EDGE Analysis

Stumpf was selected by Detroit in the Rule 5 draft in December, and the Tigers will need to keep him on the active roster all season, otherwise he will be subjected to waivers and offered back to the Royals. Stumpf will compete with Kyle Ryan and Blaine Hardy in spring training to be a second lefty in the bullpen behind Justin Wilson.

Stumpf was selected by the Tigers with the 11th pick in the Rule 5 draft Thursday.

EDGE Analysis

The 25-year-old southpaw split time between the Phillies and Royals systems last year, failing to make much of an imprint in either organization. He posted a 2.11 ERA and 26:4 K:BB in 21.1 innings at Double-A for the Royals, but was left unprotected, suggesting that his upside is limited. The Tigers will need to keep him on the active roster all season, otherwise he will be subjected to waivers and offered back to the Royals. Look for him to work out of the bullpen in extremely low-leverage situations.

Stumpf returned to the Royals on Tuesday after being designated for assignment by the Phillies.

EDGE Analysis

Since Stumpf was a Rule 5 selection of the Phillies in 2015, he had to be offered back to the Royals before truly becoming a free agent. Kansas City will accept the left-hander, who recently returned from an 80-game PED suspension, and assign him to Triple-A Omaha as a formality. He'll then be transferred to Double-A Northwest Arkansas. Stumpf made seven appearances for the Phillies this season, allowing six earned runs on nine hits across just 5.0 innings.

Stumpf has been designated for assignment by the Phillies on Friday.

EDGE Analysis

The 25-year-old has struggled this season in his time between High-A, Double-A, Triple-A and the majors. In just five innings with the Phillies, Stumpf has a 10.80 ERA and 2.20 WHIP with only two strikeouts. Stumpf was recently activated by the Phillies from an 80-game PED suspension. He was a Rule 5 selection by the Phillies this offseason.

Stumpf (suspension) was reinstated from his 80-game suspension Sunday.

EDGE Analysis

Stumpf was suspended and placed on the restricted list April 14 after testing positive for the PED dehydrochlormethyltestosteron. He completed his suspension and made seven minor league appearances over the last two weeks to get ready for his return. The 25-year-old has not even completed a full major league inning yet in his career and will be used out of the bullpen.

Stumpf (suspension) will likely be activated Sunday, Todd Zolecki of MLB.com reports.

EDGE Analysis

Stumpf is nearing the end of his 80-game suspension for testing positive for a performance enhancing drug. The Rule 5 pick must remain on the Phillies' active roster for the remainder of the season to stay in the organization.

Stumpf (suspension) had his rehab assignment transferred to Double-A Reading, Stephen Gross of The Morning Call reports.

EDGE Analysis

Stumpf is nearing the end of his 80 game suspension due to PED use, and will be eligible to return on July 10. He will head to Double-A Reading in the meantime for a tune up. The 25-year-old had a 40.50 ERA and 4.50 WHIP in 3 appearances prior to being suspended, so whether or not he will return as an effective pitcher is still to be seen.

Stumpf (suspension) will begin a rehab assignment Friday, Corey Seidman of CSN Philadelphia reports.

EDGE Analysis

Stumpf was suspended 80 games earlier this season for testing positive for the PED dehydrochlormethyltestosteron. He will be eligible to return to the Phillies for their last game prior to the All-Star break.

Stumpf was placed on the restricted list Thursday after being issued an 80-game suspension.

EDGE Analysis

No surprises here, as the Phillies will be without the services of Stumpf for 80 games and will need to add bullpen depth in the short term. In Stumpf's place, the team recalled lefty reliever Elvis Araujo from Triple-A Lehigh Valley.
