A.J. Reed's two-out grand slam off Jacob Turner in the seventh erased a three-run deficit for the Astros.
Astros ace Dallas Keuchel, who had a disappointing 2016 after winning the AL Cy Young Award in '15, pitched three shutout innings in his first Grapefruit League start. Keuchel missed last September with shoulder inflammation, but he looked strong against a stacked Nationals lineup, allowing only one hit -- a third-inning leadoff double by Stephen Drew -- before inducing three consecutive groundouts to end his day.
Nationals starter Joe Ross also put together a stout outing, permitting two hits and one walk with four strikeouts over four scoreless innings.
