Kieboom went 2-for-3 with two home runs and three RBI in Tuesday's spring game against the Astros.
Kieboom has put on a show in spring training, producing a 8-for-22 mark at the plate while drawing five walks in 14 games. Both of his home runs Tuesday notably came off Astros ace Justin Verlander, so the 21-year-old isn't merely feasting on overmatched pitching. Kieboom could return to Double-A Harrisburg after slashing .262/.326/.395 in 62 games last season, but is making the case for an early promotion. The Nationals have been giving him time at second base this spring with his big-league future in mind, as Trea Turner is entrenched as the team's franchise shortstop.
