In 20 appearances and 20 1⁄3 innings pitched in 2020’s 60-game COVID campaign, hard-throwing, recently-turned 28-year-old reliever Tanner Rainey put up a 2.66 ERA, 3.80 FIP, seven walks (3.10 BB/9), 32 Ks (14.16 K/9), and a .119/.213/.328 line against.
Opposing hitters who faced the Washington Nationals’ two-pitch pitcher combined for just a .149 batting average on his fastball (which averaged 96.6 MPH; down a bit from 97.7 MPH in 2019), and a .050 AVG on his slider (which averaged 87.1 MPH).
Rainey was shut down with forearm tightness late in the schedule, so his 2020 season ended on September 10th.
