The one thing that the MLB has that a majority of other professional leagues do not are developmental leagues/teams. The MLB also has prospects within each individual organization, something that the NFL doesn't necessarily have. 

For the Baltimore Orioles, spring training serves as an opportunity for their prospects to showcase their skills in hopes to make the opening day roster. 

President of Baseball Operations Mike Elias did a solid job at restocking Baltimore's farm system at the 2025 MLB trade deadline, draft and through international free agency. Fast forward six months, and a boatload of Baltimore's prospects have put together strong starts to spring training. 

Additionally, a handful of proven big leaguers have also put together excellent starts to spring training. 

With that being said, let's dive into the three standalone players who have impressed through the first ten games for Baltimore. 

When Baltimore handed Tyler O'Neill a three-year, $48 million dollar contract in November 2024, they expected him to fill the void of long-time slugger Anthony Santander. Unfortunately for Baltimore (and O'Neill), they did not receive the type of production that was expected from O'Neill in 2025. 

However, O'Neill has looked like a completely different player this spring training. 

Through five games, O'Neill is 7-for-11 (.636) with two extra base hits (one home-run), two walks, and a 1.692 OPS. 

It was only two seasons ago when O'Neill put together a 31 home-run, 61 RBI season for the Boston Red Sox. If Baltimore can get even half of O'Neill spring training production in the regular season, he would be worth every penny and more. 

Coby Mayo, a once top prospect in Baltimore's farm system, has had a roller coaster of a year. After only appearing in 17 games for Baltimore in 2024, Mayo was expected to be an impact player for Baltimore in 2025. Unfortunately for Mayo, his 2025 campaign did not go as expected as in 85 games played he only had a 0.2 WAR with a .687 OPS.

However, Mayo ended his 2025 campaign on a high note, where in 73 at-bats had a slash-line of .301/.393/.548 with five home-runs and eight RBI's in the month of September. Fast forward to spring training and Mayo has picked up right where he left off. 

Mayo has gotten off to a lightning hot start, going 6-for-12 (.500) with two doubles, four RBI's and an OPS of 1.095. 

Mayo could be on the verge of a breakout, especially with starting third baseman Jordan Westburg sidelined until at least mid April with an elbow injury. 

Trevor Rogers was voted the most valuable Oriole in 2025 after his breakout season where he posted a 1.81 ERA in 109.2 innings with a 5.5 WAR. The expectation for Rogers coming into 2026 isn't for him to replicate his 2025 success, however, after a stellar start to spring training, many believe that Rogers is poised for an all-star season. 

Rogers has appeared in only two games so far, but has picked up right where he's left off. In five innings of work, Rogers has yet to give up a run while striking out six and only surrendering two hits. 

Rogers' velocity has remained the same, as he's averaging around 93-94 mph on his fastball with a wicked changeup and slider combination. If Rogers continues to pitch at this high of a level throughout spring training, it would be extremely difficult to not give him the opening day nod. 

Although Baltimore has another handful of players that could've made this list, the production of O'Neill, Mayo and Rogers have been elite to start spring training.
