Mariners vs. Nationals Pick
Moneyline Pick for Mariners vs. Nationals
- Mariners -140 (4 units)
Washington struck back with a win in Saturday’s contest but the fact remains that the pitching matchup favors Seattle in a big way here. Mikolas has bounced in and out of the rotation this season and has been roughed up by the long ball. Hancock has had some struggles of late but the fact remains that he still has solid metrics to fall back on, not to mention good strikeout numbers. Seattle is bound to improve offensively and roughing up Mikolas seems like a good place to start. Take the Mariners in the rubber game of this set.
Over/Under Pick for Mariners vs. Nationals
- Over 9.5 (4 units)
Seattle has seen the under post a 35-34-3 mark in their opening 72 games. The Mariners are 17th in the majors with 4.31 runs per contest though that number climbs to 4.53 runs per game on the road. Seattle has an average total of 8.21 runs per contest and that number climbs to 8.45 runs per game at T-Mobile Park. Washington entered Saturday having gone over the total in 43 of their 71 games, with three pushes, on the season. The Nationals are tied for 2nd in the majors with 5.38 runs per game, a number that falls to 5.18 runs per game at home. Washington has an average total of 10.70 runs per game and that number climbs to 11.42 runs per game at home this season. Both games in this series went over the number and this one likely follows suit. Take the over as a result.
