News: Davis was recalled from Triple-A Syracuse on Sunday.
Impact: Davis has toiled in the minors since returning from the DL due to Tommy John surgery, but Drew Storen's ill-advised run-in with a locker forced the Nationals to need some bullpen help. In 48.2 innings across three levels in 2015, the 28-year-old has a mediocre 3.94 ERA and 1.646 WHIP. Control has also been an issue with a 5.06 BB/9.
