Washington Nationals at Seattle Mariners odds, picks and predictions

Analyzing Wednesday’s Washington Nationals at Seattle Mariners odds and lines, with MLB expert picks and predictions.

The Washington Nationals (41-83) take on the Seattle Mariners (67-56) Wednesday in the finale of a 2-game set at T-Mobile Park. First pitch is set for 4:10 p.m. ET. Let’s analyze Tipico Sportsbook‘s lines around the Nationals vs. Mariners odds with MLB picks and predictions.

Season series: Mariners lead 3-0

The Nationals couldn’t muster enough offense to slow down the hot Seattle club as they fell 4-2 Tuesday. The Nats are now 4-6 in their last 10 and 10-20 in their last 30 games. This is their final game of a 6-game road trip before flying home to face the Cincinnati Reds Friday.

The Mariners got it done Tuesday with 2-run homers by OF Mitch Haniger and 3B Eugenio Suarez. Seattle is 6-4 in its last 10 and 32-26 at home on the season. They welcome the Cleveland Guardians to town after this series so it’ll be important not to let it become a trap game.

Nationals at Mariners picks and predictions

Prediction

Mariners 6, Nationals 2

Money line

The Mariners were held in check to a degree Tuesday. They’ve scored 5.8 runs per game in the last 10 games, but have just plated 10 in the last 3. They’re due for an outburst. Let’s go with MARINERS OVER 2.5 TOTAL RUNS FIRST 5 INNINGS (-116) at a solid price. Sanchez has allowed 3 ER in 6 of his 7 starts.

Run line/Against the spread

The M’s are 2-1 on the RL against the Nats thus far. Washington just can’t keep pace offensively as they’ve scored 2.9 runs per game over the last 10. The MARINERS -1.5 (-135) is expensive so only put down a HALF-UNIT.

Over/Under

We’re projecting 8 runs here, but the Over 7.5 (-112) is heavily dependent on Washington scoring 3 runs, which they didn’t do Tuesday. There’s just too much risk for too little reward. PASS.
