There has been only one 10-game losing streak in Nationals history. It came all the way back in August 2008, the first year of operation at Nationals Park, when a team that went into the season believing it was good enough to win proceeded to lose 102 games. The streak would reach 12 games, but loss No. 10 came at home against the Rockies.

Tonight, the Nats will attempt to avoid reaching that ignominious 10-game mark again, and to do that they’ll have to beat the Rockies. This should be a favorable matchup for the home team, but as we saw Monday night and over the weekend when the Marlins were in town, there’s no such thing as a favorable matchup right now.

Colorado’s starting pitcher tonight is Antonio Senzatela. He is 1-10 with a 7.23 ERA this season. His lone victory came against the Nationals, who managed just one run in six innings against him on April 20 in the nightcap of a doubleheader at Coors Field. They scored that run in the top of the first, with James Wood drawing a leadoff walk, moving to second on Keibert Ruiz’s grounder and scoring on Nathaniel Lowe’s RBI single.

Michael Soroka did not pitch in that series, because he was on the injured list at the time. The right-hander is fully healthy now, but still seeking some consistency on the mound. Soroka sports a very solid 1.119 WHIP, with a strong 4-to-1 strikeout-to-walk ratio. So why does he also have a 5.14 ERA? Because he’s been prone to one or two critical mistakes per outing, which is most notably in the eight home runs he’s allowed over only 42 innings. He’s got to avoid those killer mistakes tonight if he wants to help pitch the Nationals to a desperately needed win.
