General manager Dayton Moore expressed confidence Tuesday in Duffy's ability to pitch again this season and estimated he'll return within 3-4 weeks, Lynn Worthy of The Kansas City Star reports.

EDGE Analysis

Duffy went down July 20 with a flexor strain in his left forearm, but Moore's comments Tuesday suggest the lefty will be back on the mound in about a month, at the latest. Duffy has been the Royals' best starting pitcher in 2021, posting a 2.51 ERA and 65:22 K:BB in 61 innings across 13 outings. More details about his recovery and a specific return timeframe should become clear in the next week or two.
