had a 16.78 ERA through four starts. He’s a candidate to return to the organization if he clears waivers.

Baltimore recalled right-handed reliever Kade Strowd in a corresponding move..

Gibson joined the Orioles on a one-year, $5.25 million deal at the end of March and ramped up in Norfolk after going unsigned for most of spring training. The right-hander, who started opening day for the Orioles in 2023 and went 15-9 with a 4.73 ERA, had been a solid volume pitcher the past few seasons but struggled to settle in this time around.

“I don’t know that I can attribute anything to that really,” Gibson said Saturday when asked if the quick ramp-up process factored into his results. “I think physically, I feel good. Stuff-wise, frustratingly feels good. Bullpens feel good, everything has been pretty normal. I think these first two or three weeks have been frustrating, to say the least.

“Four times taking the mound feeling like you haven’t given the team a chance to win each time is a pretty big gut punch. Feeling like you’re part of getting a manager fired is a gut punch. Just not going out there and being able to compete and give the team a chance to win every five days is frustrating.”

Gibson’s ERA is the highest in Orioles history for a pitcher with at least four starts in a single season since the franchise moved to Baltimore in 1954.

“Emotions are a real thing,” interim manager Tony Mansolino said. “It’s human beings out there. This is a tough thing. I promise you this: Gibby wanted to go out there and do the complete opposite. It just didn’t work out. It’s a guy we signed late in spring training. He had a quick ramp-up. I know we haven’t seen the best of him yet.”

It remains to be seen how the club will fill his rotation spot. His next turn would’ve been Thursday, but the Orioles appear to be aiming to fill it Tuesday after listing Dean Kremer for Monday’s series opener against the Milwaukee Brewers and pushing Tomoyuki Sugano back a day to have him start Wednesday.

Pitching prospect Chayce McDermott, who pitched as the 27th man in the Orioles’ doubleheader Wednesday, is an option for Tuesday. Charlie Morton, another struggling veteran, threw 62 pitches across 4 2/3 innings in relief of Gibson on Saturday and would be unlikely to start on two days’ rest.

Injury updates: One outfielder is going back on the shelf. The other is hoping to come off it soon.

The Orioles placed Tyler O’Neill back on the 10-day injured list with a left shoulder impingement. It is O’Neill’s second time on the IL this season and the 16th time in his eight-year MLB career. Fellow outfielder Dylan Carlson was recalled to take his place on the roster.

Colton Cowser, however, said he is hoping to go on a minor league rehabilitation assignment “soon” as he makes his way back from a fractured left thumb he suffered in the fourth game of the season. Cowser, the 2024 American League Rookie of the Year runner-up, has been sorely missed as the Orioles have opened the season with a 15-29 record entering Sunday’s matinee against the Washington Nationals.

O’Neill was scratched from Friday’s lineup with the left shoulder injury. Former manager Brandon Hyde said O’Neill suffered the injury in the batting cage earlier this week.

It’s unclear whether the impingement is related to the neck injury that landed O’Neill on the IL in late April. The slugger spent much of the month dealing with the injury that caused him pain to look to his left — a significant impediment as a right-handed hitter.

The 29-year-old opened the season with a 1.079 OPS through his first eight games, but he’s since gone 4-or-51 with a .337 OPS. After missing two weeks with his neck injury, O’Neill returned last week and went 1-for-15 with six strikeouts in 19 plate appearances.

O’Neill’s lengthy injury history was a major factor in his contract from the Orioles being worth only $16.5 million per year over three seasons, despite him being one of the sport’s best power hitters last year.

O’Neill has averaged two IL stints per season in his career, a number he’s already hit through the first seven weeks of this season. Last year with the Red Sox, O’Neill landed on the IL three times. He’s injured 13 body parts in his career.
