Athletics

Riser to know:Bolte and Kuroda-Grauer

Bolte is another player who made one of those great swing changes in which he improves his weakness (contact and chase outside of the zone) without losing any of what already made him a prospect (raw power) and, if anything, also made him better in that area (almost reaching a career high for homers in 37 minor league games before his big league debut). Kuroda-Grauer also added a notch or two of in-game loft along with a notch or two of raw power.

Arizona Diamondbacks

Riser to know: Dix

Dix is a 6-foot-2, switch-hitting middle infielder with high walk rates and plus speed, but he didn't show much power last year, with two homers in 89 games. He has added loft to his swing but not that much more raw power -- though that has been enough to spike his homer total to nine in only 38 games this season.

Atlanta Braves

Riser to know: Hartman

Hartman lost the coin flip for the 10th spot last month because I wanted to see more to be sure his breakout was for real, as he'd played only 20 games at that point. Since he was left off the May top 10, he has hit .299/.386/..539 with five home runs and nine stolen bases in 25 games. It looks real now.

Baltimore Orioles

Riser to know:Aloy

I ranked Aloy 15th in my final 2025 draft rankings, but he then went 31st in last summer's draft and I heard from scouts that they worried his contact issues would get much worse in pro ball. I moved him down a bit to reflect that, but one year later, he's hitting the ball harder than he did with aluminum bats last year at Arkansas, on basically the same homer pace, and all with a strikeout rate just 4.5 percentage points more than he had in the SEC. Double-A will be a test, but Aloy has passed the tests he has faced so far. Dzierwa, Bateman, Quinn and Anderson all also qualify as risers.

Boston Red Sox

Riser to know:Azocar

Azocar's raw power and in-game loft are both up this year, adding to his above-average speed and potential to stick in center field long term. Gonzales has also added more loft this year and Godbout has also (wait for it) added some power and loft to his profile. Arias and Eyanson were the two big arrow-ups in last month's update (Valera's recent Tommy John surgery was a downer) and now there are three more.

Chicago Cubs

Riser to know:Hartshorn

I was high on Hartshorn in last year's draft, ranking him 50th on my final draft rankings, so I was surprised when he lasted until the sixth round, even though he signed for second-round money at $2 million. I did not see him putting up a .431 OBP with more walks than strikeouts and a promotion to High-A a few months after he turned 19. I was also high on Wing in that draft class and he's one velo bump away from soaring up this list.

Chicago White Sox

Riser to know: Gonzalez

Gonzalez has changed his setup to be more upright and allow him to swing harder, which has manifested in his exit velocities: His peak EV went from 109 to 114 mph and his 90th-percentile EV went from 102 to 105 mph. That's something like fringy power to at least plus power with that adjustment. Gonzalez is a left-handed-hitting infielder who still has above-average bat-to-ball skills and plus in-game power with more lift to get to it in games, but chases more than he did before. He just got called up after Munetaka Murakami's injury, and I'll be fascinated to see how this new swing fares in the big leagues after Gonzalez torched Triple-A with 19 homers in 52 games.

Cincinnati Reds

Riser to know:Arroyo

Arroyo was acquired from Seattle during the 2022 season and sat out the 2024 season because of shoulder surgery. He hit 13 homers in his return last season, but the power is really back in his game now -- he has hit 11 homers this season through 53 games. Arroyo is showing more in-game loft and more raw power; he might be a big league option in the second half.

Cleveland Guardians

Riser to know:Curley

Curley received some attention around this time last season for his defensive miscues for Tennessee, but that distracted from his early-round draft upside as an infielder. His walk rate has spiked this season and he's hitting for enough power to profile anywhere on the field, though he's mostly playing shortstop.

Colorado Rockies

Riser to know:Hughes

Hughes improved the shape of his cutter and is throwing it harder than last year, and he's performing much better in Triple-A than he did last year, now two years removed from elbow surgery. His 91-94 mph cutter is his primary fastball, which works well with his sinker and sweeper going in opposite directions from that starting point. He could be a big league option later this season.

Detroit Tigers

Riser to know:Yost and Witherspoon

Two of Detroit's early picks in the 2025 draft are looking a bit better than I expected they would at draft time.

Yost was a spring pop-up prospect who didn't play in any of the big summer events, so despite his tools, there was basically no evidence that he could hit pro-level arms. He was solid in a short look in major league spring training and has gotten on base at a strong clip (.386 so far) in 23 Single-A games. The power isn't there yet, but there's some projection in his frame and plenty of time. Witherspoon has slightly better numbers than college thus far, as well as solid stuff, so avoiding hard contact should see his current high ERA fall soon.

