In back-to-back wins after a rough-ish MLB debut, Jackson Tetreault, 26, had given up four runs, one earned, in 13 innings pitched (0.69 ERA, 3.13 FIP), with opposing hitters in those outings putting up a .204/.264/.245 line against the right-hander, who put up solid if not spectacular numbers in five season in the Nationals’ system after Washington drafted him in the 7th Round in 2017.
“This kid comes up here and he’s very much under control,” Davey Martinez said after start No. 3 for Tetreault, a six-inning outing in Texas in which he gave up four hits and one run.
