Toronto optioned Tiedemann to Triple-A Buffalo on Sunday.
After striking out two batters and allowing one run in 1.2 innings of relief in his major-league debut during Saturday's 4-1 win over the Yankees, Tiedemann will head right back to Buffalo. He'll give up his spot on the active roster to reliever Brendon Little, who was reinstated from the paternity list. Tiedemann is likely to continue working out of the bullpen for the remainder of the season, but the Blue Jays could revisit developing the left-hander as a starter next spring.

Blue Jays' Ricky Tiedemann: Fans two in big-league debut
Rotowire
Tiedemann gave up a run on two hits and struck out two over 1.2 innings in Saturday's 4-1 win over the Yankees.
The Blue Jays went with a bullpen game, and Tiedemann made his much-anticipated big-league debut as the second pitcher into the contest after Braydon Fisher. While Tiedemann did give up an RBI single to George Lombard in the second inning, the 23-year-old southpaw also fanned Austin Wells and Ben Rice while averaging 96.2 mph with his fastball. Tiedemann's future could still be in the rotation, but after injuries have plagued him throughout his minor-league career, Toronto will let him get his feet wet as a multi-inning option out of the bullpen down the stretch.

Blue Jays' Ricky Tiedemann: Recalled from Buffalo
Rotowire
The Blue Jays recalled Tiedemann from Triple-A Buffalo on Saturday.
Tiedemann only recently returned to game action after undergoing Tommy John surgery in July 2024, with his time on the shelf getting extended due to setbacks with his elbow and neck. Over three innings for Buffalo this season he's given up four earned runs across three innings with a 4:2 K:BB. Despite his shaky performance in the minors, the 23-year-old southpaw will report to the Blue Jays to provide bullpen depth, replacing Chase Lee.

Blue Jays' Ricky Tiedemann: Given injections for neck
Rotowire
Tiedemann (elbow) will be given injections for his injured neck, Ben Nicholson-Smith of Sportsnet.ca reports.
Nagging neck problems have prevented Tiedemann from making any rehab starts over the past two weeks. He had previously made a pair of one-inning rehab appearances with the Blue Jays' rookie-level Florida Complex League affiliate. Tiedemann initially landed on the 7-day injured list at Triple-A Buffalo as he continues to work his way back from left elbow surgery. It's unclear when he might be ready to pitch again.

Blue Jays' Ricky Tiedemann: Cleared for mound work
Rotowire
Tiedemann (elbow) has been throwing bullpens at Toronto's Player Development Complex in Dunedin, Shi Davidi of Sportsnet.ca reports.
Tiedemann was shut down from throwing in February after experiencing left elbow soreness. However, he's since gained clearance to resume mound work in mid March and has lately progressed to side sessions. The Blue Jays haven't provided a clear timetable for his return, but he'll report to Triple-A Buffalo once healthy.

Blue Jays' Ricky Tiedemann: Remains shut down from throwing
Rotowire
Blue Jays manager John Schneider said Friday that Tiedemann (elbow) has yet to resume a throwing program, Arden Zwelling of Sportsnet.ca reports.
Tiedemann was shut down a couple weeks ago after feeling left elbow soreness following a bullpen session. An MRI cleared the lefty of structural damage, and Schneider noted that Tiedemann could be cleared to resume throwing "hopefully in the next couple of days."

Blue Jays' Ricky Tiedemann: Not ruled out as relief option
Rotowire
The Blue Jays have left the door "cracked open" for Tiedemann to contribute in a relief role this season, Keegan Matheson of MLB.com reports.
Tiedemann -- who was added to the 40-man roster this winter -- is without restrictions this spring after missing the entire 2025 campaign following Tommy John surgery. The Blue Jays still view the lefty as a starting pitcher long-term, but he might have a better chance to break into the big leagues in a bullpen role. Tiedemann has totaled just 140 innings in the minors since being drafted by Toronto in 2021 and didn't throw a pitch in 2025, so he'll have workload restrictions in 2026. Working in relief would help curtail that workload, but Tiedemann will likely begin the season in the rotation at Triple-A Buffalo.

