As we roll out our latest update to the RotoProspects Top 700 Prospect fantasy baseball rankings, let’s dive into the key updates surrounding the top-ranked prospects this week.

Phillies third baseman Aidan Miller jumps into the Top 25 after his stellar 2025 season

Entering the 2025 season as one of Philadelphia’s highest-profile hitting prospects, Miller delivered a breakthrough year highlighted by a strong offensive finish that culminated in a promotion to Triple-A Lehigh Valley late in the campaign. Across 108 games at Double-A and brief stints in Triple-A, Miller posted approximately a .259/.368/.442 slash line, with 13 home runs, 105 hits, and 52 stolen bases, showcasing a dynamic combination of contact ability and baserunning impact. His performance surged in August and September, including a stretch with over a .350 batting average and an OPS above .990 that convinced the Phillies to elevate him for the season’s close. Scouts lauded his improved approach and discipline, with his walk totals often outpacing strikeouts during his hottest stretches. Miller’s advanced plate discipline and defensive improvements suggest a mid-2026 MLB ETA and keep him firmly in discussion as one of the game’s rising all-around offensive talents.

Mariners shortstop Colt Emerson rises to No. 30, could compete for a job in spring training

Emerson (pictured above) maintained his status as an elite young talent throughout 2025, demonstrating the combination of bat-to-ball skills, solid exit velocities, and defensive polish that merited a high organizational ranking entering the season. Emerson’s performance in High-A and later at Double-A featured consistent contact and flashes of power, including multiple multi-hit and extra-base games against top pitching in the upper minors. Notably, Emerson starred in multiple standout games in September, illustrating his ability to rise to the occasion and impact games in multiple ways. Emerson’s expected to enter camp with the chance to win the third-base job.

Joshua Baez earns a spot on Cardinals’ 40-man roster, jumps inside the Top 30

Baez’s 2025 season marked a significant performance jump as one of the Cardinals’ most dynamic position-player prospects. Across High-A Peoria and Double-A Springfield, Baez finished with approximately .287 batting average, 20 home runs, 79 RBIs, 54 stolen bases, and an .884 OPS — power and speed that don’t frequently coexist at his age and level. His improved strikeout rate (down to roughly 20.6 percent) helped sustain ball-in-play success, and his ability to produce across the lineup and take extra bases consistently earned him a spot on St. Louis’ 40-man roster following the season. Baez’s balanced offensive profile — plus a mix of power and baserunning — positions him as a 2026 breakout candidate and red-hot trade piece for a team seeking impact from an emerging outfielder.

White Sox SS/3B Caleb Bonemer rises into the Top 75 after impressive pro debut

Bonemer continued to build momentum throughout his first full professional season in 2025, ending the year as one of the most exciting young bats in the White Sox system. Across 107 games between Low-A Kannapolis and High-A Winston-Salem, he slashed .281/.401/.473 with 12 home runs, 64 RBIs, and 29 stolen bases, showcasing both power and speed at age 19. He walked at an aggressive pace (high double-digit walk rate) and combined that with solid contact ability — which points to above-average on-base skills and run creation. Bonemer was featured among the top High-A hitters based on wRC+ and exit-velocity profiles. With multi-position defensive flexibility and impact offense at a young age, he is trending toward a significant jump in 2026.

Rockies 2B/OF Roldy Brito impresses with a .960 OPS in his first season stateside

Brito’s 2025 season marked a continuation of his promising early career trajectory, combining above-average bat-to-ball skills with emerging power and excellent contact rates. Over 84 games between the Arizona Complex League and Low-A Fresno, Brito slashed .371/.444/.516 with 4 home runs, 38 RBIs, and 35 stolen bases, showcasing a rare blend of extra-base potential and speed at age 18. His combination of hit tool, plate discipline, and speed has made him one of the Rockies’ more intriguing international signees. While he remains early in his pro timeline, the underlying metrics and multi-tool profile make him one to watch as he progresses through full-season ball in 2026.

Japanese free agents bringing their talents to MLB, with all three debuting inside the Top 100

* Astros RHP Tatsuya Imai debuts at No. 43: Imai’s 2025 campaign in Nippon Professional Baseball solidified him as one of Japan’s premier pitching talents. With the Seibu Lions, Imai amassed a 1.92 ERA over 163+ innings, striking out 178 and anchoring one of the Pacific League’s best rotations. He also featured in a combined no-hitter and posted career-best strikeout totals, drawing interest from MLB clubs during the offseason posting window. The Astros signed him to a 3-year, $54M contract with opt-outs after each season. His polished repertoire and durability make him a compelling 2026 option.

* White Sox 1B/3B Munetaka Murakami debuts at No. 44: Murakami, one of Japan’s most feared offensive players, posted a strong — albeit injury-shortened — 2025 season before joining the White Sox on a two-year contract. Across 65 games with the Tokyo Yakult Swallows, he slashed roughly .273/.379/.663 with 22 home runs and 47 RBIs, continuing a track record of power production that includes multiple 30+ home run seasons and a historic 2022 campaign. While defensive limitations and high strikeout rates tempered MLB market valuations, his run production and elite slugging ability give the White Sox a middle-of-the-order bat capable of impact at first base or DH in 2026.

* Blue Jays 1B/3B Kazuma Okamoto debuts at No. 86: Long recognized as one of Japan’s premier run producers, Okamoto signed a multi-year deal with Toronto this offseason. His 2025 NPB season was noted for consistency and strong offensive performance, despite elbow injury limitations. Over 69 games, Okamoto demonstrated elite contact skills and power, contributing to an overall .327/.416/.598 performance and reinforcing his reputation as a high-impact hitter. His transition to MLB as a veteran slugger aligns with Toronto’s championship aspirations and provides a potent bat to complement an evolving lineup in 2026.

