Here's How Ricky Tiedemann Did in Major League Debut

One of the most promising prospects in the Toronto Blue Jays, Ricky Tiedemann, made his major league debut in a game against the New York Yankees on Saturday.

Toronto recalled left-handed pitcher Ricky Tiedemann to the major league roster after years of setbacks due to arm and neck injuries. Tiedemann, who used to be the Blue Jays No. 1 prospect and a top 100 prospect in baseball in his own right, reached the Double-A level in his first minor league year in 2022 and seemed destined for a fast track to the bigs.

Instead, Tiedemann's injuries limited him to 24.1 innings of work from 2024-present, which included a Tommy John surgery that kept him out most of 2024 and all of 2025.

Tiedemann's call-up coincided with a bullpen day for Toronto and got his chance in the second inning of Saturday's game against New York.

The 23-year-old southpaw pitched 1.2 innings, struck out two batters and allowed one earned run on two hits. Tiedemann's velocity topped out at 97 miles per hour and he threw 18 of his 27 pitches for strikes.

Tiedemann was originally picked in the third round of the 2021 MLB Draft out of Golden West Junior College and was instantly praised for his potential and arsenal.

Despite the injuries, MLB Pipeline still had Tiedemann ranked as the Blue Jays' 11th-best prospect.

The publication had the following scouting report on the former juco product.

"When he’s healthy, Tiedemann’s talent is undeniable. His fastball is back in the 96-98 mph range, and he’s throwing a new slider, one focused on lessening the strain on his elbow after bone chips were also removed during that surgery. It’s going to be a harder, tighter slider that could take some time to re-develop, but paired with a strong changeup, all of the pieces are there for Tiedemann to mow through big league hitters if he can only stay on the mound long enough to build some momentum."

Tiedemann was originally brought up as a starter within Toronto's farm system but, aside from two rehab outings with the Florida Complex League Blue Jays, he's been used exclusively as a reliever while he's been on his rehab assignment.

This season, the former third-round draft pick will likely be exclusively used as a reliever, in part due to his injury history. It's still unknown whether the Blue Jays will keep Tiedemann in that role or if they plan to ramp him up again as a starter in the future.
