Stumpf (elbow) threw from flat ground Thursday, Chris McCosky of The Detroit News reports.

EDGE Analysis

Stumpf landed on the disabled list at the end of May with an elbow injury, but he's already resumed throwing a program after an MRI cleared him of any structural damage. He'll continue to ramp up his throwing intensity before eventually being cleared to head out on a minor-league rehab stint.

Stumpf was cleared of any structural damage to his left elbow after undergoing an MRI on Wednesday, Chris McCosky of The Detroit News reports.

EDGE Analysis

Stumpf was placed on the 10-day disabled list Tuesday after experiencing irritation in the ulnar nerve of his elbow, but follow-up examinations revealed that the ligament is still intact. The 27-year-old is expected to rest up for a few days to allow the inflammation in the elbow to subside before resuming a throwing program.

Stumpf was placed on the 10-day disabled list Tuesday with left ulnar irritation, Chris McCosky of The Detroit News reports.

EDGE Analysis

Stumpf last pitched on Monday, walking the only batter he faced. He is apparently dealing with some swelling in his elbow which has caused tingling in his fingers. He was seen by a specialist who suggested that he take some time off. Johnny Barbato was recalled from Triple-A Toledo to fill Stumpf's spot in the bullpen.

Stumpf (1-2) was tagged with the loss and a blown save Monday against the Rangers. He retired just one of the three hitters he faced, allowing an earned run on two hits.

EDGE Analysis

Stumpf came on in the seventh inning with a runner on base and two outs, and he promptly allowed a single to Shin-Soo Choo to bring home the inherited runner to tie the game. He then gave up a triple to Jurickson Profar that plated the go-ahead run. Stumpf has taken the loss in two of his last three appearances, and he's allowed three earned runs over an inning of work in that time to bump his season ERA up to 3.55.

Stumpf (1-1) was charged with the loss Friday against the Royals, allowing two earned runs on two hits while retiring just a single batter.

EDGE Analysis

Stumpf relieved starter Francisco Liriano with no outs and one on in the eighth, and he proceeded to allow singles to Jon Jay and Alex Gordon before getting the hook. Both runners would come around to score against Joe Jimenez. The subpar performance bumped Stumpf's season ERA from 1.54 up to 3.00.

Stumpf (1-0) recorded his first win of the season in Game 1 of Wednesday's doubleheader with the Pirates by tossing 1.1 scoreless innings of relief while striking out one.

EDGE Analysis

In a game that featured 23 total runs and 34 hits, Stumpf was one of the few pitchers who performed effectively. The lefty now has a solid 2.16 ERA for the season. His fantasy value is limited due to his middle relief role, but he should continue to be one of Detroit's most reliable bullpen options.

After a scoreless outing in Thursday's Grapefruit League loss to the Braves, Stumpf has his spring training ERA down to 2.57 across seven innings.

EDGE Analysis

Stumpf is likely going to be the team's top left-handed option this season, and he's looking the part in spring training. Stumpf profiles as a true LOOGY for the Tigers, as righties posted an .873 OPS against him last season. That makes him valuable in Detroit, but limits his fantasy appeal outside of leagues that count holds.

Tigers pitching coach Chris Bosio suggested Wednesday that Stumpf will enter the season as the team's top left-hander out of the bullpen, Chris McCosky of MLive.com reports. "Big stuff, great stuff," Bosio said of Stumpf. "This guy knows what he's doing. We are trying some things with him and he's got the aptitude to do it, as well. We've got a special left-handed reliever right there in Daniel."

EDGE Analysis

So far in spring training, Stumpf has picked up where he left off in 2017, when he finished the season as the Tigers' undisputed top southpaw reliever. Considering the lack of impact arms in the Detroit bullpen, however, that distinction doesn't mean a whole lot for Stumpf, who remains best suited for a true LOOGY role rather than one that requires him to record three-plus outs against hitters from either side of the dish. Opposing righties torched Stumpf last season to the tune of a .873 OPS, a 261-point difference from his mark against lefties.

Stumpf threw a new, slower changeup in his spring outing against the Blue Jays on Saturday, The Detroit News reports.

EDGE Analysis

Stumpf had an upper-80s changeup last year, though he only threw it 6.7 percent of the time. Saturday's changeups were clocked in the lower 80s. A more effective changeup would give Stumpf a potential weapon against right-handed hitters, who hit .293 off of him last season. The 27-year-old hasn't been a particularly fantasy-relevant pitcher thus far in his career, putting up a 4.34 ERA in 42.2 innings. Relievers can develop out of seemingly nowhere, though, so if Stumpf shows positive results early in the season, it may be a new pitch and not a total fluke, making him a potential deep-league option.

Stumpf recorded his eighth hold of the season in Thursday's win over the Royals. He pitched a scoreless inning with no hits or walks allowed.

EDGE Analysis

Stumpf has been one of the few Detroit relievers to post decent numbers this season, as he now has a 3.89 ERA for the year. However, he'll have to get that 1.41 WHIP down in 2018 if he wants to sustain success out of the bullpen.
