Stumpf (elbow) was designated for assignment by the Tigers on Thursday, Emily Waldon of The Athletic reports.

EDGE Analysis

Stumpf was already a non-tender candidate due to his role as a lefty specialist, as the league will implement a three-batter minimum for pitchers in 2020, and he now finds himself off the team's 40-man roster. The 28-year-old cleared waivers and opted to become a free agent, Jason Beck of MLB.com reports. In 48 appearances this season, the southpaw recorded a 4.34 ERA with 28 strikeouts over 29 innings pitched.

The Tigers placed Stumpf on the 60-day injured list Monday with a left elbow strain.

EDGE Analysis

Stumpf's injury won't necessarily keep him out of commission for two months, but the move to the 60-day IL officially ends his season and opens up a 40-man roster spot for reliever Marcos Diplan, whom the Tigers claimed off waivers from Minnesota. A lefty specialist who likely won't bring much utility with the MLB implementing a three-batter minimum for pitchers in 2020, Stumpf looks like a potential non-tender candidate for the Tigers this winter.

Stumpf was recalled from Triple-A Toledo on Monday, Chris McCosky of The Detroit News reports.

EDGE Analysis

Stumpf compiled a 4.44 ERA and 1.75 WHIP across 26.1 innings with the Tigers earlier in the season but dominated after being sent to Toledo in July, posting a 0.59 ERA, 0.79 WHIP and 24:4 K:BB across 15.1 innings while notching two wins and four saves. The southpaw will provide the big club with bullpen reinforcements for the stretch run.

Stumpf was optioned to Triple-A Toledo on Wednesday.

EDGE Analysis

Stumpf has been on the big-league roster all season and has pitched capably enough, recording a 4.44 ERA in 26.1 innings. Both his 20.2 percent strikeout rate and 10.5 percent walk rate are worse than average, though not by a large amount. He'll make way for Drew VerHagen, whose contract will be selected in a corresponding move.

The Tigers recalled Stumpf from Triple-A Toledo on Sunday.

EDGE Analysis

With lefty reliever Buck Farmer moving into the rotation to make a spot start Sunday against the Twins, Stumpf will move up to the big club to give the Tigers another southpaw out of the bullpen. Over 41 appearances with Detroit this season, Stumpf has submitted a 7.11 ERA and 2.01 WHIP across 25.1 innings and will likely see his usage limited mainly to lefty-on-lefty matchups.

Stumpf was optioned to Triple-A Toledo on Wednesday, Jason Beck of MLB.com reports.

EDGE Analysis

Artie Lewicki will take Stumpf's place on the active roster after the latter was cast off the 25-man prior to Wednesday's game. Across 41 relief appearances with the Tigers this year, Stumpf has logged an abysmal 7.11 ERA and 2.01 WHIP with a 5.3 BB/9.

Stumpf (elbow) has returned to health and will be recalled from Triple-A Toledo, John Wagner of The Toledo Blade reports.

EDGE Analysis

Stumpf has appeared in 28 games for Detroit this season, accruing a 5.71 ERA and 1.90 WHIP with 14 strikeouts over 17.1 innings. He'll likely be used in low-leverage situations out of the bullpen, given his alarming ERA.

Stumpf (elbow) will begin a minor-league rehab assignment with Triple-A Toledo on Tuesday.

EDGE Analysis

Stumpf has been on the disabled list since May 30 with ulnar nerve irritation, but he's been cleared to return to game action after getting through a bullpen session with no issues over the weekend. He's expected to need at least two rehab appearances before rejoining the Tigers.

Stumpf (elbow) is set to embark on a rehab assignment with Triple-A Toledo in the next couple days, Jason Beck of MLB.com reports.

EDGE Analysis

Stumpf recently threw his first bullpen session since landing on the DL with left ulnar irritation in late May and could see time in the minors as soon as this weekend if everything goes according to plan. It's expected that he will require multiple outings with the Mud Hens before returning to Detroit.

Stumpf (elbow) will throw a bullpen session this week, Chris McCosky of The Detroit News reports.

EDGE Analysis

Stumpf is having no issues throwing all of his pitches from flat ground, so he'll progress to mound work for the first time since landing on the disabled list near the end of May. The lefty will eventually need to face live hitters before returning, leaving his possible return date up in the air.
