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.