Blue Jays' Ricky Tiedemann: Expected to be fully healthy for ST
Rotowire
Tiedemann (elbow) is expected to be fully healthy in time for camp, Keegan Matheson of MLB.com reports.
Tiedemann missed the entire 2025 season after undergoing Tommy John surgery in July of 2024, and he has totaled just 140 innings in the minors since being drafted by Toronto in 2021. Despite that, it was still an easy call for the Blue Jays to add Tiedemann to the 40-man roster in November for Rule 5 protection. While the hard-throwing lefty has flashed high upside and is close to full health, Tiedemann is highly unlikely to handle a big workload in 2026 given all the missed time. "Hopefully he's a factor for us in our rotation," GM Ross Atkins said. "That's the plan, but we would be open to him impacting the team in a bulk role or some creative way, depending on how things are going."

Blue Jays' Ricky Tiedemann: Joins 40-man roster
Rotowire
The Blue Jays selected Tiedemann's (elbow) contract from Triple-A Buffalo on Tuesday.
Tiedemann missed the entire 2025 season while working his way back from the Tommy John procedure he underwent in July 2024. The Jays haven't offered an update on whether he'll be ready to go by the start of spring training, but his addition to the 40-man roster ensures he won't be plucked away in the Rule 5 Draft. The 23-year-old lefty is considered one of the top pitching prospects in Toronto's system and is a candidate to make his MLB debut at some point in 2026.

Blue Jays' Ricky Tiedemann: Aiming for late 2025 return
Rotowire
Tiedemann (elbow) hopes to be ready to pitch in games before the end of the 2025 season, Keegan Matheson of MLB.com reports.
Tiedemann underwent Tommy John surgery in late July of last year, so it's not a guarantee he'll be game-ready at any point this year. If he is, it's almost surely not going to come at the major-league level -- however, a minor-league stint late in 2025 would position the southpaw for a normal offseason next winter before he competes for a role on the 2026 Blue Jays. Tiedemann has some of the best pure stuff outside of the majors but has had a tough time staying healthy, with his career high of 78.2 innings coming back in 2022.

Blue Jays' Ricky Tiedemann: Dominant in Single-A
Rotowire
Tiedemann (elbow) struck out five over 2.1 scoreless, no-hit innings in a rehab start for Single-A Dunedin on Wednesday, Keegan Matheson of MLB.com reports.
Over his last two appearances for Dunedin, Tiedemann has allowed zero runs or hits while posting a 9:2 K:BB in 4.1 innings. The 21-year-old southpaw appears close to coming off the minor-league injured list and rejoining the staff at Triple-A Buffalo, but he would need to be built up further before the top prospect would be an option for the big-league rotation.

Blue Jays' Ricky Tiedemann: Returning to mound Friday
Rotowire
Tiedemann (elbow) will make a rehab start with the Blue Jays' Florida Complex League affiliate Friday, Sam Dykstra of MiLB.com reports.
It will be the top prospect's first appearance since April 11, as he's been sidelined with left ulnar nerve inflammation in his pitching elbow. Tiedemann will eventually move up to Triple-A Buffalo, where he began this season before getting hurt. He's a candidate to join the Blue Jays at some point this season, but Tiedemann figures to remain in the minors for a while as he attempts to prove he can be healthy and effective for an extended period.

Blue Jays' Ricky Tiedemann: Close to rehab assignment
Rotowire
Tiedemann (elbow) threw a live batting practice session Friday and could begin a rehab assignment this week, Shi Davidi of Sportsnet.ca reports.
The 21-year-old lefty last pitched April 11 for Triple-A Buffalo before being shut down with what was diagnosed as ulnar nerve inflammation in his elbow, but he's close to resuming game action. Tiedemann will likely begin his rehab stint in the Florida Complex League or with Single-A Dunedin, and he could rejoin the Buffalo rotation by the end of June. If Tiedemann can manage to stay healthy, he remains a candidate to bolster the major-league staff in the second half.

