After a brutal weekend in Oakland, the Nationals limp into Phoenix to face a Diamondbacks club that surprisingly has been among the majors’ worst so far this season (though Arizona has won seven of its last 10 to right the ship somewhat). Matt Williams, who played and coached for the D’backs and who lives in the area, returns home for the first time as a big-league manager, hoping to get his team back on track.
Jordan Zimmermann is on the mound for the Nationals, carrying a 10 1/3-inning scoreless streak with him into this start. He sports a 2.70 ERA in four career starts against the Diamondbacks, all four of them quality starts.
Right-hander Josh Collmenter gets the ball for Arizona, having given up nine runs (five earned) on 15 hits over his last 12 2/3 innings.
