He's been serviceable in that role, and while he is not a world beater, he's accomplishing what the Nationals need at this point in the season.Snell has been unhittable of late. Snell has allowed one run or less in seven of his last eight starts. He is precisely the starter San Diego wants on the mound as they try to hold on to the final Wild Card slot in the National League.Washington Nationals vs San Diego Padres Match DetailsFixture: Washington Nationals @ San Diego PadresTime & Date: Saturday, August 19, 9:40 p.m. EDTVenue: Petco Park, San Diego, CA View this post on Instagram Instagram Post"Petco Park" - sandiegotimesWashington Nationals vs San Diego Padres Betting Odds SpreadRun in the 1st?Team TotalsNationals+1.5 (+132)Yes (+105)Over 2.5 Runs (-106)Padres-1.5 (-160)No (-135)Over 5 Runs (-102)Washington Nationals vs San Diego Padres Best PicksSnell has been mowing over batters in his last four starts, averaging 8.5 Ks, making his prop today appropriately placed at 7.5.
