Duffy (hamstring) ran at 85 percent Friday, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Duffy said his hamstring felt "okay" and he was still a little sore Saturday, so he still has a few hurdles to cross before he is ready to play for the Rays again. There is currently no timetable for Duffy's return, but he is hoping to be back on the field at some point this season.

Duffy (hamstring) is scheduled to take batting practice and then get 4-to-5 at-bats in a simulated game Tuesday, Juan Toribio of MLB.com reports.

EDGE Analysis

Duffy was placed on the injured list at the beginning of the season due to a left hamstring strain, though he appears to be making steady progress after it was determined that he won't require surgery. A timetable for his return is still up in the air at this point, but the team should get a better idea on the next steps in his recovery process following Tuesday's activities.

Duffy (hamstring), who will see Dallas-area specialist Dr. Dan Cooper on Wednesday, does not expect to require surgery and anticipates playing at some point this season, Marc Topkin of the Tampa Bay Times reports.

EDGE Analysis

Duffy has battled hamstring injuries since early in camp and has dealt with a number of setbacks. It's good news that he doesn't expect the latest issue to be season-ending, but athletes tend to skew optimistic when it comes to their own injuries. A clearer picture of his return timeline should emerge once he's evaluated by a doctor.

Duffy, whose rehab has been paused after he felt tightness in his left hamstring during a rehab game with Triple-A Durham last Wednesday, will be evaluated "over the next few weeks", Juan Toribio of MLB.com reports.

EDGE Analysis

The veteran infielder's latest setback unsurprisingly left him very frustrated, considering it appeared Duffy was just a handful of rehab games away from finally making his 2019 majors debut. For the moment, it appears it's several steps back for Duffy, and a return around the All-Star break could well be the likeliest best-case scenario.

Duffy was removed from Wednesday's game with Triple-A Durham after aggravating his left hamstring injury, Neil Solondz of the Rays Radio Network reports.

EDGE Analysis

Duffy was playing the outfield during his rehab assignment with the Bulls, but apparently aggravated the issue running out a groundball, per Durham broadcaster Patrick Kinas. The 28-year-old had his rehab stint "paused" for a few days a couple weeks ago, but Wednesday's aggravation has potential to be an actual setback. Duffy has been battling the hamstring issue since late February.

Duffy (hamstring) stated in left field in Triple-A Durham's win over Norfolk on Tuesday and went 0-for-4 before being replaced for a pinch hitter in the eighth inning.

EDGE Analysis

It was yet another important step in the recovery process for Duffy, who's played third base, shortstop, designated hitter, and now, left field, during his rehab. The veteran infielder hasn't had much success at the plate in his minor-league outings, but of greater importance is that his balky hamstring has passed all of the tests it's been put through. The earliest date Duffy can come off the injured list is next Monday.

Duffy (hamstring) will play left field during Tuesday's rehab game with Triple-A Durham, Steve Carney of Sports Radio 620 WDAE reports.

EDGE Analysis

It seems like the Rays are preparing Duffy for a utility role once he comes off the 60-day injured list. He has also played shortstop in addition to his natural position of third base during this rehab stint. Duffy hit .250/.478/.563 with one home run in 16 at-bats while rehabbing with High-A Tampa.

Duffy (hamstring) served as the designated hitter in High-A Charlotte's win over Clearwater on Sunday and went 3-for-4 with a triple, a solo home run, a walk and four runs overall.

EDGE Analysis

After surprisingly struggling at the plate against High-A arms over the first six games of his rehab assignment, Duffy finally looked like a big-league hitter facing inferior competition Sunday. The veteran infielder is likely to get a few more games at the minor-league level in order to pile up more at-bats and further test his recovering hamstring, with a bump up the organizational ladder to the high minors likely before he's activated.

Duffy (hamstring) started at shortstop in High-A Charlotte's loss to Clearwater on Saturday and went 0-for-2 with a walk.

EDGE Analysis

Duffy is now hitting just .083 in his rehab assignment despite the low level of competition, but of overriding importance is the fact he's remained free of setbacks. The fact he played shortstop Saturday hints at the possibility Duffy might see time there at the big-league level when he returns if Willy Adames and Daniel Robertson continue to underperform, Marc Topkin of the Tampa Bay Times reports.

Duffy (hamstring) filled the designated hitter role in High-A Charlotte's win over Daytona on Thursday and went 0-for-2 with a walk.

EDGE Analysis

Duffy is now just 1-for-10 with three walks across his five rehab games, and he's alternated between third base and designated hitter over that span. Offensive struggles aside, the most important aspect of Duffy's rehab is that he's remained free of setbacks after his recovery endured some fits and starts prior to this point. The veteran infielder is expected to move his rehab up to Triple-A Durham at some point in the coming days.
