Kelly (hamstring) was reinstated from the DL on Saturday, Tim Britton of the Providence Journal reports.
Kelly wound up being sidelined for three weeks, and he hasn't pitched in a major-league game since July 9. Throughout the course of the 2017 season, the right-hander has posted a sparkling 1.49 ERA and 1.10 WHIP over 36.1 innings. Kelly figures to reside in high-leverage situations upon his return, although Addison Reed may be in line to work the eighth-inning setup role for Craig Kimbrel.
