Rookies, prospects, and camp risers who are making real noise right now (as of Feb 28, 2026).
Spring training can lie to you, but it does not lie equally. When a young player is getting meaningful looks in big league games, running with veterans, or showing a new level of bat speed or velocity, teams notice. So do sharp collectors.
Below is a player-first rundown compiled from recent spring training reporting and roster-bubble coverage published in the last few days.
The “they might force the issue” hitters
Michael Arroyo, Mariners (2B)
Arroyo came into camp with buzz, and he has played like he wants to skip the waiting room. MLB Pipeline noted he homered in his first Cactus League at-bat on a tough count and, more importantly, showed loud contact quality right away. That is the type of early “this looks different” signal that can change a timeline fast.
Josh Kasevich, Blue Jays (INF)
Kasevich is the exact profile that can win a job quietly if the bat shows real impact. MLB Pipeline called out a 103 mph homer that was not a cheap one, after an injury-interrupted stretch raised questions about his power. If the extra-base thump is back, Toronto suddenly has a real, near-ready infield option.
Ryan Waldschmidt, Diamondbacks (OF)
If you want a “not famous yet, but could matter sooner than people think” name, Waldschmidt fits. CBS noted he produced across High-A and Double-A last year with strong on-base ability and power, and flagged the Diamondbacks outfield situation as a reason to watch his spring closely.
Leo De Vries, Athletics (SS)
De Vries is the kind of young talent that becomes appointment viewing. CBS described him as a top-end prospect who reached Double-A as an 18-year-old and suggested the club may not carry him on Opening Day, but also that a big-league debut at 19 later this year is firmly in play. In card terms, this is the type of name that can heat up quickly once highlights start circulating.
J.J. Wetherholt, Cardinals (INF)
Roster context matters, and CBS pointed out that potential infield movement opens a lane for Wetherholt to spend real time in the majors in 2026. He has the kind of skill set that plays on a competitive team: on-base ability, speed, and defensive value.
Colt Emerson, Mariners (INF)
Emerson is another “watch the opportunity” player. CBS noted Seattle has an infield opening and that the organization has indicated Emerson will be given a chance to win it despite minimal Triple-A time. When a team tells you a prospect is getting a real shot, listen.
The arms that have scouts leaning forward
Carlos Lagrange, Yankees (RHP)
If you care about pure stuff, Lagrange has been impossible to ignore. MLB Pipeline noted he has been among the hardest throwers in spring, including triple-digit readings and multiple pitches over 101 mph, plus signs of whiffs with secondaries. He is still developing, but this is exactly how a bullpen weapon announces itself.
Bishop Letson, Brewers (RHP)
Velocity jumps are one of the few spring signals that translate cleanly. MLB Pipeline reported Letson’s fastball was up into the upper 90s in an outing after sitting lower last year while pitching through a shoulder issue, with carry and spin that make hitters uncomfortable. That kind of step forward can move a pitcher into a much more serious conversation.
Logan Henderson, Brewers (RHP)
This one is more subtle but still meaningful. MLB Pipeline highlighted Henderson experimenting with a curveball in spring after barely using it previously, which matters because young pitchers stick when they are less predictable. If he finds a real third look, it changes the profile.
Luis De León, Orioles (LHP)
If you want an upside arm with real ingredients, De León is one to file away. CBS described him as having high-end raw stuff, including upper-90s velocity from the left side and secondaries that miss bats, with the usual young-pitcher control caveats.
JR Ritchie, Braves (RHP)
CBS framed Ritchie as a near lock to make starts for Atlanta at some point in 2026 based on his workload, results, and arsenal depth. That is not a prediction you see tossed around lightly for a young arm on a contender.
Camp and roster context names worth tracking now
A lot of the best “early-season surprises” are not the No. 1 prospect in a system. They are the player who can fill a need right now.
Mikey Romero, Red Sox (INF)
MLB.com’s dark-horse roster piece flagged Romero as a real camp factor, with the team noting improved health and physicality, plus power production in the upper minors. That is how a depth chart gets disrupted.
CJ Stanifer, Blue Jays (RHP)
CBS highlighted Stanifer because he may be closer to contributing than the flashier names. Strikeout ability plays, especially if a team needs innings and leverage options over a long season.
Andrew Painter, Phillies (RHP) and Emmanuel Rodriguez, Twins (OF)
CBS explicitly called out that some top prospects are already in big-league camp because they are on the 40-man roster, naming Painter and Rodriguez as examples. These are the types of players who can flip from “prospect” to “everyday conversation” quickly once the club signals a real role.