Blue Jays' Ricky Tiedemann: Throwing off mound again
Rotowire
Tiedemann (elbow) is back on a mound and throwing bullpens according to Blue Jays general manager Ross Atkins, Scott Mitchell of TSN.ca reports.
Tiedemann has been out with ulnar nerve inflammation in his left elbow since late April and the team has been cautious in its approach to his recovery. Atkins said that the top prospect will be back in game action "relatively soon" and one silver lining of the injury is that it removed any concern about limiting his workload down the road this season.

Blue Jays' Ricky Tiedemann: Begins throwing again
Rotowire
Tiedemann (elbow) has resumed throwing at the Blue Jays' spring training complex in Dunedin, Arden Zwelling of Sportsnet.ca reports.
The 21-year-old left-hander is currently only throwing from flat ground, and it could be a couple weeks before Toronto puts him back on a mound. There's no timeline yet for Tiedemann's return to game action, and the Jays aren't going to rush their top pitching prospect. He hasn't pitched since April 11, stumbling to a 5.63 ERA with a 10:9 K:BB over eight innings in three appearances for Triple-A Buffalo before being shut down.

Blue Jays' Ricky Tiedemann: Ulnar nerve issue in elbow
Rotowire
Tiedemann has been diagnosed with ulnar nerve inflammation in his left elbow, Kaitlyn McGrath of The Athletic reports.
The hope is that Tiedemann will be ready to begin throwing again in 7-to-10 days. All things considered, it's a very favorable diagnosis for the top pitching prospect. Tiedemann was struggling at Triple-A Buffalo before getting hurt, posting a 5.63 ERA, 2.00 WHIP and 10:9 K:BB over eight frames.

Blue Jays' Ricky Tiedemann: Meeting with doctors
Rotowire
Tiedemann (elbow) is set to meet with doctors in Toronto this week, Ben Nicholson-Smith of Sportsnet.ca reports.
Keegan Matheson of MLB.com notes that the meeting was prompted by Tiedemann experiencing elbow discomfort. Prior to landing on the 7-day IL on April 18, Tiedemann made three starts with Triple-A Buffalo, going 0-1 while posting a 5.63 ERA, 2.00 WHIP and 10:9 K:BB over eight frames.

Blue Jays' Ricky Tiedemann: Lands on injured list
Rotowire
Tiedemann (undisclosed) was placed on the 7-day injured list Thursday, Hazel Mae of Sportsnet reports.
There were no details provided about the injury. Tiedemann had gotten off to a shaky start to the minor-league season with Triple-A Buffalo, allowing five earned runs across eight innings while walking seven, and he hasn't pitched since April 11. Any possibility of a big-league debut later this season is on hold until his health situation becomes clearer.

Blue Jays' Ricky Tiedemann: In mix for opening series start
Rotowire
Blue Jays manager John Schneider said Friday that Tiedemann is "in the mix" to make the Opening Day roster and get a start during the first series of the season in Tampa Bay, Rob Longley of the Toronto Sun reports.
Tiedemann's potential inclusion on the Opening Day roster hinges on whether Kevin Gausman (shoulder) is ready for a start during the opening series or needs a short stint on the injured list. Mitch White is the favorite to handle the assignment, with Yariel Rodriguez, Wes Parsons and Paolo Espino also in the mix along with Tiedemann to fill in for Gausman. It's difficult to envision the young left-hander winning out if he would only be needed for one start, but the fact that he's even being considered points to his potential to reach the majors sooner rather than later.

Blue Jays' Ricky Tiedemann: Works on back field Sunday
Rotowire
Tiedemann (hamstring) faced live hitters on a backfield Sunday and could see game action later this week, Keegan Matheson of MLB.com reports.
"It also depends on starting to run again, starting to field, making sure all of that is intact, because you're going to get those ground balls to first base where I need to run over and cover," Tiedemann said after Sunday's session. "I've got to be able to do that, but I think this week, I'll be in." The flamethrowing lefty faced a group of hitters that included big-leaguers Daulton Varsho, Cavan Biggio (shoulder) and Isiah Kiner-Falefa and leaned heavily on his slider with impressive results. Tiedemann estimates he could build up to a four-inning workload by the end of camp, and that might be enough to have the Blue Jays' top pitching prospect begin the year on the Opening Day roster, as both Kevin Gausman and Alek Manoah are currently dealing with shoulder issues.