JJ Wetherholt, SS, Cardinals: MVP-caliber 2025 and early MLB impact potential

Wetherholt (pictured above) had a breakout season in 2025, cementing himself as one of baseball’s elite young bats and a strong contender to factor into 2026 Rookie of the Year discussions. Across Double-A Springfield and Triple-A Memphis, he slashed .306/.421/.510 with a .931 OPS, contributing 17 home runs, 59 RBIs, and 23 stolen bases in 109 games while showing excellent on-base skills and speed. He also earned organizational and league honors, being named the Cardinals’ Minor League Player of the Year and the Texas League MVP — rare distinctions for a player his age.

Wetherholt’s 2025 performance combined mature plate discipline with power growth — the kind of balanced profile that has evaluators projecting him toward a significant role in St. Louis in 2026. With versatility shown across the infield and already excelling at Triple-A, he is poised to push for an Opening Day roster spot and could rack up counting stats early in his big-league tenure. Recent coverage suggests he’s expected to play a key offensive role for the Cardinals in 2026, and if he delivers anywhere near his minor-league production at the MLB level, a Rookie of the Year campaign isn’t out of the question.

Kevin McGonigle, 2B/SS, Tigers: Elite contact, AFL MVP, and 2026 ROY upside

McGonigle put together one of the most analytically impressive offensive seasons among all 2025 minor leaguers, making him another strong candidate for a 2026 Rookie of the Year push. Though his season was shortened due to injury, he slashed .305/.408/.583 with 19 home runs, 80 RBIs, and outstanding plate discipline, evidenced by a 182 wRC+ — the highest among over 1,000 qualified minor leaguers.

McGonigle capped his campaign with a standout showing in the Arizona Fall League, where he was named AFL MVP after slashing .362/.500/.710 over 88 plate appearances, showcasing both power and on-base ability against high-end pitching. Even in a crowded Tigers infield picture, Detroit’s offseason planning indicates he’s firmly in the mix for a 2026 big-league opportunity, with flexibility to play multiple infield spots and advanced metrics validating his offensive profile. If he earns regular playing time and replicates his minor-league production at the MLB level, his combination of run creation and power could well put him in the Rookie of the Year conversation.

As we roll out our latest update to the RotoProspects Top 700 Prospect fantasy baseball rankings, let’s dive into the key updates surrounding the top-ranked prospects this week.

Dodgers pitcher Roki Sasaki jumps into the Top 50

Sasaki’s postseason explosion has forced a major uptick in his ranking, now cracking into the Top 50 overall. After a 2025 regular season that featured a 4.46 ERA over 36.1 innings with 28 strikeouts and a 1.43 WHIP. His true breakout came in October: shifted from starter to relief, he famously recorded his first-career saves in the postseason, becoming the first pitcher to record the first two saves of his career in the postseason. In high-leverage games he thrived— posting a sub-1.00 ERA and repeatedly delivering when it mattered most. His fastball readings ramped up (99–101 mph), and his strikeout rate surged. With that dynamism and upside profile (70fb-55sl-70sp-65fv), he now demands serious attention and naturally slips into the Top 50 category.

White Sox pitcher Hagen Smith climbs into the Top 75

Smith earns a substantial bump thanks to his strong showing in the Arizona Fall League (AFL). In five starts he logged 14 innings with a 2.57 ERA, 21 strikeouts, seven hits and six walks. He also was selected for the AFL Fall Stars Game—further evidence of the upward revision of his stock. His 2025 full-season numbers in Double-A included a 3.57 ERA over 75⅔ innings with 108 strikeouts and 42 hits allowed. Given his left-handed profile, premium strikeout ability, and improved command, Smith now slots comfortably into the Top 72 tier in our update.

As we roll out our latest update to the RotoProspects Top 700 Prospect fantasy baseball rankings, let’s dive into the key updates surrounding the top-ranked prospects this week.

Trey Yesavage of the Blue Jays soars into the Top 15 with postseason performance

Yesavage’s ascent this season has been nothing short of meteoric — from his major-league debut on September 15, 2025, to being trusted with a start in the 2025 World Series opener just weeks later. In the Toronto Blue Jays’ ALDS Game 2 start versus the New York Yankees, Yesavage went 5⅓ innings of hitless baseball, struck out 11 and became the first pitcher in postseason history to log nine or more strikeouts, allow zero hits, and walk one or fewer batters in the same game.

Then in Game 5 of the World Series he completely dominated the Dodgers, striking out 12 without issuing a walk — setting a rookie postseason strikeout record.

For a pitcher who made just three major-league starts before the playoffs, it was a statement showing.

Konnor Griffin of the Pirates is still No. 1, and for a very good reason

Griffin continues to live up to the hype at just 19 years old. In 2025, he posted a slash line of .333/.415/.527 with an OPS of .941, amassed 162 hits, 21 home runs, 94 RBIs and 65 stolen bases across three levels.

His tool package—especially 70-grade speed and a 60-grade future hit tool—remains elite, and he projects a debut possibly in late-2026. If you want a player who checks every box (hit, power, speed, positional versatility), Griffin is that guy.

Pirates’ Esmerlyn Valdez is near the Top 40 with an explosive AFL showing

Valdez’s rise has been one of the most dramatic in our update. After a solid regular season, his performance in the Arizona Fall League has forced a major reevaluation. In 16 games he has launches eight home runs and 25 RBIs, while also striking out just nine times and walking 17 times.

In the 2025 minor-league season, he hit .286 with 26 homers and 86 RBIs while showing marked improvement in plate discipline.
