Tyler O’Neill doesn’t need a reminder of what his splits looked like in 2024. They were as extreme as they have ever been in his career, finding significant success against left-handed pitching while his right-on-right matchups were less eye-popping.

In a way, O’Neill’s numbers against lefties are why he sat Monday in front of a screen, meeting members of Baltimore’s media during his introductory press conference with the Orioles. Baltimore needed a right-handed edge in its outfield to balance out a trio of lefties, and O’Neill — who joined on a three-year, $49.5 million deal — brings that.

But O’Neill sees himself as more than a part-time player, and the contract he signed seems to reinforce the Orioles’ belief in that, too. When O’Neill examines his lone season with the Boston Red Sox, he pinpoints his approach and Fenway Park’s unique configuration as reasons he performed far better against lefties (.313) than righties (.208).

“Part of that was playing at Fenway Park and just being in that home ballpark and really trying to tailor my approach to the left-field wall,” O’Neill said, referring to the 37-foot tall Green Monster. “They wanted me to open up to the pull side and kind of had to play up front a little more, which left me less room for error.”

The approach worked in terms of his power numbers, with 31 home runs and an .847 on-base-plus-slugging percentage. But O’Neill admits that it caused some “streakiness,” and as he looks toward playing home games at Camden Yards for at least 2025 (he has an opt-out after the season), he’s excited about a more neutral playing field.

Of course, Camden Yards hasn’t exactly been a neutral park over the last three seasons.

Early in his discussions with the Orioles, general manager Mike Elias displayed renderings to O’Neill and his agent, Scott Boras, of how Baltimore planned to bring the left-field wall closer to home plate. The Orioles had pushed it deeper and higher in 2022 to address what they felt was an overly disadvantageous environment for pitchers, but Baltimore realized the corrective measure went too far.

Now, with the wall moving between its original and modified dimensions, players such as O’Neill won’t shake their head at near-homers to left field that turn into outs.

“I think if you are a right-handed power-hitter it’s probably something you want to see,” Elias said last week at the winter meetings. “People like hits going over the wall.”

In O’Neill’s case, though, he’s less concerned solely about left field than the overall shape of the outfield. After a season in which he was encouraged to focus on pull-side power — which favors hitting against pitchers of the opposite handedness — O’Neill wants to expand his approach.

“I’m really excited to be able to exploit right-center more,” O’Neill said, “and use the whole field and see what I can post on top of that.”

There was more than the ballpark that attracted O’Neill, of course. He noted how difficult the matchups between the Red Sox and Orioles were last year and he wanted to remain in the competitive American League East.

“There’s a lot of potential with this young core of guys that they have,” O’Neill said. “Winning 91 ballgames last year, hopefully we can add to that this year. I’m very excited to see where it goes.”

To be a critical part of the outfield configuration — sharing time with Cedric Mullins, Colton Cowser and Heston Kjerstad — O’Neill will need to be healthy. That’s another area, along with his splits, that he recognizes hasn’t always been consistent.

In seven major league seasons, O’Neill has been placed on the injured list 14 times. He was injured for three separate stints in 2024.

Some of that is bad luck. But during O’Neill’s offseason training program, he is focused on a balanced program that reinforces his “small muscle groups” and a healthy range of motion.

“I think I don’t neglect small muscle groups that I might have in the past to kind of rush into getting heavy lifts in,” said O’Neill, whose dad was a Canadian body builder. “Because it’s my background and that’s my M.O. and that’s always been my thing, right? Just being a power-hitter and lifting heavy and stuff. So I’ve just had to modify things a little bit. And also making sure I’m giving my body the time to recover, the time that it needs to heal, and make sure that it’s in a good spot to be able to execute those full workouts in the program.”

If O’Neill can remain healthy, and if he improves his splits against right-handed pitching, he could be on track for a strong season in Baltimore that rivals 2021, the pinnacle of his career so far. During that season, when he was with the St. Louis Cardinals, O’Neill hit .286 with a .912 OPS. He also played a career-high 138 games.

He has been chasing that success ever since.

“But last year, I showed that I’m still that player,” O’Neill said. “I still got pop in my bat, I still got speed, I can still play defense and make plays on that side of the ball.”

And in Baltimore, perhaps he can show it again.
