Maples (finger) was reinstated from the 10-day injured list Wednesday, Russell Dorsey of the Chicago Sun-Times reports.
Maples landed on the injured list due to a right middle finger blister in late July, but he joined Triple-A Iowa for a rehab assignment Aug. 11. Across nine rehab appearances, the right-hander posted an 8.64 ERA and 1.92 WHIP in 8.1 innings. He has a 2.28 ERA in 27.2 innings across 24 innings with the major-league club this year, but he hasn't been used in many high-leverage situations.
