As the year comes to a close, it's a good time to look ahead to the 2025 season.

A number of interesting prospects are expected to make their full-season debuts this spring, a mix of recent draftees who did not play after signing and international signees ready to break out of Rookie ball.

In 2024, Rhett Lowder and Chase Dollander established themselves as two of baseball's best pitching prospects in their first professional seasons, with Lowder moving from High-A to the Majors. Fellow 2023 draftees Brandon Sproat, Quinn Mathews and Alejandro Rosario cemented their places on the Top 100 Prospects list, while 17-year-old phenom Leodalis De Vries made a splash at Single-A.

There are currently six Top 100 prospects who have yet to make their full-season debuts and several more players ready to reach Single-A who could soon crack the list. Here are the players to know:

Chase Burns, RHP, Reds (CIN No. 1/MLB No. 21)
After selecting Lowder sixth overall in 2023 out of Wake Forest, Cincinnati went back for seconds and drafted fellow Demon Deacon Burns second overall in '24. Burns got the same treatment of not pitching the rest of the year after signing, so could he take a similar leap to the Majors in 2025? That's probably a long shot, but Burns has the stuff to dominate in the upper Minors for most of his debut campaign.

Konnor Griffin, SS/OF, Pirates (PIT No. 2/MLB No. 50)
The first high schooler selected in the 2024 Draft, Griffin is a tremendous athlete with perhaps the highest ceiling in his class. The Pirates plan to start the Mississippi native, who was named Gatorade National High School Player of the Year, at shortstop, although it will be interesting to see if the club gives him time in center field, where his plus speed and arm would play well.

Braden Montgomery, OF, White Sox (CWS No. 5/MLB No. 54)
Montgomery never got a chance to play as a member of the Red Sox, who selected him 12th overall last July, in part because he broke his ankle during the NCAA Super Regionals. Part of Chicago's return for Garrett Crochet, the switch-hitting outfielder will instead make his pro debut in the White Sox organization. Montgomery's well-rounded tool set -- highlighted by plus power and arm strength -- could allow him to move quickly through the Minors.

Bryce Rainer, SS, Tigers (DET No. 4/MLB No. 56)
Rainer produced the largest exit velocities at the National High School Invitational last spring and is ready to take his loud tools to pro ball after Detroit selected him 11th overall. The California native was a two-way player in high school and has a chance to take off as he focuses on hitting.

Felnin Celesten, SS, Mariners (SEA No. 5/MLB No. 66)
Celesten has received plenty of hype as the No. 2 international prospect in the 2023 class behind only Ethan Salas. He might have reached Single-A in 2024 if not for a season-ending hamate injury in July that required surgery. The switch-hitting shortstop should be able to finally put his lofty potential on display in full-season ball in his age-19 season.

Trey Yesavage, RHP, Blue Jays (TOR No. 1/MLB No. 94)
After Yesavage tossed 93 1/3 innings at East Carolina last spring, Toronto didn't mind having its first-round pick sit out the rest of 2024. Yesavage will have the chance to show off his four-pitch mix this spring, and it will be important to see if the improved command that keyed his rise in 2024 sticks in '25.

Jesus Made, SS/3B, Brewers (MIL No. 4)
Hyped as the No. 23 international prospect in the 2024 class, Made has already exceeded expectations by putting up MLB-caliber exit velocities and showing excellent discipline (including more walks than strikeouts) in the Rookie-level Dominican Summer League. The infielder will be on the Top 100 sooner rather than later. Since Milwaukee is known for being aggressive with assignments, he is worth closely monitoring. (So is Luis Pena, who put up even better numbers.)

Brailer Guerrero, OF, Rays (TB No. 6)
Guerrero shows prodigious power from the left side that helped him earn $3.7 million as the No. 12 prospect in the 2023 international class. A pair of injuries cut short his first two Minor League campaigns, so a healthy season in 2025 will be as important as anything as he is challenged at Single-A.

Joendry Vargas, SS, Dodgers (LAD No. 7)
Formerly a switch-hitter, Vargas, ranked third in the 2023 international class, only swings from the right side now, where he displays above-average potential for average and power. At 6-foot-4, he may eventually have to shift to third base, but he has the range and quickness to stick at shortstop for now.

Emil Morales, SS, Dodgers (LAD No. 8)
The Dodgers seemingly struck gold again with Morales, their top signing in the 2024 class, who like Vargas is a large-framed shortstop with big offensive potential. He'll likely head to the Rookie-level Arizona Complex League before reaching Single-A, but his advanced approach should allow him to hold up against older competition.

Jeremy Rodriguez, SS/2B, Mets (NYM No. 7)
Rodriguez has an unusually high floor for a Rookie-ball player thanks to his defensive instincts, plate discipline and bat-to-ball skills. The Mets have played him some at second base so his defensive home is worth monitoring as well as his power, which has mostly manifested in the form of doubles to this point.

Jurrangelo Cijntje, RHP/LHP, Mariners (SEA No. 7)
There is perhaps no prospect more intriguing than Cijntje, a rare ambidextrous pitcher. The 15th overall selection last July is better from the right side than from his natural left and even pitched right-handed to some lefties last year at Mississippi State. The Mariners have committed for now to letting him pitch from both sides, which could make him quite a weapon.

Ryan Sloan, RHP, Mariners (SEA No. 8)
Sloan was the highest-ranked high school righty in the 2024 Draft and earned an above-slot $3 million bonus from the Mariners. He has top-of-the-rotation upside between his 6-foot-5 size, unusual polish for a prep pitcher and the potential for three plus pitches, so how he adjusts from Illinois high school ball to Single-A could enable him to rise in the rankings in the same fashion as 2023 prep righty Travis Sykora.

Slade Caldwell, OF, D-backs (AZ No. 3)
The D-backs haven't been afraid to develop undersized, speedy outfielders in the past, and Caldwell could be their next star after going 29th overall in July. Arkansas' two-time Gatorade Player of the Year has a compact swing with promising bat speed that could result in some big on-base numbers in the California League.

Kellon Lindsey, SS, Dodgers (LAD No. 10)
Lindsey is tooled up with top-of-the-line speed and the impressive athleticism you'd expect from a dual-threat high school quarterback. He's put on weight since the Dodgers drafted him 23rd overall, so it will be interesting to see if that translates into impact power now that he's focused on one sport.

Kash Mayfield, LHP, Padres (SD No. 3)
Teams didn't have much data on the prep lefty heading into the 2024 Draft since he didn't pitch in any major showcase events, but Mayfield's strong spring cemented his place as a first-round Draft prospect thanks to increased velocity and his long-established strike-throwing ability. The Oklahoma native's first foray into pro ball will paint an even better picture, with tangible pitch data to go along with how he fares against stronger competition.

Rayner Arias, OF, Giants (SF No. 5)
Arias earned the second-largest bonus in Giants history as the No. 15 international prospect in the 2023 class thanks to his impressive right-handed power. The Dominican native has an advanced approach and high baseball IQ, thanks in part to his father playing in the upper Minors. The bigger questions as he makes his full-season debut are whether he can stay healthy and remain quick enough to stick in center field.

Brody Brecht, RHP, Rockies (COL No. 6)
Brecht had some of the best stuff in the 2024 Draft with a double-plus fastball and slider, although his control issues led to 135 walks across 178 innings in three seasons at Iowa. The Rockies got the most out of Dollander last year after resting him at the end of 2023, so it will be fascinating to see how they can develop their latest high-ceiling college pitcher.