Houston Astros

Riser to know: Alvarez

Neyens and Alvarez are both big, young left-handed hitters with power potential, but Neyens' comes with lots of swing-and-miss and Alvarez has less plus more power on the way. Alvarez has time for that to come, as he's still the age of the high school players in the 2026 draft and is hitting well in Single-A. Similar to Dodgers outfielder Josue De Paula, if Alvarez can add more loft to his swing, he could be high on the top 100 in short order.

Kansas City Royals

Riser to know:Lamkin

I preferred Lombardi in last year's draft because of his athleticism and edge in raw stuff, but Lamkin went 10 picks later for a comparable bonus and now has the edge. The 6-foot-4 lefty is already in Double-A with a big strikeout rate because he knows how to attack hitters with his mostly average raw stuff.

Los Angeles Angels

Riser to know:Jordan

I liked Jordan on the summer showcase circuit for his Aaron Nola-type vibes, but he slid a bit in the draft since his low-90s velocity didn't progress much in his high school senior spring of 2024, eventually signing for $1.25 million in the fifth round. He's now sitting between 92-96 and hitting 97 mph, which has helped his sweeper and changeup play up even more and caused his strikeout rate to spike.

Los Angeles Dodgers

Riser to know:Harlan

Harlan was a toolsy, young-for-the-class prep prospect in the 2024 draft and has posted big exit velos and homer totals since turning pro. He's now hitting for average (.325 as of publication, underlying stats to match) along with that same power (seven homers, .221 isolated power through 41 games) and exit velos to show that isn't an aberration (max EV of 116 mph as a 19-year-old).

Miami Marlins

Riser to know:Milbrandt

I mentioned Milbrandt as a riser in my recent midseason top 50 update because his stuff continues to improve and now his command is at a point where you can consider him sticking in a rotation long term. He's sitting 94-97 mph with above-average shape and an above-average bullet slider and sweeper as his main off-speed pitches.

Milwaukee Brewers

Riser to know:Lara

There are a number of hitters you could justify for the backend of the top 10 who didn't make it but are basically coinflips with the players who did: Brady Ebel, Andrew Fischer, Blake Burke and Marco Dinges. I moved the lower minors- and corner-types to the bottom of this group, but almost any of them would be in contention for the top 150-or-so prospects in baseball. Lara floated to the top because he's a plus defender in center field and his exit velo and in-game loft both improved, spiking his isolated slugging by about 80 points.

Minnesota Twins

Riser to know:Quick and Mendez

Quick is a former offensive tackle prospect who made a jump last year at Alabama with bigger stuff after elbow surgery, but his command wasn't where it needed to be. His strikeout rate is up from college and his walk rate is around the same. Quick has plus velo on his sinker along with an above-average cutter and sweeper, and a changeup he doesn't use much. There's more to come.

Mendez was acquired in the Harrison Bader trade from the Phillies at last year's deadline and is having a career year in almost every offensive category, punctuated by a promotion to Triple-A. There isn't much speed or defensive value and he still needs to lift the ball more, but there's a solid big leaguer here -- and maybe soon.

New York Mets

Riser to know: Ewing

I was bullish on Ewing since the second half of 2025 and temporarily had him above fellow Mets outfielder Carson Benge (who graduated from this list), but settled on the two being pretty closely ranked within the same tier over the winter. If Ewing can add more loft to his swing, he could be a star, but he has a solid floor as a low-end everyday player.

New York Yankees

Riser to know: Linan

Linan was acquired for Jorbit Vivas in March and isn't a traditional top-of-the-prospect-list-type as a 6-foot righty who sits 88-92 mph with two below-average breaking pitches. He's performing this well (51 strikeouts to 12 walks) because of his 75-79 mph plus-plus changeup that has a 57% swing-and-miss rate and a 67% groundball rate, thrown at the bottom of the strike zone. The challenge will be in fine-tuning his other pitches to continue setting hitters up at higher levels of the minors.

Philadelphia Phillies

Riser to know:Wood

Wood was a personal favorite last spring in the draft and fell to the 26th pick mostly due to questions about his long-term durability. He has been dealing this season and is now in Double-A with gaudy numbers (50 strikeouts to 13 walks), averaging a little over three innings per outing. There's at least a late-inning reliever here, and there could be a frontline starter if it all clicks.

