Toronto Blue Jays Top Dynasty Prospects-September Edition

A rare pitching performance highlights a fun month for the Jays

The division reports debuted last year. The goal of this article series is to provide a quick overview of all dynasty-relevant information from each division. Each team has multiple minor league levels, each containing plenty of impactful prospects which can feel impossible to keep up with. This article series, which will be updated once per month, will help dynasty managers stay up-to-date on performances, injuries, promotions, and more. New this season is the inclusion of tiers in the rankings. Next to their rank, each prospect is assigned a tier. The tier range is 1-5.

  • Tier 1: A potential difference-making dynasty prospect. Somebody who would rank in the top-20ish prospects for dynasty baseball
  • Tier 2: A still very good dynasty prospect who holds plenty of value. This prospect would typically rank in the 21-75 range
  • Tier 3: A mid-tier prospect who could be valuable but has questions and concerns present in his profile ranking in the 76-150 range
  • Tier 4: A prospect who is worth knowing, but is reserved for deeper leagues. This prospect would rank 151-250
  • Tier 5: The rest of the prospects fall into Tier 5

Up North, the Toronto Blue Jays are working to re-establish a depleted system. As the team fell out of the race last season, they made several key trades to acquire talent while also landing a very talented draft class. The system still lacks overall depth, but things are trending up for the Jays. Here are their top prospects!

Top 10 Prospects

Notable Prospect Promotions and News

  • The Blue Jays’ #1 prospect and one of the top pitching prospects in the game has now jumped to Triple-A. 22-year-old Trey Yesavage, a first-round pick from 2024, joined Buffalo on August 22nd, reaching his fourth level this season, his first as a pro. Yesavage has been utterly dominant in 2025. The ECU grad ranks in the Top 5 or better in strikeouts, strikeout rate, Ks per nine, K-BB rate, swinging strike rate, opposing average against, FIP, and xFIP among Minor League pitchers. In 94 2/3 innings, Yesavage has punched out 156 hitters against just 39 walks. That’s good for a K-BB rate of 31.1%, edging Jonah Tong as the best mark in the Minors. While Yesavage will not debut for the Jays this season, he is likely in their Opening Day rotation next Spring.
  • An intriguing name that’s popped up this season has been Silvano Hechevarria. The 22-year-old Cuban righthander was highly impressive in a limited sample last season in the DSL, posting a 1.84 ERA and 57 strikeouts across 49 innings. Hechevarria started 2025 in the Complex, moved to Class A in May, and was promoted to High-A on August 10th. He’s nearly doubled his innings output this season, logging 81 1/3 across 18 appearances (13 starts). Overall, Hechevarria has a 2.21 ERA with 75 strikeouts across three levels. Although he’s not racking up the strikeouts as often as he did in the DSL, Hechevarria is doing a nice job of limiting damage and avoiding hard contact. Keep him on your radar ahead of 2026.

Notable Prospect Performances

  • Gage Stanifer is yet another Jays’ pitching prospect making a name for himself in 2025. Stanifer took a while to find his footing, struggling to an ERA north of 6.00 and a WHIP of over 1.60 in his first 102 1/3 innings as a pro since he was drafted in 2022. In an identical sample this season (102 IP), the 21-year-old has already climbed three levels, having recently been promoted to Double-A. His ERA this season is 2.56, and he’s increased his strikeouts by over four per nine innings, while also cutting his walk rate by nearly 7%. Stanifer’s best month of 2025 was August, pitching at High-A Vancouver. He made six starts, tossing 32 innings with a 1.69 ERA and 1.09 WHIP. He had 42 strikeouts against 11 walks, which was also his lowest walk rate in any single month in his career (8.6%). Stanifer has taken his game to the next level in 2025, and it will be exciting to see how he continues to develop into next season.
  • Jake Casey, the son of former MLB-er Sean Casey, has gotten off to a strong start to his pro career. Casey, a 15th-round pick this summer out of Kent State, has a .966 OPS through his first 21 games as a pro, including a two-homer game on August 19th. During his final season with the Flashes, Casey was first team All-MAC when he hit .356 with 17 homers and 20 steals in 56 games. Casey is currently playing at Class A Dunedin, where he is an outfielder. Although he’s not a top-rated prospect, having an MLB lineage and a successful career in the NCAA, Casey is worth keeping an eye on.
