Ryan Jennings looked like a sure thing for the major leagues after he posted an amazing 1.93 ERA in 2024 and won Minor League Pitcher of the Year for the Toronto Blue Jays. Even though he was ranked as the team’s 22nd-best prospect, the 26-year-old right-hander has officially walked away from baseball. His choice comes after a tough time adjusting to Triple-A and dealing with injuries that kept coming back.

“A few weeks ago I decided to retire from the game of baseball,” Jennings wrote in an Instagram post. “What an unbelievable blessing this journey was! From championships to call-ups and everything in between, I can’t explain how grateful I am to have gotten this opportunity.”

Jennings retired as a reliever for the Triple-A Buffalo. Originally drafted from Louisiana Tech University, he began his pro pitching career with Single-A Dunedin. After posting a 2.16 ERA across five outings out of the bullpen in his first year, Jennings was promoted to High-A Vancouver in the following season. There, he took the role of a starter and continued as one till he was promoted.

His breakout year was 2024. Jennings pitched across two minor league levels, the High-A Vancouver and the Double-A New Hampshire Fisher Cats. He put up a fantastic 1.93 ERA in 21 games (12 starts), even though his win-loss record was 0-5. Jennings was also invited to the Blue Jays’ Spring Training.

The 2025 season began on a high note for Jennings as the Blue Jays called him up again to Spring Training as a non-roster invitee. Across three Grapefruit League games, he allowed only one run after throwing 4.2 innings. Jennings incredible outings quickly caught attention as he advanced to the Triple-A. There, he transitioned into a full-time reliever. His first season of relief pitching came with ups and downs, as Jennings posted a 1-3 record with a 4.25 ERA in 34 games.

“The hardest part of the transition was getting used to the short burst of energy needed as a reliever,” Jennings reportedly revealed. “As a starter, you are mentally prepared for the long haul, whereas a reliever has a much shorter competitive window.”

On top of learning a new role, injuries kept holding him back. In 2026, he pitched in two Grapefruit League games, taking a 1-0 loss. He was optioned to Triple-A Buffalo on March 27. He began the season on the 7-day IL. By the time of his retirement announcement, Jennings had not played any official matches this season.

Jennings’ transition into a full-time reliever was not smooth; he faced multiple challenges, including injuries, and eventually retired. He ended his pro baseball career with a 3.07 ERA and a 7-13 record in 83 minor league games.

While the Blue Jays’ farm system will miss a talented pitcher, their major league rotation is set to receive a boost as Dylan Cease returns against the Phillies.

Dylan Cease returns from 15-day IL

The Toronto Blue Jays perhaps have one of the highest numbers of pitchers on the injured list. Dylan Cease recently became one of them as he landed on the 15-day IL with a hamstring injury on May 24. During his IL stint, Cease missed two of his scheduled starts.

However, after one rehab outing in Triple-A Buffalo, the Blue Jays have decided to reinstate Cease on Tuesday against the Phillies. In his singular rehab start, Cease struggled with command and control issues. He surrendered five earned runs on six hits, including two homers, and a walk. However, Cease is one of the key rotation pieces of the Blue Jays, as he led the league in strikeouts (92) before his injury.

As Cease returns to the rotation, the Blue Jays have reportedly optioned Adam Macko to Triple-A. Following a mid-May call-up, Macko was dominant with a 1.50 ERA in 12 outings. He also started one game.

Cease, on the other hand, holds a 3-3 record with a 3.05 ERA across 11 starts and 62 innings so far in the season. Under a seven-year, $210 million contract, this is the 30-year-old’s first season in Toronto.