Pittsburgh Pirates

Riser to know:Gray

Gray is one of the under-the-radar arrow-up prospects from the 2025 draft, after the Pirates took him with the No. 73 pick. With 13 homers through 48 pro games, he has almost matched his homer total from last spring at Fresno State -- and he has also posted a .424 on-base percentage along the way. There's a shot that Gray is a right/right first baseman in the long term, so he'll need to mash. I'd like to see him finish the season in Double-A, but he looks like a nice find for Pittsburgh.

San Diego Padres

Riser to know:Balzer

Balzer has an interesting background, signing with the Padres for $10,000 as a Japanese high schooler. There's some reliever risk and he's only 6-foot-1, but he has lively raw stuff, sitting 94-97 and hitting 100 mph along with an 83-86 mph sweeper. He dropped his walk rate from 12% last year to 8% this year, which is really encouraging, and the Padres are never shy about promoting prospects who are impressing.

San Francisco Giants

Riser to know: Harber

Harber was an undrafted free agent in 2024, when he was almost 23. He had a huge 2025, was included in the Camilo Doval trade, and now is 24 years old in Double-A and still mashing. He had a .928 career OPS in college at Georgia and North Carolina and now has a career .942 OPS in the minor leagues. Try as you might, you can't predict baseball.

Seattle Mariners

Riser to know:Montes

No one new breaks into the list, so there isn't a huge mover -- but Montes is worth noting. His profile is a polished power hitter with enough contact/on-base skills but not a ton of speed/defensive value, so he has to prove he's going to mash at every level to have real big league value. He now has 26 Double-A homers across parts of two seasons and is 21 years old. It's time to move him to Triple-A soon, as it's also his Rule 5 protection year.

St. Louis Cardinals

Riser to know:Fajardo

I've already written a good bit about Franklin being one of the finds of the 2025 draft, so I'll move on to Fajardo. He already has been traded twice, from the White Sox to the Red Sox and now to the Cardinals in the Willson Contreras deal over the winter. He's still just 19 years old but is now dealing in High-A as a starter after performing well at every stop of the minors.

Fajardo is sitting 93-96 mph and has a solid-average slider and above-average changeup to go with his starter-level command. Some other arms just off of this top 10 have more currency with Cardinals fans because of how long they've been prospects, but it might be time to shift your focus to Doyle, Franklin, Cijntje and Fajardo, all acquired in the past year.

Tampa Bay Rays

Riser to know:Flewelling

Last month, I mentioned Flewelling and Flemming as losing the coin flips to make the top 10 but to keep an eye on them. Well, they bullied their way onto the list this month, pushing off a first-round pick from last year in ourfielder Slater de Brun -- and Flewelling almost jumped to the top.

His exit velos have improved only a smidge, but he's making more in-zone contact, has more loft in his swing, and is making contact out front more often. Essentially, he learned how to tap into his power. Gray is also worth noting and has been so good in a short look at Single-A that I put him in over de Brun, who has yet to play a pro game.

Texas Rangers

Riser to know:Castillo

Castillo's power hasn't taken the big jump some hoped for just yet, but he has physical projection left. After a 28-game stint in Single-A last year, the 19-year-old returned there to start this season, was better across the board and got the promotion to High-A. If the power comes, he'll move onto the top 100.

Toronto Blue Jays

Riser to know:Keys

He seems in line for a promotion to Triple-A with his high-level production at Double-A: .404 on-base, .535 slugging and 11 homers in 45 games. Keys was a pick-to-click that I placed high in the winter in anticipation of a breakout, but I didn't think he'd add 70 points of isolated slugging. That said, he did add 4 mph to both his 90th percentile and max exit velos, so that will make the job a bit easier.

Washington Nationals

Riser to know:King

The system is largely arrow-up as a whole in the first year of the new regime. King corrected a swing flaw in the Arizona Fall League that both added raw power and loft, but also improved his contact and chase rates. He's now raking in Triple-A and might be a big league option later this year or early in 2027. Fitz-Gerald was acquired in the MacKenzie Gore deal, and though he isn't that big, he has solid raw power and lots of secondary skills: pitch selection and pull/lift to tap into that power. He's doing both in a big way right now.

I had the Nationals with a group of 13 players and basically cut the last three because of their position, but they're still worth a mention and you could argue they should be in the top 10: right-hander Miguel Sime (sits 97-101 mph), right-hander Landon Harmon and first baseman/outfielder Ethan Petry.
