A power ranking of the fastest risers
Here’s our Power Rankings of the Top 10 fastest risers in this week’s update of the Top 700 Prospect Rankings. The entire list of the fastest risers, which includes the player’s major-league ETA, number of spots moved up and current new position in the Top 700, can be found HERE (subscription required).
1. Yostin Pena, OF, Yankees — Single-A, Age 18
Pena skipped the complex league entirely after a torrid Dominican Summer League stretch and has been unstoppable at Single-A Tampa ever since, slashing .275/.385/.425 with 9 home runs, 47 RBI, and 34 stolen bases. His exit velocities are eye-popping for an 18-year-old — a 90th-percentile mark around 108 mph and a peak north of 113 — and he’s coming off a two-homer, six-RBI outburst. The swing-and-miss and chase rate need refinement, but this is one of the more electric teenage bats in the minors right now.
2. Adrian Bohorquez, RHP, Twins — High-A, Age 20
A sleeper arm gaining real helium, Bohorquez has seen his fastball tick up to 96-98 mph this year, and both his slider and curveball are generating elite whiff rates. He’s in the middle of a hot stretch marked by a sharply decreased walk rate, which is exactly what evaluators wanted to see translate. He’s shown he can dominate righties consistently; the next step is closing the platoon gap against lefties.
3. Brandon Compton, OF, Marlins — AA, Age 22
Compton has been the hottest bat in the minors over the last month, setting a Double-A Pensacola franchise record with 12 home runs in July alone. Across all levels this season he’s slashing .277/.426/.596 with 30 homers, 18 steals, and a 164 wRC+ — best among all qualified Marlins farmhands. A former two-way college player who had Tommy John surgery before ever throwing a pro pitch, Compton has simplified his approach and is now punishing mistakes at an elite rate.
4. Tony Blanco Jr., 1B, Pirates — High-A, Age 21
The 6-foot-7 son of former big leaguer Tony Blanco has set a new career high with 23 home runs this season for High-A Greensboro, including back-to-back multi-homer games recently. He missed over a month with an injury but has been dominant since returning, batting .333/.422/.859 in the second half. The power is easily plus-plus; the swing-and-miss risk is real, but nobody in the system hits the ball farther.
5. Luis Fragoza, OF, Twins — High-A, Age 19
A relatively under-the-radar 2024 international signee, Fragoza is quietly turning into one of the Twins’ most cost-efficient system additions. He’s climbing our rankings on the strength of a strong all-around performance at High-A this season, and evaluators are increasingly taking notice of a toolset that outkicked his signing bonus.
6. Carter Graham, 1B, Reds — AA, Age 24
Graham has been on a power tear at Double-A, recently posting a multi-homer game as part of a hot stretch that’s forced his way onto more radars. As an older college performer, he doesn’t have the prospect shine of some of the younger names on this list, but the bat-to-ball skill combined with his current power surge make him a name worth knowing in deeper leagues.
7. Nolan Schubart, 1B/OF, Guardians — AA, Age 22
Schubart has 21 home runs this season and once carried a 44-game on-base streak, forcing his way from Single-A up to Double-A. The former undrafted free agent out of Oklahoma State has always had big raw power; the swing-and-miss concerns that keep some evaluators cautious haven’t stopped the production so far.
8. Boston Smith, C, Mariners — AA, Age 22
Acquired from the White Sox in the Luis Castillo trade, Smith has been one of the best offensive performers in the minors since the deal, slashing .291/.447/.603 with 25 home runs and a 1.050 OPS. His 20.7% walk rate is elite for a catcher, and he climbed from Single-A to Double-A in just 92 days. He’s already played for three organizations in his first full pro season — quite the whirlwind for a 2025 sixth-round pick.
9. Lucas Elissalt, RHP, Tigers — AA, Age 21
A 13th-round find out of junior college, Elissalt has added nearly two ticks to his fastball this season, now sitting 93 mph with excellent extension and ride from a low release point. His splitter is a true weapon, playing off the fastball in a way that disrupts hitters’ timing. His last two starts, including his first look at Double-A, produced 15 strikeouts against just six baserunners over 9.2 innings.
10. Welbyn Francisca, SS, Guardians — High-A, Age 20
Cleveland’s $1.375 million international signee continues to hit his stride after an early-season shoulder issue, showing off one of the more surprising power breakouts in the system this year. The bat is currently outpacing the glove at shortstop, but for a switch-hitter who profiles as a hit-tool-first prospect, the power emergence is a real developmental step forward.
