Duffy allowed three earned runs on seven hits and one walk with three strikeouts as he took the no-decision in the Royals' 6-4 win over the Orioles on Sunday.

EDGE Analysis

Duffy had previously been on the mend for a little over three weeks as he was recovering from a left hamstring strain. He lucked out as he was able to return in a favorable matchup against the Orioles, except he was not able to keep them off the scoreboard as he gave up runs in the first, fourth and sixth innings. Duffy now owns a 4.89 ERA to compliment a 92:37 K:BB ratio over 106.2 innings of work. He is scheduled to make his next start Sunday in Miami.

Duffy (hamstring) was reinstated from the 10-day injured list ahead of his scheduled start Sunday against the Orioles.

EDGE Analysis

Duffy was on the shelf for approximately three weeks with a left hamstring strain, but he proved his health with a pair of strong, five-inning rehab starts with Double-A Northwest Arkansas on Aug. 20 and 25. The southpaw isn't expected to face any significant restrictions in his return to big-league action and should at least make for a decent streaming option while matching up with a porous Orioles offense.

Duffy (hamstring) will return from the injured list to start Sunday against Baltimore, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

Duffy's final rehab appearance came Sunday, so he'd likely be ready to pitch sooner, but the Royals will wait until rosters expand on Sept. 1 to avoid sending someone down. The lefty will wind up missing just shy of a month with a hamstring strain.

Duffy (hamstring) will be activated from the injured list sometime this week, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

Duffy has been on the IL since Aug. 4 with a hamstring injury, but he's been cleared to rejoin the big-league rotation after getting through a rehab appearance with no issues over the weekend. The lefty allowed one run on four hits across five innings for Double-A Northwest Arkansas on Sunday, striking out four and issuing zero walks in the process. Duffy fired 72 pitches in that outing, so he'll likely face some sort of pitch limit in his first start back, which should come at home against Baltimore over the weekend.

Duffy (hamstring) will make a rehab start Sunday with Double-A Northwest Arkansas.

EDGE Analysis

Duffy has been on the injured list since Aug. 4 and is thus in need of a rehab assignment prior to returning to the majors. It's unclear whether he will join the team after one warmup outing, or if multiple appearances will be required. Eric Skoglund is set to fill his spot in the rotation Sunday.

Duffy (hamstring) will go on a rehab assignment with Double-A Northwest Arkansas before returning to the big-league rotation, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

He will presumably pitch Sunday, and it is unclear if he will need more than one start before he is activated. Eric Skoglund will start Sunday's game for the Royals in his place.

Duffy (hamstring) will throw a four-inning simulated game Tuesday, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

The lefty made it through two innings against live hitters last Friday and reported feeling good afterward. He will build up to four innings Tuesday, and Flanagan says that if all goes well, Duffy could be activated to start this weekend in Cleveland. Duffy was rocked for eight runs Aug. 3 before landing on the IL, but he had been serviceable in his prior nine starts, posting a 4.22 ERA, 1.33 WHIP and 50:18 K:BB in 53.1 innings.

Duffy (hamstring) felt good after pitching a two-inning simulated game Friday, Jeffrey Flanagan of MLB.com reports.

EDGE Analysis

As expected, Duffy fired a sim game Friday, and the Royals were pleased to report that everything went as planned. He'll be re-evaluated Saturday to determine the next step in his recovery process.

Manager Ned Yost said Duffy (hamstring) will throw a two-inning simulated game later in the week, Lynn Worthy of The Kansas City Star reports.

EDGE Analysis

Duffy has been sidelined since August 6 with a left hamstring injury. A date for his potential return to the rotation will hopefully come into focus following his simulated outing.

Duffy (hamstring) is expected to miss just a start or two, Joel Goldberg of Fox Sports Kansas City reports.

EDGE Analysis

Duffy strained his hamstring while running Monday and landed on the 10-day injured list Tuesday. Jorge Lopez is the leading candidate to fill in for him until he returns.
