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. Zac Veen, OF, Rockies — MLB, Age 24
Veen was two lost seasons removed from prospect relevance before a complete reset — physically and mentally — turned his 2026 into a career year. He posted a 1.037 OPS with 24 home runs and 18 stolen bases across 100 games at Triple-A Albuquerque, earning a recall to Colorado on August 11 in a corresponding move that saw Edouard Julien designated for assignment. He’s now in the mix for everyday outfield at-bats down the stretch.
2. Eliazar Dishmey, RHP, Marlins — AA, Age 21
Miami’s breakout arm of the summer, Dishmey has thrown a six-inning no-hitter with 10 strikeouts and is running a 0.33 ERA over his last six starts at Double-A Pensacola. What was once a pitch-to-contact profile has become a legitimate swing-and-miss weapon after he added a gyro slider to a plus-fastball-command foundation.
3. Samil Serrano, OF, Nationals — DSL, Age 17
Washington’s headline 2026 international signing at $1.97 million, Serrano is a lean, projectable lefty bat with a fluid, loose swing that scouts have already flagged as one of the better hit tools in his international class. He’s off to a hot start in the Dominican Summer League and is exactly the kind of teenage riser worth stashing early in deep dynasty and international-prospect formats.
4. Pablo Guerrero, 1B, Rangers — Single-A, Age 19
The younger brother of Vladimir Guerrero Jr. and son of Hall of Famer Vladimir Guerrero, Pablo has plus raw power in his own right and was an above-average hitter in the Texas League as a teenager last year. He missed most of 2026 recovering from UCL surgery, and this week’s jump reflects his long-awaited return to the field — the power/hit combination is very real when he’s on the diamond.
5. Angel Genao, SS, Guardians — MLB, Age 22
Genao made his major-league debut on August 5 against the Mets after hitting .299/.400/.458 with 11 home runs and 11 steals across Double-A and Triple-A this season. Cleveland is clinging to a wild-card spot, and Genao’s switch-hitting, disciplined approach (a 14.3% walk rate against just a 16% strikeout rate in the minors) gives him a real shot at everyday at-bats immediately.
6. Charles McAdoo, 2B/3B/1B, Blue Jays — MLB, Age 24
A 13th-round afterthought when Pittsburgh drafted him in 2023, McAdoo has forced his way onto Toronto’s roster with defensive versatility and legitimate pop, homering off Sonny Gray in his return from a brief demotion. He hit .250/.356/.436 with eight homers at Triple-A Buffalo before the call-up and offers corner-infield thump in a Blue Jays lineup that’s needed a spark.
7. Brailyn Antunez, OF, Brewers — Single-A, Age 18
Milwaukee’s $900,000 international signee from Chourio’s hometown of Maracaibo, Venezuela struggled in his pro debut last year but has flipped the switch stateside — an 8-for-18 week with a homer and 8 RBI, followed immediately by a 9-for-24, three-homer week that pushed his early Single-A OPS above 1.300. Plus-plus speed and a developing power tool make him one of the system’s most exciting long-term watches.
8. Caden Hunter, SP, Orioles — AA, Age 22
A sixth-round pick out of USC in 2025, Hunter has been one of the best pitchers in the minors this year, running a 1.32 ERA with 112 strikeouts in 75 innings across three levels. He carried a no-hit bid into the seventh inning of his Double-A debut, striking out 10 with a 90-97 mph fastball and a sweeping slider — Baltimore may have found another under-the-radar arm to add to its pitching pipeline.
9. Joseph Dzierwa, SP, Orioles — AA, Age 22
Hunter’s rotation-mate in Baltimore’s system, the 6-foot-8 Dzierwa has been every bit as dominant, earning an invite to the 2026 MLB Futures Game off a 40.2-inning stretch with 50 strikeouts and a 2.21 ERA at High-A before a seamless transition to Double-A. He’s issued multiple walks in a start just four times all year — the command profile of a future rotation piece.
10. Welbyn Francisca, SS, Guardians — High-A, Age 20
Cleveland’s $1.375 million international signee from 2023 missed the start of the season with a shoulder issue, but since returning he’s turned into one of the hottest bats in the minors — 13 home runs in 44 High-A games, including eight over his last 14 contests. The bat is clearly ahead of the glove at shortstop right now, but the power breakout is a real development for a switch-hitter who profiles as a hit-tool-first prospect.
