With consecutive 0 for 4 games, Salvador Perez is now hitting below .200 on the season. It has been a span of twelve games since Perez last had an extra base hit, which is his longest stretch on the season without doing so. In a hitter friendly National’s Park, take Perez to end a prolonged slump at the plate. He clears his combination line, and would not be surprised if it happens on a home run.

Washington has won three in a row by multiple runs and starts the third-most profitable pitcher in the majors tonight in southpaw Foster Griffin (7-2, 3.46 ERA). This most likely is not sustainable for the 30-year-old journeyman but you would be up $860 if you bet $100 on the Nats to each of his outings so far. No Royals have seen him career, and Kansas City fell to a truly hysterical 3-16 against lefty starters with Monday's four-run loss in D.C. (we cashed).

DraftKings. Foster Griffin has stayed under this hits allowed line in eight of his 12 starts this season, including four of five home outings. After a three-year stint in Japan, Griffin returned to the US this season armed with a seven-pitch mix, with all but one holding opponents to under a .240 batting average. Overall, Grffin has held opposing hitters to a .212 average - and even if he does regress towards his expected .242 xBA, this is still a high line. The Royals are only hitting .239 as a team against lefties this season. And albeit a small sample, Griffin has been much stingier on five days rest (.196 OBA), which could be a product of how starters were deployed in Japan.

We've reached the time of the season when it's time to fade Michael Wacha of the Royals. And if you've beaten me to it, you would've won your last six picks. Meanwhile, Foster Griffin has been on a roll for Washington, having allowed three or less runs in four straight starts. Also, Washington is 4-1 in his last five outings, with the one loss being an unimaginable 9-1 blown lead in San Francisco last Wednesday. Nonetheless, Kansas City's recent misery continues on Tuesday night with another road loss.
