Royals' Danny Duffy: Out with flexor strain

Duffy was placed on the 10-day injured list with a left forearm flexor strain Monday.

Duffy had been having an excellent season, riding a career-best 28.2 percent strikeout rate to a 1.94 ERA while showcasing his highest velocity (averaging 93.7 mph on his fastball) since 2016. The transaction was backdated three days, so he'll be eligible to return in a week, but that appears highly unlikely given the nature of his injury. Forearm issues can sometimes be the first sign of a very serious injury, though it's unclear if that's the case for Duffy. Kris Bubic will enter the rotation in his absence and will start Tuesday against the Brewers.
