In 20 appearances and 20 1⁄3 innings pitched overall this season, hard-throwing 27-year-old right-hander Tanner Rainey has a 2.66 ERA, a 3.80 FIP, seven walks (3.10 BB/9), 32 Ks (14.16 K/9), and a .119/.213/.328 line against. Opposing hitters facing the Nationals’ two-pitch pitcher have put up a .149 AVG on his fastball (which has averaged 96.6 MPH this season, down a bit from an average of 97.7 in 2019), and a .050 AVG on his slider (87.1 MPH).
Unfortunately, Rainey hasn’t been available over the last few days, and his manager, Davey Martinez, said he is experiencing tightness in his forearm.
