Smith-Shawver will start Tuesday in Game 1 of the National League Wild Card Series against the Padres, David O'Brien of The Athletic reports.
With a doubleheader Monday and Chris Sale (back) unavailable, Atlanta's options for Game 1 were limited. Smith-Shawver made just one regular-season start with the big club, tossing 4.2 frames back in May versus the Cubs. Atlanta no doubt will have Smith-Shawver on a very short leash Tuesday.
