Sparkman allowed four runs on nine hits with two walks and three strikeouts across six innings to take the loss to the Nationals on Saturday.
The 27-year-old pitched better than he did in his last outing, but that's not saying much, as he yielded eight runs in three frames and is 0-2 with a 10.43 ERA during his last three starts. Sparkman is 2-5 with a 5.18 ERA, 1.43 WHIP and 34 strikeouts in 64.1 innings this year.
