Game 26 lineups: Nats vs. Diamondbacks

After the most impressive offensive week and month in their history, the Nationals start anew tonight when they host the Diamondbacks in the opener of a three-game series. This is a good Arizona club that comes to town with the National League's second-ranked offense and second-ranked pitching staff.

One of those pitchers is Taijuan Walker, who takes the mound tonight. The young right-hander and former top Mariners prospect has opened the season 3-1 with a 3.94 ERA, having struck out 33 batters in 29 2/3 innings, but he has not faced a lineup like the one he'll face tonight.

Tanner Roark starts for the Nationals, looking to contain Paul Goldschmidt, Jake Lamb, Yasmany Tomás and the rest of the Diamondbacks' potent lineup. Keep in mind the Nats technically will only have 24 available players tonight, with the newly recalled A.J. Cole forced to serve the final three games of his suspension from the end of last season.
