Mariners Nationals odds picks prediction spread over/under betting line

The Seattle Mariners (45-42) and Washington Nationals (30-58) play the second game of an interleague doubleheader Wednesday at Nationals Park. First pitch is scheduled for 6:05 p.m. ET. Let’s analyze Tipico Sportsbook‘s lines around the Mariners vs. Nationals Game 2 odds with MLB picks and predictions.

This analysis posted prior to Tuesday’s first game between Seattle and Washington.

This double-header will mark the first time the clubs have met this season.

The Mariners and Nationals were washed out in Tuesday’s interleague series opener, so now they’ll play two Wednesday. The M’s have played just one doubleheader this season, losing both games in a matchup at home against the Los Angeles Angels June 18.

The Nationals swept their first double dip April 19 against the Arizona Diamondbacks, but have lost in the second game of their 2 other doubleheaders this season.

Mariners at Nationals picks and predictions

Prediction

Nationals 4, Mariners 2

Money line

The NATIONALS (-103) are a strong play in the back end of the doubleheader behind Fedde. Yes, Fedde was turned up for 8 runs last time out in Atlanta, serving up 3 homers in the process, but he had allowed 3 or fewer runs in each of his prior 4 outings and won 2 of them.

Milone isn’t stretched out and this will be a bullpen game for the Mariners. That’s not a good thing in the second end of a double dip.

Run line/Against the spread

The ALTERNATE RUN LINE NATIONALS -1.5 (+185) is worth a small-unit play as a bet against the team’s former southpaw Milone. Washington hasn’t won a ton of games this season, but it will get the best of the left-hander.

Over/Under

The UNDER 9.5 (-115) is the lean in Game 2.

Entering Wednesday, the Under is 5-2 in the last 7 starts for the M’s against a right-handed starting pitcher.

For the Nats, the Under is 5-2 in the last 7 home games, while going 5-1 in the past 6 interleague games — not counting Game 1 of this doubleheader.

Over/Under (O/U): 9.5 (O: -110 | U: -110)

Mariners vs. Nationals picks and predictions

Prediction

Mariners 6, Nationals 5

Money line

The MARINERS (-108) are red-hot right now with 16 wins in their last 19 games and while cashing in 8 of their last 9 road outings. Seattle has also picked up a victory in 14 of its last 17 outings against a right-handed starting pitcher.

Gray has also struggled at home and it is hard to envision him cooling off the M’s right now.

Run line/Against the spread

The Nationals +1.5 (-180) are a little on the expensive side if you’d like a little insurance. Washington wouldn’t be a terrible play if the price was right, as Seattle has won 4 of its 8 games during the win streak by 1 run.

PASS.
